高耗能负荷对杨庄变电站运行产生的影响及对策

Probe into Influence of High Energy-consuming Load to Yangzhuang Substation and its Solutions

近年来,高耗能铝业电解负荷在电力系统愈来愈多,这类负荷是一种典型的非线性负荷,其谐波及低功率因数已经对电网的安全运行造成了较大的影响。通过渭南电网一座110 kV变电站所带此类负荷对该地区电网的影响进行多角度的分析和计算,提出了解决办法及实施方案,为今后供电系统对这类用户入网审核及入网后的运行管理提供警示和借鉴作用。

Nowadays,the number of aluminum electrolytic high energy-consuming loads is increasing apparently.The aluminum electrolytic high energy-consuming load is a typical non-linear load and its harmonic ＆ lower power factor threatens the safety of power grid running.The paper analyzes the impact of high energy-consuming load to the power grid running from several angles based on a example of 110 kV substation of Weinan power grid,then gives the countermeasures and implementing program,which is much help for audit of the high energy-consuming load assess to the power grid and the management of the loads.
