摘要:
直流电压稳定是关系到电压源型直流输电系统可靠运行的关键问题之一.为了确保电压源型直流输电系统在一侧换流器故障时仍能有效控制直流电压,在分析电压源换流器在不同控制模式下的外特性的基础上,提出了采用基于直流电压下垂控制的直流电压控制策略.控制器采用该策略后,能实现有功功率控制模式与直流电压控制模式之间的自动转换,确保定直流电压控制的换流站故障退出后,输电系统仍能有效地控制直流电压.最后以一个两端系统为例进行仿真验证,结果表明系统获得良好的动态性能.
Abstract:
DC voltage stability is one of the key issues for reliable operation of voltage source converter based HVDC system.In order to ensure that the voltage source converter based HVDC still can effectively control the DC voltage under one side's voltage source converter being fault condition,the performance of the VSC under deference control mode is analyzed,and then the DC voltage droop control strategy is proposed for VSC based HVDC system in this paper.This approach can realize automatic switching between active power and DC voltage control models,so that control of DC voltage can still be realized after fault and dropping of the converter which is in DC voltage control model.Simulation results show that reliability of the VSC based HVDC system is improved with the proposed control strategy and satisfying dynamic characteristics can be obtained.
