摘要
通过对国外换流阀生产厂家ABB、Siemens、ALSTOM三家公司换流阀及其阀控系统的硬件结构、软件功能以及阀控与直流控制保护系统的接口进行了阐述,对直流输电设备国产化后不同技术路线的直流控制保护系统与阀控系统的接口进行了说明,结合换流站运行经验和目前阀控系统存在的缺陷与隐患以及直流设备运行过程中的几次重大事件,提出改进建议,为规范国内直流控保与阀控系统通讯接口提供参考依据。
In this paper, hardware structure, software functions and interface between valve con？trol system and DC control protection system of converter valve and valve control system from threeforeign manufacturers are expatiated including ABB, Siemens and ALSTOM. The interfaces betweenthe DC control protection system and the valve control system of the different technical routes afterthe homemade of the DC transmission equipment are explained. Combined with the operation experi？ence of the converter station and the defects and hidden dangers existing in the current valve con？trol system, and several important events in the process of the DC equipment operation, the im？provement suggestions are put forward, which provides reference for regulating the communicationinterface between DC control protection and valve control system in China.
