Abstract

The invention discloses a TCSC (thyristor controlled series compensator) and SVC (static var compensator) joint debugging control system based on a saddle node bifurcation theory. The system is characterized by comprising a saddle node bifurcation self-adaptive controller, a communication channel, a TCSC control unit, an SVC control unit, a phase-control reactor loop TCR (temperature coefficient of resistance) branch, a first joint debugging control system and a second joint debugging control system; and a working method of the system comprises the steps of state judgment, data processing and analysis, instruction transmission, judgment stabilization and action in accordance with instructions. The system has the advantages that firstly, a voltage is debugged smoothly, and the voltage has small fluctuation; secondly, the network loss is reduced and balanced inactively at the scene; thirdly, the interinfluence between FACTS (facilities administration control and time schedule) devices is reduced; fourthly, the operability is high, the cost is low, and the operation is simple; and fifthly, an adjustable space is provided for the inactive voltage optimization while a system enters a small amplitude change period in an inactive load way.

Description

(1) Technical field: [0001] The present invention belongs to the application field of power electronic technology in power system, especially a kind of TCSC (Thyristor Controlled Series Compensator—controllable series compensation device based on thyristor) and SVC (Staic Var Compensator—— static var compensation device) joint debugging control system and its working method. (2) Background technology: [0002] SVC is composed of phase control reactor (ie TCR), harmonic filter, shunt capacitor and control system, which can realize reactive power smooth compensation. The SVC mainly solves the problem of reactive power compensation of the power grid under transient conditions. It can ensure the stability of the grid voltage and the adjustment process is smooth. Especially in severe weather conditions, the SVC device can also realize the rapid melting of ice on the transmission line, which is irreplaceable. status. However, with the improvement of power grid safety management ...
