摘要/Abstract

摘要： 针对特高压直流系统(LCC-HVDC)系统中易发生连续换相失败的问题，提出了一种非线性动态电流偏差控制方法。该方法依据交流故障严重程度动态调整电流偏差控制运行曲线，并利用非线性曲线代替原一次线性曲线，提高熄弧角增量对电流偏差的灵敏度，增大实际熄弧角裕度，进而有效抑制直流系统连续换相失败。PSCAD/EMTDC仿真表明，所提方法能有效抑制各种类型故障导致的连续换相失败，利于故障后直流系统的快速恢复。

关键词: 特高压直流, 连续换相失败, 电流偏差控制, 熄弧角, 故障恢复

Abstract: Aiming at the continuous commutation failures in LCC-HVDC systems, a nonlinear dynamic current deviation control method is proposed. The operation curve of current deviation controller is dynamically adjusted according to the severity of AC faults. Meanwhile, the nonlinear curve is used to replace the original linear curve to improve both the sensitivity of extinction angle increment to the current deviation, and the actual extinction angle margin, thus effectively suppressing the commutation failures of DC systems. The simulation results in PSCAD/EMTDC show that the proposed control method can effectively suppress the continuous commutation failures caused by various faults and can help the rapid recovery of DC system after faults.

Key words: ultra high voltage direct current(UHVDC), continuous commutation failure, current deviation control, extinction angle, fault recovery
