摘要：
The application and development of the SSSC(Static Synchronous Series Compensator) are restricted due to the difficulty of its start-up. A novel SSSC circuit with external charging circuit is proposed, whose charging state and normal operation state are designed as two different working modes. The start-up and shutdown control strategy for SSSC is analyzed in detail based on the proposed circuit, i.e. the bypass switch on the grid side is opened while its current is zero in start-up stage, and closed while its voltage is zero in shutdown stage. Therefore, the power of the grid is stable during the whole start-up and shutdown progress of SSSC. Finally, the proposed start-up and shutdown control strategy for SSSC is verified in the 220 kV Nanjing Western UPFC Project. © 2019, Electric Power Automation Equipment Press. All right reserved.
