摘要
运用ETAP软件,对某孤立小电网进行了仿真分析.结果表明:大容量电动机的启动虽未造成该电网失稳,但其直接启动的电流较大,给电网带来很大冲击.在光伏电站投入运行前,建议进行电动机启动实验,并根据实测数据进行保护整定或采取电动机启动措施减小压降.
By ETAP software, simulation and analysis is made to the isolated small power grid with photovoltaic. The result shows that though the large capacity motor starting will not cause the power gr/d instability, the direct starting current is often large, which will cause great impact on the grid. Before the photovoltaic power station is put into operation, it＇s advisable to do motor start experiment, go on protection setting according to the measured data or take measures to reduce the motor start voltage drop.
