“MULTICONTROL FUNCTIONAL STATIC SYNCHRONOUS COMPENSATOR (STATCOM) IN POWER SYSTEM STEADY STATE OPERATION”

Electrical Engineering

The development of the modern power system has led to an increasing complexity in the study of power flow operation and also presents new challenges to system stability. Stability plays a significant role in ensuring the stable operation of power system with continuous power flow operation without any limitations. Flexible alternating current transmission system (FACTS) is an application of a power electronics devices which is used to control the power flow and to improve the power system stability. From family of FACTs devices, STATCOM is one of the recently developed converter based Flexible Alternating Current Transmission System controller which has the ability to control all parameters of power system such as voltage, impedance and phase angle. The study of steady state model of STATCOM is carried out here by the use of Newton-Raphson power flow. Multi-control functional model of a STATCOM for power system steady state operation is studied and discussed and standard IEEE bus test systems are used to illustrate the multi-control functional model of a STATCOM, voltage control specifically. The model is simulated by using MATLAB software.
