摘　　要：小型微电网系统电能智能管理过程中,依靠基础的PID算法对电能计量表进行自动化控制,易受震荡作用影响,导致该控制模式下电能计量表的示值误差较大。因此,该文研究了一种新型小型微电网系统电能计量表自动化控制方法。考虑电能计量表工作原理,运用均值偏移算法实时跟踪计量表运行参数。建立CAN大数据通信协议,实现运行参数和控制指令的高质量传输。以PLC控制思想为核心,结合遗传优化PID整定算法搭建自动化控制框架。再引入多目标优化思想,完成对电能计量表多目标协同自动化控制。实验结果表明:应用新研究方法对电能计量表运行状态进行自动化控制后,远程自动抄表的示值误差不超过±0.5%,满足了电能计量的准确性要求。In the process of intelligent management of electric energy in small microgrid systems,relying on basic PID algorithms for automatic control of electric energy meters is easily affected by oscillation,resulting in significant reading errors in the electric energy meters under this control mode.Therefore,a new type of automatic control method for energy metering meters in small microgrid systems is studied.Consider the working principle of electric energy meters and use the mean shift algorithm to track the operating parameters of the meters in real time.Establish a CAN big data communication protocol to achieve high-quality transmission of operating parameters and control instructions.Build an automation control framework with PLC control concept as the core,combined with genetic optimization PID tuning algorithm.Further introduce the concept of multi-objective optimization to achieve multi-objective collaborative automation control of electric energy metering meters.The experimental results show that after applying the new research method to automatically control the operation status of electric energy meters,the indication error of remote automatic meter reading does not exceed±0.5%,meeting the accuracy requirements of electric energy metering.
