摘　　要：纯数字仿真软件不能真实模拟柔性直流输电系统控保装置响应特性,用其检验控制保护装置的总体功能,优化、验证控制保护参数存在一定误差,因此本文建立了一个基于RT-LAB的模块化多电平换流器半实物仿真平台,采用高速协议转换控制机箱实现数据合并以满足通信接口高速率的要求。针对控制保护装置性能,设计了站控和阀控的测试方案,并利用所搭建平台完成了对实际控保装置的相关动态性能测试和功能测试,验证了MMC半实物仿真平台的有效性以及测试方案的合理性,能达到检验控保装置性能的要求。Since the pure digital simulation software cannot realistically simulate the response characteristics of the control and protection device of the flexible HVDC transmission system,there is some errors if it is used to check the overall function of the control and protection device,optimize and verify the control and protection parameters.A hardware in the loop(HIL)simulation platform based on RT-LAB is established in this paper.The data merge is realized by the high-speed protocol conversion control chassis to meet the high speed requirement of communication interface.In view of the performance of the control and protection device,a test scheme of converter station control and basic valve controller is designed,and the relevant tests are completed based on the built platform.The dynamic performance test and the function test verify the validity of the MMC hardware in the loop simulation platform and the rationality of the test scheme,which can meet requirements of the control and protection device performance testing.
