| Abstract: | This paper reports a transient stability and static security control system, which developed for HeNan power grid. The system periodically evaluates the static security and transient stability based on on-line information, which is integrated by state estimation in EMS, the real time actual network data telemetered from control substations, and the typical network operation mode data, selects the optimum generators and load to be shed, accordingly to refresh the control decision tables in two different area control substations every 5 minutes. Field test operation demonstrates the excellent performance of this system. |
