摘要
针对上海西郊变电站±50 Mvar静止无功发生器(STATCOM)示范工程,提出了面向大功率电力电子装置的实时数字模型建立方法和数值计算方法,并基于数字信号处理器(DSP)和现场可编程门阵列(FPGA),设计和实现了±50 Mvar STATCOM实时数字仿真平台,通过与离线电磁暂态仿真工具PSCAD/EMTDC的仿真结果的对比研究,验证了其有效性和正确性。所设计的实时数字仿真平台在±50 Mvar STATCOM现场调试和投运过程中得到了成功应用,大大缩短了现场调试周期。
This paper describes a method for time domain electromagnetic modeling for a ± 50 Mvar static compensator （STATCOM） using a 21-level cascaded converter. The real-time digital simulation algorithm based on the time average method is also presented. Based on digital signal processors （DSPs） and field programmable logic gates （FPGAs）, a real-time digital simulator is designed and implemented for the ±50 Mvar STATCOM system. By comparing with the simulation results from PSCAD/EMTDC, the real time digital simulation results are verified. The designed real time digital simulator has been used to test the actual controller when commissioning the ±50 Mvar STATCOM in Shanghai Xijiao Substation.
