摘要
输电线路严重覆冰会给电网造成严重损失。研究了利用配电网中风电、光伏发电、生物发电及储能装置等多能互补能源形式实现配电网过电流融冰,并提出储能装置作为负荷的配置方法;研究了柔性配电网潮流控制的原理和方法,分析了无功潮流和有功潮流的调节特性,相比于无功调节,有功环流引起的融冰电流更大。以南方电网示范工程为案例,验证了配电网中柔性开关转移潮流,发出无功功率实现配电网过电流融冰的调节效果,仿真结果表明在3回馈线之间产生的有功环流和无功环流均可实现过电流融冰。
Severe icing on transmission lines will cause serious losses to the power grid.This paper studies how to use wind power,photovoltaic power generation,biological power generation and energy storage devices in distribution network to realize over-current ice-melting,and puts forward a method of load allocation using energy storage devices;uses flexible switches in distribution network to transfer power flow and generate reactive power to realize over-current ice-melting in distribution network.Simulation results show the effectiveness of the proposed method.
