Dynamic Reactive Compensation Device Models for Electromechanical Transient Simulation in PSS/E

This paper introduces in detail the models of reactive dynamic compensation devices in PSS/E developed by PTI Inc.,USA.PSS/E provides SVC models including CSVGN1,CSVGN3,CSVGN4,CSVGN5,CSVGN6 and CSSCST,as well as STATCOM models including CSTATT and CSTCNT.Then these models are applied to the calculation of electrome-chanical transient simulation on a 4-generator,2-area system to illuminate how the SVC models and STATCOM models are employed by PSS/E,at the same time the calculation results show that reactive dynamic compensation devices play an important role in maintaining voltage.
