【摘要】 在换流站两侧传统的P-I型电流调节器、电压调节器基础上分别引入辅助控制变量,该辅助控制变量由模糊逻辑控制器生成。用传统控制与模糊控制分别对三机系统进行的仿真结果表明,与传统控制方法相比,当交流系统受到扰动后,模糊逻辑控制能改善换流站直流电流的恒定性,而且提高了交直流系统的暂态稳定性。更多还原

【Abstract】 On the basis of traditional P-I type of current regulators and voltage regulators at both sides of converter substations a kind of auxiliary control variables generated by fuzzy logical controller is added. The simulation for 3-machine system is carried out by traditional control method and fuzzy control method respectively. The simulation results show that compared with traditional control method when AC system is disturbed, the fuzzy controller can improve the steadiness of DC current in converter substation and the transient stability of AC-DC system is enhanced too.更多还原
