Enhancement Of Pq For Nonlinear Loads By Sapf And Facts...

Enhancement of PQ for nonlinear loads by SAPF and FACTS DEVICE Nomula Sai Narendra sathayanarayana.p SNIST, SNIST sainarendran@sreenidhi.edu.in,sathanarayanapolisetty@sreenidhi.edu.in Abstract: The power quality (P.Q) arise mainly due to the PE equipment’s. In this paper presents the difference of simulation study of PI controlled based STATCON (STATCOM also called be STATCON) and shunt active power filter (SAPF). So, in order to improve the P.Q by sending or receiving the reactive power relay upon the necessity for load. And migrates the harmonics by injecting current into the scheme. So, that total harmonic distortion value of source current is decreased. Key words: Power Quality, STATCON (static synchronous condenser), shunt active power filter,PI controller, hysteresis controller. I. INTRODUCTION At the beginning, the device was modeled to endure distortions suchas low resistive paths plus transient overloads without more amounts. The cost of present PE devices could be higher if the device was modeled with the same hardiness. Due to the introduction of nonlinear loads into the power systems pollution has obtained .Still;the present level distress ratio has not arrived. Here, due to nonlinear characteristics and speedy switching of PE the PQproblems are generated. An alternate choice over the Passive Filter is active power filter to compensate the current harmonics and requirement of reactive power for the nonlinearloads. So, long for SAPF
