Abstract In UHVDC transmission project, the main function of the station control system is to control and monitor the circuit-breaker, switch and ground switch in the station, and to operate interlocking of related equipment, which is of positive role to the security and stability of power system. A case study is made on the circuit-breaker reclosure in Jinbei-Nanjing UHVDC Project. Then the reason of circuit-breaker reclosure is analyzed, an software optimization scheme is proposed and corresponding software programs is developed. The experimental results show that the optimized the station control system is normal and have function of anti-trip, and the system running stably and reliably.
