摘要

本文提出了一种利用模糊逻辑设计高压直流输电线路补充稳定控制器的新方法。模糊控制器使用模糊隶属函数将重要的和可观察的变量，如发电机转速及其速率和发电机的变化率与整流电流调节回路的控制信号联系起来。这些变量使用推理的组合规则来评估控制规则。模糊控制器相当于一个非线性PI控制器，其增益根据误差及其变化率进行调整。通过对与弱交流电力系统相连接的直流输电链路在瞬态扰动下的仿真研究，验证了所提控制器的有效性。

An adaptive fuzzy logic controller for AC-DC power systems

The paper presents a new approach to the design of a supplementary stabilizing controller for a HVDC transmission link using fuzzy logic. The fuzzy controller relates significant and observable variables like speed and its rate of the generator speed and its rate of change of the generator to a control signal for the rectifier current regulator loop using fuzzy membership functions. These variables evaluate the control rules using the compositional rules of inference. The fuzzy controller is equivalent to a nonlinear PI controller, whose gains are adapted depending on the error and its rate of change. The effectiveness of the proposed controller is demonstrated by simulation studies on a DC transmission link connected to a weak AC power system and subjected to transient disturbances.<>
