Abstract

This paper focuses on the transient stability analysis and enhancement evaluation of an actual cogeneration plant. The cogeneration system is constructed in the ElectroMagnetic Transient Program (EMTP) environment for analyses. Simulation results show that the needed CCT curves for successful grid-disconnection operation are much lower than calculated CCT curves without executing grid-disconnection operation. Therefore, three schemes including installations of power factor correction capacitor, static var compensator (SVC) and static synchronous compensator (STATCOM) for enhancement of grid-disconnection operation are studied, respectively. Simulation results are given and discussed.
