摘要
主要研究了电力系统黑启动过程中的电磁暂态问题,包括发电机自励磁问题、合闸空载线路的操作过电压问题、以及空载线路末端的工频过电压问题。以贵州电网为例,应用电磁暂态仿真软件PscAD/EMTDc建立了电磁暂态问题的仿真模型,分析了贵州电网的黑启动方案。
This paper mainly researches the electromagnetic transient problem of black -start , including self - excitation of generator, over - voltage due to the charge in unloaded lines and power frequency over - voltage in the end of unloaded lines. Taking power grid of Guizhou as the example, it analyzes the black - start scheme of power grid of Guizhou and establishes the emulator model about electromagnetic transi- ent problem and figures out the voltage of different points in power system through the calculating model which is established through the electromagnetic transient emulator , which is PSCAD/EMTDC.
