摘要
随着京能新能源公司风力发电装机容量迅速增扩,向系统输送容量明显增加,而系统短路容量亦成倍增长,这给向测量仪表和继保装置供电的电流互感器带来诸多隐患和危害。文章根据电网短路电流特点,提出了电流互感器动稳定和热稳定的优化计算。
With the installation of the wind power generation in Jingneng New energy Co.,Ltd.grows rapidly,the volume transported to system increases significantly,and the capacity of system short circuit also increases twofold,which brings a lot of hidden trouble and harm to the current transformer that provides power to measuring instrument and relay equipment.According to the features of the short-circuit current in power grid,this paper puts forward the optimization calculation of the dynamic stability and thermal stability of current transformer.
