Title: Modeling and Simulation of UPFC for Power Quality Improvement   

Author Name: S. Muthukrishnan, A. Nirmal Kumar   

Synopsis:   

This paper deals with digital simulation of power system using UPFC to improve the power quality. The UPFC is also capable of improving transient stability in a power system. It is the most complex power electronic system for controlling the power flow in an electrical power system. The real and reactive powers can be easily controlled in a power system with a UPFC. The circuit model is developed for UPFC using rectifier and inverter models. The control angle is varied to vary the real and reactive powers at the receiving end. The Matlab simulation results are presented to validate the model.
