新能源场站涉网性能验证试验仿真分析

按照新能源场站涉网性能验证试验的考核要求,建立了宁夏香山地区新能源场站的模型,提出了具体的试验方案。并通过仿真计算分析了不同短路试验地点对各新能源场站的考核效果。结果表明:在宁夏香山 330 kV 变电站 110 kV 母线侧香沙 I 线出口进行短路试验可有效考核该变电站汇集的所有新能源场站的涉网性能,达到预期考核目标。

Simulation analysis on the performance verification tests of new energy power stations involved in power grid

According to the evaluation requirement of the performance verification tests of newenergy power stations involved in power grid,establishes a simulation model for the new energypower stations of Xiangshan area in Ningxia,puts forward the test schemes. By the simulationcalculation,analyzes the evaluation effect of short-circuit tests at different locations on every newenergy power station. The result shows that the short-circuit test on the exit of No.1 transmissionline from Xiangshan to Xiangsha by the side of 110 kV bus in Xiangshan 330 kV substation caneffectively assess the performances of the substation to marshal all new energy power stationsinvolved in power grid,achieves the expectant verification purpose.
