摘　　要：在大区电网通过交流互联的趋势下,电网规模日益增大,电网理论计算分析数据量、数据规模海量增加,数据误差的大量累积造成数据分析结果可能出现偏差,为解决电网规模与计算时间、速度之间的矛盾,减少数据误差,计算误差带来的不利因素,需对电网计算数据进行有效而实用的等值。针对新疆电网连入西北电网海量数据的增加,为增加计算精度、缩短计算时间,减少计算误差,就网络等值化简方法进行了综述,并在此基础上对即将与西北主网联网的新疆电网进行了等值,并就等值前后的稳定计算进行了对比,并就误差做了分析,得到了相应结论。The interconnection of the large-area power grid has increased its scale.In order to solve the conflicts between the scale of the grid and the computing time,the effective and practical equivalence is the only solution.The grid equivalence methods are summarized.Based on the summarization,the equivalence of Xinjiang Power Grid which is about to interconnect with the Northwest Power Grid is carried out,and the results of stability calculation before and after the equivalence are compared.Then the error has been analyzed to obtain the corresponding conclusion.
