基于末端融合的供电服务电压风险预警管控技术研究

Research on Early Warning and Control Technology of Voltage Risk of Power Supply Service Based on Terminal Fusion

当前电压风险预警技术由于末端之间较为独立、电压信号处理关联性不大,导致存在风险预警精度低、稳定性差的问题。为此提出一种新的基于末端融合的电网供电电压风险预警管控技术。供电末端分为首、中、尾3个子末端,子末端分别由STC89C52单片机、电压传感器以及RT12864液晶显示屏组成,在此基础上,通过A/D转换器将电压信号转换为电信号传输到末端。建立回归树,构建供电服务中电压风险预警模型。实验结果表明,所提技术下风险预警精度高且风险预警过程更为稳定。

The current voltage risk early warning technology has the problems of low precision and poor stability due to independence between terminals and little correlation in voltage signal processing.To this end,this paper proposes a new technology of power supply voltage risk early warning management and control based on terminal fusion.The power supply terminal is divided into three sub-terminals:the first,the middle and the last.The sub-terminals are composed of STC89C52 single chip computers voltage sensors and RT12864 LCD screens respectively.On this basis,the voltage signal is converted into electric signal through A/D converter and transmitted to the end.The regression tree is established and the voltage risk early warning model in power supply service is constructed.The experimental results show that the proposed technology has high risk early warning accuracy and its risk early warning process is more stable.
