摘要
Abstract
Undervoltage load shedding(UVLS),one of the stability control means in the third line of grid defense system,can effectively and economically prevent voltage from collapsing.Taking Xuancheng area grid in Anhui province as an example,the paper studies a scheme of UVLS based on P-V curves.By stability calculation and analysis,the scheme finds the potential voltage collapse status of the grid,calculates the P-V curves of its certain load nodes and divides these nodes into different configuration clusters according to the quantitative relationship between load growth and voltage reduction,and effectively prevents the voltage from deterioration.In this way,the UVLS schemes can be drafted for each node or area according to their sensitivity of voltage to load,and thus are better in favor of the recovery of system voltage than an unified configuration schem.关键词
