摘　　要：由于大量大功率电机投切以及变频器等非线性设备的使用,使煤矿电力系统时刻处于相对不稳定状态,在相关参数变化的情况下可能产生混沌振荡,而此种振荡状态严重影响系统运行安全。针对这一情况,采用双模糊PID方法进行混沌振荡抑制,其中,模糊控制器参数采用一种量子粒子群算法进行优化。采用滤波器提高控制器稳定性,通过合理选择时间常数,消除了系统存在的小幅振荡,使系统相对角度稳定在平衡点附近,系统相对角速度稳定在零值。此种控制方法具有较好的快速性与稳定性,为煤矿电力系统混沌振荡抑制提供了新思路。Due to the use of a large number of high-power motor switching and frequency converter in power system of coal mine,it is always in a unstable state relatively,and chaos oscillation may occur when the relevant parameters change.It affects the safety of the system operation seriously.In order to solve this problem,a double fuzzy PID method is adopted to inhibit the chaos oscillation.The dual fuzzy PID method is used to suppress chaotic oscillation,and the fuzzy controller parameters are optimized by a quantum particle swarm optimization algorithm.A filter is used to improve the stability of the controller,by selecting the time constant to improve the stability of the controller.The relative angle of the system is stable near the equilibrium point,and the relative angular velocity of the system is stable at the zero point.This control method has good rapidity and stability.It provides a new approach for suppressing chaotic oscillation in power system of coal mine.
