Analysis of Thyristor Switched Three-Phase Capacitor

Abstract:

it can limit the reactive power transmission to improve the voltage quality of power grid by installing parallel capacitors for reactive power compensation. But due to presence of transient transition process during power capacitors switching, it will seriously affect the service life of power capacitors and the safe operation of power system if the switching process of capacitors is not properly controlled. Firstly, this article described the fundamental principle and switching conditions of Thyristor Switched Capacitor (TSC). Secondly, the selection of switching time was analyzed for Thyristor Switched Three-phase Capacitor (TSTC). Finally, the simulation for TSTC was carried out by using MATLAB to verify the feasibility of analysis.
