摘　　要：断电控制系统会受到电流、电压过高的影响,导致控制效果差,提出基于改进遗传算法的高压用户自动断电控制系统。在高压用户自动断电控制系统结构支持下,设计磁保持继电器,借助一定宽度脉冲信号触发开关。使用Type-C型号转换器,匹配输入端仪表和输出端仪表,保证转换过程中信息不会出现畸变现象,完成硬件结构设计。使用改进遗传算法,确定交叉概率、变异概率因子,优化低压减载量,根据设计的控制流程,实现系统自动断电控制。实验结果表明,该系统不会受到电流、电压过高的干扰影响,具有良好的控制效果,确保供电处于不间断状态。The power⁃off control system will be affected by the high current and voltage,resulting in poor control effect.Based on the structure of the automatic power⁃off control system for high voltage users,a magnetic holding relay is designed to trigger the switch with a certain width of pulse signal.The Type⁃C converter is used to match the input and output instruments to ensure that the information will not be distorted during the conversion process,and the hardware structure design is completed.The improved genetic algorithm is used to determine the cross probability and mutation probability factors,optimize the low voltage load shedding,and realize the automatic power⁃off control of the system according to the designed control process.The experimental results show that the system will not be affected by high current and voltage interference,and has good control effect to ensure that the power supply is in an uninterrupted state.
