An efficiency hardware-in-the-loop(HIL)simulation method of cascaded static synchronous compensator(STATCOM)based on field programmable gate array(FPGA)is proposed,utilizing the parallel computing technology of real-time digital simulation system(RTDS)DSP and GTFPGA unit to implement real-time calculation of STATCOM main circuit model.STATCOM valve controller is connected to the RTDS system through high-speed optical fiber interface.The simulation system has the advantages of high efficiency and using less RTDS hardware resources,which make up for the shortcomings of the existing HIL real-time simulation scheme of cascaded STATCOM.The chain STATCOM system with the same number of sub-modules as the actual power valve set and HIL real-time simulation of several STATCOM regional power grid systems are realized.The validity and accuracy of the simulation system are verified by checking the characteristics of the dynamic simulation test with STATCOM actual samples.The simulation test system has been applied to the actual engineering design scheme check of STATCOM and the function test and performance verification of control system.
