| 摘 要： | 大容量冲击负荷的生产运行可对邻近电厂的机组安全造成不利的影响。采用EMTP程序作为仿真工具,分析了在EMTP中建立冲击负荷非线性模型并进行冲击负荷对邻近发电机组影响的电磁暂态仿真的可行性。从冲击负荷对机组的影响,尤其是对轴系的暂态扭矩冲击方面,详细地探讨了冲击负荷对机组影响的评估指标,提出了以轴系疲劳寿命损耗和电磁功率变化量指标进行机组轴系扭振影响评估时的准则。通过对实际电网的仿真分析,验证了该准则的实用性和有效性。

| Abstract: | High-capacity impact loads can produce adverse effects on the safe operation of generators at nearby power plants.EMTP was selected as the simulation tool,and its feasibility on non-linear modeling of impact loads and electromagnetic transient simulation for large power system was firstly analyzed.From the aspect of effects of impact loads on generators,particularly,on transient shaft torsional torques,indices for evaluating the effects were discussed in detail,and guidelines for evaluating shaft torsional ... |
