STABILITY- STUDIES OF A POWER SYSTEM WITH LARGE ASYNCHRONOUS LOADS

Abstract

The importance of Power System load char ao. terietics under transient conditions has been stressed in the literature, but little . information is available particularly regarding frequency dipendence; general c-onditions regarding the behaviour of active and reactive lots components with frequency have been cor sidered and stability studies have been carried out on the Western U.P. Grid. An efforts has been made to c mpare the stability considering the loads to be constant impedence and considering them to be grequency and voltage dependence. A detailed procedure is. developed from considering the voltage dependence and frequency dependence of the loads in trane-ient stability studies of the system.
