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

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.
