Coordinated control ULTC power transformer with STATCOM for Voltage Control and Reactive Power Compensation
نویسنده
چکیده
The static synchronous compensator (STATCOM) is one type of FACTS devices which resembles in many respects a rotating synchronous condenser used for voltage control and reactive power compensation. The STATCOM can increase transmission capacity, damping low frequency oscillation, and improving voltage stability. This paper presents a control block diagram of STATCOM for the voltage stability improvement. The SIMULINK / MATLAB software „package‟ is used for simulation of test system. In this paper the STATCOM is connected with ULTC transformer to the 25KV line for a typical single machine infinite bus transmission system. The study demonstrates that STATCOM not only considerably improves voltage stability but also compensates the reactive power in steady state.
