风电大规模集中并网下无功补偿计算
|
摘要
电力系统的安全稳定运行很大程度上受无功补偿和无功平衡的影响。针对甘肃河西地区风电场集中并网导致局域电网电压剧烈变化的现状,在甘肃河西地区风电场无功补偿现状的基础上,在电力系统综合分析程序(PSASP)中对大规模风电接入电网后安全稳定性进行了计算,根据计算结果对实际风电场无功补偿容量及运行效果进行了研究,对建议运行方式和不建议运行方式进行了讨论,提出了风电接入电网后稳定水平提高的建议和措施。
The safe and stable operation of power system affected by the reactive power compensation and reactive balance to a large degree. In this paper for the present situation of Gansu Hexi area wind farm centralized grid lead to local power grid voltage radical changes, on the basis of Gansu Hexi area wind farm reactive power compensation, In the power system comprehensive analysis program(PSASP) calculate the stability of safety after the large-scale wind power connected to the electricity grid. According to the calculation results, the actual reactive power compensation capacity and operation effect of wind farm are studied, and the recommended operation mode and the non-recommended operation mode are discussed, the stability level of wind power grid connection the suggestions and measures are put forward.
