摘要
近年来220 kV变电站采用低压侧10 kV向用户直供负荷的供电方式得到推广,随之带来的是主变低压侧进线设备存在工作电流大、短路水平高、造价和损耗高等现实问题造成选型较为困难.本文分析了存在的问题,并提供了一种基于LSTM的电能质量监测模型,并就设备选择策略给出了几种可行的解决方案.
Abstract
In recent years,the power supply method of 220 kV substations using 10 kV on the low-voltage side to directly supply loads to users has been promoted,which has brought about practical problems such as high working current,high short-circuit level,high cost and loss of the low-voltage side incoming equipment of the main transformer,making selection more difficult.This article analyzes the existing problems and provides several feasible solutions.
