对低负荷期间降低变压器损耗、防止过励磁的分析与实施

辽阳电网负荷变化季节性特点明显,春夏秋季处于高峰负荷期,冬季处于低谷负荷期。为提高电网运行经济水平、防止系统电压超限,科学安排电网方式,本文从220千伏襄平变着手,技术角度分析如何解决低谷期降低变压器损耗、防止过励磁的措施,旨在为提高电网安全运行水平提供参考。

The Analysis and Implementation for low load Period to Reduce Transformer loss and Prevent the over Excite

The seasonal characteristic of the changes in Liaoyang power grid load is obvious,the peak load period is spring, summer and autumn, winter is off peak load period. In order to improve the power grid to run the economy level, prevent the system vohage limit exceeded,In a scientific way to arrange the power grid, this article start from 220000voh change for Xiang Ping, Analysis of how to solve the low period to reduce the loss of the transformer from the technical point of view, prevent over excite, in order to provide reference for improve the level of safe operation of power grid.
