Abstract

The invention provides a large power static var compensator based on SOPC and IGCT. The static var compensator includes a controller module and a power module. A system control panel employs a FPGA processor of a SOPC system which configures systems on a programmable slice. The controller module includes the system control panel and a driving conditioning plate. The system control panel and the driving conditioning plate conduct bilateral communications, wherein the driving conditioning plate includes an IO interface circuit, a signal conditioning sampling circuit, a driving circuit and a protection circuit. The power module and the driving circuit are connected for receiving driving of a PWM driving signal. The power module includes an integrated gate commutated thyristor (IGCT) module and a filtering circuit. An input end of the filtering circuit and an output end of the IGCT module are connected so as to conduct filtering treatment on an output signal of the IGCT module. According to the invention, the static var compensator can increase power density of system modules, increase operation efficiency and fault reaction speed of the system, and reduce link interference among chips.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a high-power static var compensation device based on SOPC and IGCT. Background technique [0002] Static var compensator STATCOM is a new type of reactive power compensation device, which can greatly improve the voltage stability in the power system, thereby improving the transmission capacity, and is widely used in load compensation and transmission line compensation of modern power systems. The controller module of the prior art static var compensator STATCOM cannot realize algorithmic control and efficient centralized processing of detection parameters, and has disadvantages such as low response speed, serious signal interference and low power density. [0003] Patent CN 103036241A discloses a reactive power compensation controller and its control method, which can improve the working efficiency of the compensation system and reduce losses. However, this patent uses a D...
