本文亮点

An intelligent coordinated startup control strategy is proposed to solve the problem of energy shock affecting the normal startup of multi-terminal direct current (MTDC) transmission system. The substation adopts modular multilevel converter (MMC), in the process of pre-charging MMC, there exists the problem of pre-charging "first-mover advantage" . For this reason, the pre-charging and coordinated startup model of five-terminal MMC-MTDC system was built. Based on the analysis of several typical MMC-MTDC system failures, the intelligent fault recovery and quick startup control strategy was proposed. The simulation results show that: The proposed control strategy can effectively reduce the transient energy impact during startup, and the field test results are consistent with the expected results.
