摘要
In order to improve the reliability of 6 kV cascaded STATCOM with LCL filter, the reliability and safety of the system could be improved by using the software tolerance and hardware techniques together. The reliable and stable operation capability could be ensured by reconfiguring hardware structures and software with fault-tolerant control strategies. To realize seamless fusion between fault diagnosis and fault-tolerant control, phase inside voltage balance control and phase to phase voltage balance control strategy of the capacitor and PWM control strategy with fault-tolerant control function were brought into the control framework. The simulation and experiment demonstrate that the platform has good dynamic compensation effects, accurate diagnostic ability, and fine fault-tolerant control performance. ©, 2015, China Coal Society.
