摘要：ABSTRACT: This paper presents for discuses how Static Var Compensator (SVC) has successfully been applied to control transmission systems dynamic performance for system disturbance and regulate system voltage and power flow models of static Var compensator (SVC) and current Sourced Inverter (CSI) based Flexible AC Transmission System (FACTS) Controllers. SVC is basically a shunt compensative device. The static Var generator whose output is adjustable limits to exchange capacitive or inductive current so as to maintain or control specific power variable; typically, the control variable is the SVC bus voltage. One of the major reasons for installing a SVC is to improve dynamic performance control and thus increase system reliability. 'This paper presents a control block diagram of SVC for the dynamics performance improvement. The MATLAB/SIMULINK model is used for simulation of test system. In this paper the SVC is connected to shunt with the 220KV line for a typical two machine transmission system. Due to its simplicity, robustness and easy implementation, proportional integral derivative (PID) controller along with feedback signals are used to control the inverter firing angle and hence control the reactive power exchange between the AC system and the SVC.
