Abstract

In the present time, the multi-phase motor especially five phase Permanent Magnet Synchronous Motor (PMSM) machines are being popular and used in many industrial applications with efficient performance. The main features of this machine are its reliability and excellent dynamic performance. Due to these features, this permanent magnet motor is widely being used in automotive or high power traction systems. However, the possibility of failures during motor operation cannot be denied and further it leads to large revenue losses for industries. In PMSM machines, diagnosis of magnetic demagnetization has been a challenging task for many researchers since last decade. Thus, condition monitoring of this motor for magnetic demagnetization is very essential. Therefore, in this research paper, the magnetic demagnetization of the motor has been diagnosed precisely in the early stages by the advanced Motor Current Signature Analysis (MCSA) technique.

Abstract

Solar energy will be changed by climatic conditions. Photovoltaic solar power generation is very sensitive to shading effect. Output of solar PV cell will be lessen, when a small part of a solar PV array is shaded. For solar photovoltaic systems, energy storage such as batteries and fuel cells has attracted considerably and demand for solar photovoltaic systems with energy storage devices has increased. If solar photovoltaic systems become a constant source of energy, resulting in improvement in solar photovoltaic values as well as performance. This article outlines a new converter called reconfigurable solar converter (RSC) for photovoltaic (PV) cells, especially for utility-scale PV applications. This document also includes MATLAB simulation and its results analysis. The main concept of the new converter is to use a single stage three-phase solar inverter for the DC / AC and DC / DC processes described in this document. This converter solution is attractive for photovoltaic systems with battery backup applications because it reduces the number of conversion stages, thereby increasing efficiency and reducing cost, weight and size. This document is very important for applications that are used to interpret the performance characteristics of the proposed RSC. This document proposes a new topology for the RSC that allows the use of a higher battery voltage than photoelectric voltage. The RSC concept is applied in local consumer optical battery applications. A range of RSC operating modes is suggested for optimal home use. Automatic change between these operating modes is another objective of this document.

Abstract

Weight is a critical factor in the design of deep space vehicles. Space bound electrical systems can be constructed to weigh less if designed as high voltage, high frequency AC power system. However, high voltage and high frequency power distribution systems have severe limitations in space exploration due to voltage breakdown and electrical discharge phenomena. Paschen law gives the breakdown voltage necessary to start a discharge between two electrodes in gas medium as a function of pressure and gap length. In the traditional experiment to verify Paschen law, pressure in a controlled vacuum chamber is set while a DC voltage across two electrodes is varied. This paper takes the reverse procedure, i.e., AC voltage across electrode gap is set and pressure in the vacuum chamber varied. The intention for this experimental approach is to allow for observation of changes in the voltage across the electrode gap before, during and after voltage breakdown. At Nyquist sampling rate, the result recorded in the experiments is a near continuous graphical chronology of changes and oscillations in voltage across the electrode gap due to electron collision activities between the electrodes.

Abstract

Lightning strikes have great importance in balancing electron distributions of our earth. In this study, it is aimed to model lightning strikes which occur in nature by using two-dimensional investigation. For this purpose, firstly, lightning is simulated in computer environment by using finite element method at different matrix sizes. In the next step a fractal analysis method is used to determine the similarity of the model to the actual lightning. In order to simulate and predict possible pattern of a real lightning the lightning paths investigated and nature of the strike is simulated. According to the simulation results, the fractal dimension averages of the shapes are obtained as 1.32 by using the MATLAB program. On the other hand, real lightning images are processed and average fractal dimension is calculated as 1.23. This results have verified that simulation results and real images results are very close in terms of fractal dimensions. Accordingly, the fractal irregularity of the simulated shapes is slightly more than the actual lightning.

Abstract

The photovoltaic technology is one of the base sources of distributed generations for future generation, but it lacks certainty in power production. Absence of transformer in DC/AC conversion will reduce the cost and volume of the PV inverter. The absence of transformer creates galvanic isolation problem that produces leakage currents between grid and PV panel. The grid connected PV inverters with bipolar SPWM is able to supply active and reactive power to grid. The bipolar SPWM has high switching losses and voltage stress across the filter inductor, which is double the supply voltage. The conventional unipolar SPWM mitigates voltage stress and switching losses, but it lacks reactive power capability. In this paper, a new topology is proposed to give solutions to the above mentioned problems associated with reliability, leakage currents, and reactive power capability in a single topology. A transformerless H6 inverter is used to reduce leakage currents. A modified unipolar SPWM technique is applied to H6 inverter to mitigate voltage stress and switching loss with reactive power capability. A battery storage system is also connected between PV panel and inverter to make PV system reliable at least in power supply.

