A novel HIL bench with a cost-effective input and output interface between the control system under test and the real-time simulator is introduced. Two critical test cases, namely the start-up of the MMC connected to islanded networks and the AC fault in the bus close to the MMC substation are studied. The validity of the proposed methodology for the dynamic performance test is confirmed by comparing the results from the HIL test and the actual waveform recorded from the field, after the MMC is commissioned.
这篇文章介绍了利用硬件在环（HIL）仿真对多终端MMC HVDC系统的控制保护系统进行动态性能仿真。文中介绍了一套在被测试控制系统中且具备高性价比的输入输出接口HIL平台和涉及到的实时仿真器。两项关键测试案例--与独立网络连接的MMC启动和靠近MMC变电站的总线中的交流故障—在文中得到研究。MMC开始使用后，通过HIL测试和现场真实录波的对比，针对动态性能测试所提出的方法的有效性得到了证实。
