The Effect of the Synchronizing Signal and the Circuit Data on the Dynamic Characteristics of TCSC

This paper points out that the different synchronizing signal and the circuit parameter arise themain effect on the dynamic characteristics and the control accuracy of the thyristor controlled series compensator(TCSC) with the numerical emulation and the dynamic simulation. It analyses the TCSC dynamic dampingcharecteristics from equivalent concept, and obtains the conclusion that can cut down the response time of theimpedance adjustment in close-loop control. Research shows that rational selection of the synchronizing signaland adoption of the special hardware Block and Bypass control mode can decrease effectively variousintederence, realize the fast interehange between the working regions in the three-phase operation on the TCSCapparatus, realize the fast steady operation, cut down the response time of dynamic adjustment, eliminateeffectively the DC component, and improve the dynamic control charateristics.
