摘要

为抑制高压直流后续换相失败,研究系统恢复时电气量与控制量的动态响应,提出引起后续换相失败的主要原因是恢复过程中,故障后换流母线电压处于跌落状态,逆变侧实际触发角存在超调现象,直流电流持续上升,三者共同作用导致系统换相能力不足,无法完成换相过程中阀臂电感能量的转移.为此,提出一种考虑系统恢复过程换相能力的后续换相失败抑制策略,通过限制触发角超调时的直流电流,增大系统换相能力,抑制后续换相失败,以实现直流系统的有效恢复,并在仿真软件PSCAD/EMTDC中利用高压直流标准模型CIGRE Benchmark对所提理论进行了测试与验证.

Abstract

In order to suppress subsequent commutation failures of high voltage direct current (HVDC), the dynamic process of electrical and control quantities during system recovery is studied, and the main reason for subsequent commutation failures is proposed in the paper. During the recovery process, the voltage of the converter bus after the fault is in a state of drop, the actual firing angle of the inverter is in overshoot, and direct current continues to rise. These factors result in an insufficient system commutation capability to complete the transfer of valve arm inductance energy during the commutation process. A suppression strategy for subsequent commutation failure considering the commutation capability of the system recovery process is proposed. By limiting the direct current (DC) when the firing angle is in overshoot, the system commutation capability is increased, and subsequent commutation failures are suppressed. In addition, the DC system is effectively recovered. The proposed theory is tested and verified based on the HVDC CIGRE Benchmark in PSCAD/EMTDC.

Key words： high voltage direct current (HVDC); subsequent commutation failure; recovery process; commutation capability
