摘　　要：为了解决多馈入交直流混合系统中诸控制元件之间协调的问题,根据模糊逻辑推理方法与最优分散协调算法,设计了智能模糊分散协调控制器(FODC),从而使整个交直流系统的性能达到最优。用 NETOMAC 仿真软件仿真了一三机双直流系统。仿真结果表明,所设计的 FODC 确实能提高整个交直流输电系统的稳定性,且优于常规的无分散协调控制(NDC)和有分散协调控制(ODC),在不同扰动下亦能表现出很好的适应性。In order to coordinate the control components in multi-infeed AC/DC system, a fuzzy optimal and decentralized and coordinated controller (FODC) is designed by virtue of the fuzzy logic reasoning method and the optimal decentralize and coordination algorithm, and it makes the performance of the whole AC/DC system optimized. A three machine AC/DC system is simulated by NETOMAC software, the simulation results show that the designed FODC can really improve the stability of the whole AC/DC system. The FODC, which is adapted to different disturbances, is better than the conventional no decentralized coordinated control (NDC) and optimal decentralized coordinated control (ODC).
