FIRING ANGLE SVC MODEL FOR ANALYZING THE PERFORMANCE OF TRANSMISSION NETWORK USING NEWTON RAPHSON LOAD FLOW

This paper deals with Power flow, which is necessary for any power system solution and carry out a comprehensive study of the Newton- Raphson method of power flow analysis with and without SVC. Voltage stability analysis is the major concern in order to operate any power system as secured. This paper presents the investigation on N-R power flow enhancement of voltage stability and power loss minimization with & without FACTS controllers such as Static Var Compensator (SVC) device. The Static Var Compensator (SVC) provides a promising means to control power flow in modern power systems. In this paper the Newton-Raphson is used to investigate its effect on voltage profile and power system lossess with and without SVC in power system.. Simulations investigate the effect of voltage magnitude and angle with and without SVC on the power flow of the system. This survey article will be very much useful to the researchers for finding out the relevant references in the field of Newton-Raphson power flow control with SVC in power systems. In order to reach the above goals, these devices must be located optimally. In this paper the Optimal placement of SVC is carried out by Voltage collapse Prediction Index (VCPI).The size of the SVC is determined by suitable firing angle which reduces the losses in the system. Simulations have been implemented in MATLAB Software and the IEEE 14 and IEEE 57-bus systems have been used as case studies.
