为了更加有效地满足 IEC60700-1标准规定的特高压晶闸管阀的试验要求，保证晶闸管阀运行试验回路的可靠、稳定运行，设计了一套控制保护系统。该系统由控制/保护主机、人机接口、触发脉冲控制装置、模拟量测量等功能模块组成，系统内的PCI总线、CAN总线和TDM总线用于各功能部分之间的数据传输。系统对试验回路的电流源/电压源和辅助设备独立控制、触发脉冲参数灵活配置、试验项目自动切换，整个试验过程灵活、稳定；保护系统实时监视系统运行状态，对一次回路提供全面、有效的保护，保证一次设备的安全。运行试验系统的试验结果满足各项试验要求，证明了控制保护系统的可靠性和有效性，为我国特高压晶闸管阀以及相关领域的研究和开发提供了坚实的基础和平台。%This paper presents a control and protection system for operational test of ultra high voltage thyristor valves to fully meet the requirement of IEC60700-1 specifications. The system is composed of control and protection hosts, HMI system, control device of converter pulse, analog measurement unit, etc. In this system, there are PCI bus, CAN bus, and TDM bus, which transmit data among functional units. By means of controlling circuit source, voltage source and auxiliary equipments, configuring parameters of converter pulse, switching test items automatically, the system makes the whole test process flexible and stable. The protection system provides comprehensive, effective protection for primary equipments by monitoring the status of the operational test system. The operational test results show that this C&P system is reliable and effective and provide a substantial base and platform for research and development of high voltage thyristor valves and related fields.
