摘要
备自投投切失败进入孤岛运行方式小水电会对电气设备带来潜在的影响。利用PSASP软件建立了含有小水电的典型系统,分析了采用不同的发电机模型分别进行不同负荷水平、负荷功率因数、不同系统调节参数等情况下孤岛运行模式下的典型特征参数的变化规律;并提出小水电孤岛运行方式切机、切负荷、重新并网的控制策略,最后仿真验证了所提控制策略的有效性。
The micro-hydropower entering into island operation mode due to switching failure will bring some potential influence to the electrical equipment. In this paper, the typical system including microhydropower is set up by PSASP software, different generator modules are used to analyze the variation rule at such typical situation as different load, power factor and different system adjustment parameters at island operation mode, then the control strategy of the micro-hydro power island operation mode in the field of unit switching, load switching and re-networking is proposed. Finally, the effectiveness of the proposed control strategy is verified by the simulation.
