Regulating device of static var compensator

Abstract

The invention discloses a regulating device of a static var compensator, which is characterized by comprising a control module, an auxiliary control module, a measuring module and an executing module, wherein the measuring module is used for collecting analog values to be processed and analyzed in a power system and simultaneously carrying out data processing and analysis so as to obtain various variables for a control algorithm, and the measuring module can also be used for realizing the functions of current collection and processing as well as voltage collection and processing; the control module is used for obtaining an offset value through the comparison between the measuring module and a control target, sending the offset value to a fuzzy self-adaptation PI (Proportion Integration) regulator, working out a control parameter to be sent to an executing structure and guiding the executing structure to complete the control; and the executing module is responsible for the specific physical realization of a controlled variable worked out with the control algorithm so as to complete the control of the power system. The regulating device provided by the invention has the advantages that an FPGA (Field Programmable Gate Array) is used for realizing pulse triggering to obtain higher triggering angle precision (within control precision) and guarantee the real-time property and the accuracy of the triggering of a thyristor; the fuzzy self-adaptation control accelerates the response speed and improves the system performance; and the regulating device can be connected outwards through optical fibers and has stronger insulation and anti-jamming capabilities.

Description

Technical field [0001] The invention involves a static non -merit compensator, especially a regulatory device for static non -merit compensators. Background technique [0002] Static non -merit compensator (SVC) is a powerless compensation device for controlling or switching devices for power -free devices (capacitors, electrical antibodies).The impact of powerless power on the power grid cannot be ignored. In order to improve the power supply quality of the power system, it is necessary to adjust the powerless power.The role of non -contribution compensation is mainly reflected in the following aspects: improving the power factor of the power supply system and load; stabilizing the electrical end and power grid voltage, and improving the quality of power supply.Setting a dynamic powerless power compensation device in long -distance transmission cables can also improve the stability of the transmission system, inhibit the power shock of the transmission system, and improve the po...
