摘要 分析负荷模型对多馈入交直流系统功角稳定性的影响。在远方电源向负荷中心送电的多馈入交直流系统中,受端负荷为动态负荷或恒功率负荷时,系统的功角稳定性差;受端负荷为恒电流负荷,特别是恒阻抗负荷时,系统稳定性较好。同时分析了负荷模型对采用直流简单模型进行快速扫描的精度影响。通过量化分析方法揭示了上述现象的机理。 The influences of load models on transient stability of a multi-infeed DC and AC system are analyzed at length. Dynamic loads and constant power loads at the receiving side make against the stability of such a system, whereas constant current loads and constant impedance loads are helpful for it. The errors introduced by replacing HVDC systems with simplified loads are also discussed in stability assessment under various load models. The mechanisms are explained from a quantitative analysis viewpoint.
