Variable VAR compensator circuits
A family of two reactive-power compensator circuit is presented. A general model of some basic linear elements and switching function blocks is developed first. Then the two proposed compensator circuits are derived from the generalised model. The proposed circuits are capable of supplying leading as well as lagging reactive currents in stepless variation without using an inverter configuration...
متن کاملDesign, Fabrication and Implementation of Microcontroller Controlled Static Var Compensator
Power factor correction is vital in present society. The two key benefits of power factor correction, which includes reduced power costs and higher system capacity. Implementation of Flexible AC Transmission Systems (FACTS) improves the power factor, power transfer capability and voltage stability. The shunt type of FACTS controller is used to either absorb or inject VARs into the system, there...
متن کاملThyristor Controlled Series Compensator - based Controller Design Employing Genetic Algorithm : A Comparative Study
technique is applied to design a Thyristor Controlled Series Compensator (TCSC)-based controller to enhance the power system stability. Two types of controller structures, namely a lead-lag (LL) and a proportional-integral-derivative (PID) are considered. Further, for the optimization of proposed controller parameters, two objective functions namely Integral Square Error (ISE) and Integral of T...
متن کاملFuzzy control of thyristor-controlled series compensator in power system transients
Power system transient stability is one of the most challenging technical areas in electric power industry. Thyristorcontrolled series compensation (TCSC) is expected to improve transient stability and damp power oscillations. TCSC control in power system transients is a nonlinear control problem. This paper presents a T–S-model-based fuzzy control scheme and a systematic design method for the ...
متن کاملImproving Pacific Inter-tie Stability Using Existing Static VAR Compensators and Thyristor Controlled Series Compensation
The paper summarizes new control designs developed at Washington State University for the control of existing SVC’s, and TCSC owned by Bonneville Power Administration. The new controls are primarily aimed at improving transient stability of the WSCC western electric power system. The proposed controls are heuristic and are nonlinear. They are shown to be very effective in increasing the operati...