Abstract

This paper deals with interaction of 10 kW Solar PV system with grid and study of real power flow from Solar PV to the load and to the grid. The proposed PV power plant system is modeled using MATLAB/Simulink software and its performance is studied. The whole system deals with simulation of a PV panel, MPPT controller, boost converter, and 3ɸ VSI and the control algorithms used in the system. The Solar Photovoltaic system has a MPPT tracking system with DC-DC boost converter to track the maximum power from the solar panels. The MPPT technique implemented in this system is the Modified Perturb and Observe method which is used to improve the efficiency of the system. The interface between grid and solar PV is carried out through a Voltage Source inverter and thus eliminating the current harmonics based on a control technique used in Voltage source inverters. The analysis and control design of grid connected PV inverter using PI control technique is performed in synchronous d-q rotating reference frame to achieve maximum output voltage response and active power. The SPWM (Sinusoidal Pulse Width Modulation), SRFT (Synchronous Reference Frame Theory) and IRPT (Instantaneous Reactance Power Theory) inverter techniques are implemented to control the proposed solar photovoltaic system. A current control strategy with PWM technique is proposed to provide pulse for VSI. This system demonstrates the elimination of harmonics and improves power factor.

Abstract

The cost of fuel is getting increased and the effect of gases being emitted from the burnt fuel is weakening the ozone layer. Carbon emission has also become a big challenge in today's world. Therefore, by using solar power, we can reduce carbon footprints. Lawn mowers are becoming popular now-a-days. Grass cutting being a tedious work for human beings, can be simplified by using an automatic grass cutter, which can be performed without a physical person being present. While cutting the grass, there are some obstacles, which obstruct the cutting of grass and sometimes the blades of the machine get damaged, so it is necessary to avoid obstacles. For that we have to identify the obstacles first and then we have to change the path of the lawn mower. Supplying power to the lawn mower is a big issue while designing the model. In this paper, the authors have used a solar panel to charge the battery and the power stored in the battery is utilized to power the electric motors, which will rotate the blades to cut the grass.

Abstract

The objective of ELD is to determine economic sharing of generating power from different generating stations to meet the demand while satisfying the constraints. Power scheduling is one of the most important problems in the optimization of operation price of the power system. In deregulated power system environment Economic load dispatch (ELD) has the objective of generation allocation to the power generators such that the total prices paid to Gencos is minimized and all operating constraints are satisfied. Various techniques are available to address ELD and other power system optimization problems. The soft computing techniques like particle swarm optimization (PSO), GA and lemda iteration are being used to improve the optimization results. This paper presents and compares the performance of the PSO, GA, and ABC with conventional ELD method for optimization of pool prices. A study on IEEE 26 Bus System has been made for calculating transmission Prices for Bilateral Contracts between GENCOs and DISCOs at different buses. Intelligent techniques have been applied to optimize pool prices and minimizing transmission losses. Transmission pricing are calculated using MWmile method. The results of these techniques are compared, which show better performance of ELD+PSO method over ELD+ABC and ELD+GA methods both.

Abstract

This study presents the theory and modelling of a novel controller based on PWM - based Series Vectorial Compensator (SVeC). This is a new series Flexible AC Transmission System (FACTS) controller for active power flow control in a transmission line and damping of low-frequency oscillations (LFO). This paper presents the basic module, steady- state operation, mathematical analysis, current injection model and dynamic model of SVeC. The main contribution of this work is that a current injection model of the SVeC for studying the effect of the SVeC on the LFO is proposed. A brief comparison of the Coordinated Control (COC) of SVeC and Power System Stabilizer (PSS) with without control is presented for dynamic series compensation of transmission lines. The multi machine network is used for comparison purpose. The performance of the proposed controller is checked through eigen-value analysis and non-linear time domain simulations under nominal load operation. The results obtained show that the proposed control is efficient for studying the effects of SVeC on the electro mechanical oscillations and it has better oscillation damping characteristics than without control.

In this paper a new Power factor correction bridgeless Single Ended primary Inductor Converter (SEPIC) is designed for universal input voltage applications is presented in this paper. Now a days entire our electrical grid connected with nonlinear loads, so there is a need to improve power factor implied on the grid as well as power quality. The main drawbacks of the conventional SEPIC PFC is lower efficiency due to the conduction losses of the diodes. To improve efficiency of the system, a modified bridgeless SEPIC converter is proposed in this paper. The proposed modified PFC coverter offer higher operating efficiency with high gain. The high gain is obtained by multiplier circuits. The main advantages of the proposed system is diode bridge circuits completely eliminated for conventional circuits and also control circuit is very simple. The proposed converter is analysed interms of THD and also analysed gain of the converter with respect to the different duty cycle varying from 10% to 90%. The proposed converter is analysed with mathematical expressions. The results of the modified PFC have been verified using MATLAB Simulink.

