摘要
Abstract
In allusion to the case that improper configuration of artificial frequency dead zone of the primary frequency mod-ulation (FM)may influence normal operation of the unit,this paper analyzes characteristics of the primary FM of unit when adopting different types of artificial frequency dead zones respectively according to ordinary mathematical model and en-hanced mathematical model. It also uses regulating system model of the water turbine provided by PSD-BPA transient stabili-ty program for simulation. The results indicate that the enhanced artificial frequency dead zone will not weaken regulating depth of the primary FM and is able to promote response quick-action of FM,but if the setting value of enhanced artificial frequency dead zone is larger and when system frequency frequently fluctuates at the edge of artificial frequency dead zone, load of the unit will fluctuate obviously.关键词
