| 摘 要： | 在多馈入交直流混合电力系统中,因为多条直流线路落点于同一交流电网、各换流站间电气联系紧密、无功消耗大,交、直流系统间常以换流母线为纽带发生非常复杂的交互影响。本文围绕多馈入交直流系统的相互影响,概述了换相失败、功角/电压稳定性、扰动后直流输电系统的协调恢复等问题,分析了现有控制和恢复策略的特点及不足,为今后多馈入交直流系统的进一步研究提供依据。

| Abstract: | In multi- infeed AC and DC hybrid power system, due to a number of DC lines fall in the same AC power grid, closer electrical distances among DC converter stations, and large reactivepowerconsumption, there are very complicated interaction influence in the AC and DC system normallybased on the converter bus ties. Around the interactions between multi-infeed AC and DC system, thispaper summarizes the problems of present situation of the research on commutation failure, angle/voltage stability of power system, coordinate recovery of DC system after disturbance, and so on,analyzes the features and defects of existing control and recovery strategies. Provides a reference forthe research of multi-infeed AC and DC hybrid power system in future. |