Abstract

In the present scenario, the renewable energy sources solar and wind are used locally by creating a Nano grid. In the integration of these sources to the Nano grid, hybrid converters play an important role to provide both AC and DC loads. Existing hybrid converters suffer with limitations such as no protection for shoot through condition and separate converters are used to supply AC & DC loads, which increases the size and cost of the system. A boost derived hybrid converter which provides both AC and DC output has overcome the above limitations. Further, this converter operation is unstable under unbalanced loading conditions and also its boost gain is low. To improve the performance of boost derived converter the proposed work presents a SPWM scheme based boost derived hybrid converter. The proposed hybrid converter is modeled in MATLAB/PLECS Simulink and its performance is verified under no load and different loading conditions. A laboratory hardware model is developed to validate the Simulink model results. It has been observed that both laboratory model results and Simulink model results are in good agreement with each other. It has been seen that boost derived converter with SPWM scheme has performed better than the PWM based converter.

Abstract

The aspect of lamp expectancy for compact fluorescent lamps (CFL) has already been explored by many lighting engineers. It is also well understood that there several parameters that are always influencing the life and performance of CFLs. The parameter such as lamp current crest factor happens to be a pivotal piece of information in connection with lamp life. It has been observed experimentally that the range of lamp current crest factor should be 1.9 to 2.1 for CFLs. Thus implying a reliable heating of the lamp electrodes without any damage. In most of the high power factor (HPF) lamps it has been observed that the lamp current crest factor is within the prescribed limit. But however if the electrode heating is not sufficient it will result in sputtering of the electrode coating and if it more than sufficient evaporation will occur. In both the cases the lamp electrodes are prone to damage. It has been observed that the lamp starting voltage is an important parameter that governs the necessary and sufficient heating of the lamp electrodes. In this paper explores the impact of high power factor (HPF) circuit on the life of self-ballasted lamps by analyzing the lamp voltage crest factor. The experiment carried out on different types of 18W lamps data for lamp voltage crest factor has been collected.  The research work done in this paper provides information about the lamp voltage crest factor with corresponding change in electrode temperature. The lamps used in this paper are put to accelerated test with 5 minutes on and 5 minutes off cycle. The lamps with improved circuit is compared with the other types. The lamp voltage responsible for preheating is finally considered while regulating voltage crest factor using IR215X IC for the lamp ballast. The degradation of lamp life is observed physically. The data is plotted in MATLAB and analyzed. An empirical relation has been derived from the curve fitting tool with the set of results obtained. This work serves an important aspect of HPF circuitry as it explores an ingenious parameter influencing the life of CFLs.

Abstract

In the paper, the slip frequency control of Induction Motor (IM) is analyzed and developed the control loop with the help of hybrid technique. The hybrid technique is the combination of Adaptive Neuro Fuzzy Inference System (ANFIS) and Firefly Algorithm (FA), which is works based on the Phase Locked Loop (PLL). Here, the FA is developed to train the ANFIS and established the rule based layer formation. The bio-inspired optimization technique of FA is applied to develop the performance of ANFIS by tuning the membership function and reduce the error value. After that, the ANFIS is designed and this is suggested for the enhancement of stability and controlling the speed, torque and slip frequency. In the controller part of analysis, the IM behaviors are determined normally. After that, the error speed signal is calculated, and established on the comparison of reference and motor speed. The resulted error and change in error speed signals are used to the input of the proposed hybrid controller loop. The speed characteristics of IM is analyzed with the help of proposed technique. The proposed method is implemented in MATLAB/Simulink platform and compared with the existing methods such as, ANFIS and Particle Swarm Optimization (PSO) algorithm. In order to prove the effectiveness of the proposed method, the characteristics of speed, torque, slip frequency and current are evaluated.

Abstract

Estimation of power system parameter plays an important role in the modern power system. In this paper estimation of harmonics components in a power system synthetic signal is done by an improved estimation techniques called as ADALINE. This neural estimator basically uses an adaptive interpreted linear neuron. Learning parameter is adjusted to keep the difference between the Real values and Expected values to satisfy the difference arises due to error equation. Tracking of the fourier co-efficent of the proposed signal, which is also constitutes a noise and DC decaying component can be done easily and accurately using the proposed algorithm. To verify the effectiveness of the proposed algorithm estimation of amplitude as well as Phase of fundamental and harmonics is carried out. The simulation results obtained are encouraging to work more on estimation of signal.
