Abstract

Abstract: ±100 MVar high voltage static synchronous compensator (STATCOM) device is used for high voltage DC transmission which needs higher reliability. Faster response for its control system to deal with metal ground fault and other situations is required. Direct Current Control (DCC) can be used for these situations. Quasi- Proportional Resonant (quasi-PR) controller under DCC was studied and its parameters settings were discussed. The calculation methods of key parameters such as K_p and K_r were explained by mathematical deduction process. The STATCOM under higher voltage in Yunnan-Guangxi Funing transaction station was taken as an example for the calculation of its parameters and RTDS simulation. Simulation results indicate that this control method satisfies the needs of less than 10ms response time and has single-phase metal ground fault crossing capability. It has certain practical and engineering value.

Key words: parameters setting, direct current control (DCC), independent phase control (IPC), quasi-proportional resonant control (quasi-PR), RTDS experiment, STATCOM under higher voltage
