摘　　要：在高压直流输电的控制系统中,换流器控制级用于控制换流器的触发相位,并实现直流侧的定电流、定电压和定关断角控制。在直流输电工程中,控制系统多以SIEMENS或ABB公司的控制策略为基础,而CIGRE HVDC标准测试模型因结构简单、具有借鉴性而被广泛用于直流输电的研究。因此,对CIGRE HVDC标准测试模型、SIEMENS和ABB的基本控制策略进行比较,并分析不同控制配合方式下系统暂态性能和换相失败免疫性能,对直流输电测试模型的改进和完善具有重要作用。首先对CIGRE、SIEMENS和ABB 3种基本控制策略进行介绍,基于CIGRE HVDC标准测试模型分别搭建了以SIEMENS、ABB基本控制策略为基础的控制系统,仿真分析了3种控制策略下系统的稳态和暂态响应,并对比了3种控制方式下系统的换相失败免疫因子和换相失败概率指标。In the control system of HVDC transmission,inverter control stage is used to control the trigger phase of converter,and realize constant current,constant voltage and fixed-off angle control on DC side.In current DC transmission project,the control system is mostly based on the control strategy of SIEMENS or ABB,and CIGRE HVDC standard test model is widely used in research of DC transmission due to its simple structure and reference.Therefore,comparing CIGRE HVDC standard test model,SIEMENS and ABB's basic control strategies,and analyzing the system transient performance and commutation failure immunity under different control coordination modes,it plays important role in improvement and perfection of DC transmission test model.Firstly,this paper presents three basic control methods:CIGRE,SIEMENS and ABB.Based on CIGRE HVDC standard test model,control systems based on SIEMENS and ABB basic control strategies are built respectively.The steady state and transient responses of the system under three control strategies are simulated and analyzed.Finally,the system's commutation failure immune factors and commutation failure probability indexes under three control modes are compared.
