Abstract

Traditional synchronizer cannot control multiple generators in distribution networks in coordination. In this paper, a real-time synchronization control (RTSC) is designed to keep all generators in different standalone distribution networks in synchronization at all times, which realizes a fast and reliable reconnection of disconnected power network. The frequency control and phase control in RTSC are investigated and low-pass filters are properly designed to avoid interference between these two controls. The simulation results in an isolated power system is verified the effectiveness of RTSC and have proved that the transient stability during reconfiguration process can be greatly enhanced by applying RTSC into system-level supervisory control of isolated power system.
