采用频率相关网络等值的 RTDS-TSA 异构混合仿真平台开发

摘要

大规模交直流混联电网的仿真，既需要考虑直流部分仿真的精细性，也要兼顾整体的仿真效率。因此文中将实时数字仿真器(RTDS)和机电暂态稳定分析(TSA)程序结合在一起提出一种异构的 RTDS-TSA 实时混合仿真平台。该平台采用 GTFPGA 板卡作为两者间高速数字化通信接口，同时实现了频率相关网络等值(FDNE)以提高仿真精度。通过一个由新英格兰39节点系统更改而来的含直流线路的测试系统，验证了所开发平台的正确性。%For the simulation of large-scale AC/DC hybrid systems,both the precision of the DC parts and the efficiency of the whole system should be considered.Thus a real-time hybrid transient simulation platform is proposed by combining the real-time digital simulator(RTDS) and a transient stability analysis(TSA) program.A latest GTFPGA card is used to realize the high speed digital communication between RTDS and the computer deploying TSA program. Moreover, the frequency dependent network equivalent (FDNE) is implemented in this simulation platform to improve the accuracy of simulation results.By simulating a modified New England 39-bus test system incorporating high-voltage direct current (HVDC) components,the validity of the proposed simulation platform is verified.
