柔性直流输电阀基控制设备硬件在环测试方法

Hardware-in-the-Loop Test Method for Valve Base Controller of VSC-HVDC

张北柔性直流电网工程是世界首个柔性直流电网工程,对阀基控制设备的可靠性提出了更高的要求。为了更全面测试柔性直流输电阀基控制设备,提出了高压大容量柔性直流输电阀基控制设备全规模接入实时仿真系统实现硬件在环测试的方法。通过研制接口机箱,搭建了基于RT-LAB的北京站阀基控制设备全规模接入测试平台,提出了全面的阀基控制设备测试项目及测试方法。对该平台的几个典型工况试验波形的研究表明,所搭建测试平台在阀基控制设备测试方面的全面性和准确性;该测试平台已在张北柔性直流电网工程阀基控制设备的出厂测试中得到应用,可为其他柔性直流输电工程阀基控制设备的测试提供借鉴。

The Zhangbei flexible DC power grid project is the world's first voltage source converter based high voltage direct current(VSC-HVDC)project,which brings higher requirements for the reliability of valve base controller(VBC).In order to comprehensively test the VSC-HVDC valve control equipment,a hardware-in-loop test method is proposed in this paper for the fullscale accessing of high voltage and large capacity VSC-HVDC VBC to the real-time simulation system.Through developing an I/O interface chassis,a full-scale access testing platform for VBC in Beijing Station was built based on RT-LAB,and the comprehensive test items and test methods for VBC were proposed.By studying the testing waveforms of several typical working conditions of the platform,the built platform is proved effective and accurate for VBC testing.This test platform has been applied in the certificate of analysis(COA)of VBC in Zhangbei VSC-HVDC Project,and it can also provide reference for the VBC testing in other VSC-HVDC projects.
