面向潮流调控与电能质量治理的混合式柔性合环装置多模态控制策略研究

Hybrid flexible interconnection devices (FIDs) combine the advantages of power electronics technology and electromagnetic interconnection devices in terms of regulation accuracy, overload capacity and economy, which have been favored in engineering applications. Aimed at the problems of power flow control and background harmonics in a hybrid FID under the condition of steady-state interconnection of power grid, as well as the problem of load voltage deviation and harmonic voltage under the condition of power-loss switching, the line power flow and harmonic distribution characteristics under these two operating conditions are analyzed, and the corresponding power flow control and multi-mode power quality management strategies are put forward. In addition, the feasibility of the proposed strategies is verified by simulation results.
