Abstract: In order to realize real-time and multi-dimensional control of substation risk early warning, a substation risk early warning and control system based on edge computing is designed. The sensing layer collects the operation data of substation equipment through the Internet of Things equipment, and transmits the data to the edge layer through the communication between edge equipment and external equipment. After receiving data, edge layer parses the data through the communication protocol to complete data consistency, and packages cloud services downstream data sending to the cloud computing layer. The layer uses cloud computing to compute and analyze substation equipment data and transmit it to the application layer. The application layer adopts support vector machine (SVM) algorithm to establish a risk early warning mechanism, divide the risk data attribute, and obtain warning value. Based on this, the risk situation corresponding to the early warning value is predicted by the logistic regression risk prediction model, and the probability of failure is obtained to complete the substation risk warning. Meanwhile, the early warning results are presented on the visual interface, and the corresponding risk warning is controlled and controlled by the control channel. The test results show that the communication jitter results of the system are all below 15 ms, which can realize the calculation of risk probability, obtain the number of various risk warnings of the substation, have good work energy efficiency, and realize the multi-dimensional risk warning and control of the substation.
Key words : edge calculation;substation,;risk warning and control,;risk warning mechanism;data analysis,;the early warning value

電力系統(tǒng)中用于完成電力能源接收和分配的場所稱為變電站,,由一類和二類設備組成其可完成電網(wǎng)中電壓和電流的變換,按照電壓的等級對其分類,,可將其分為四類,。由于變電站的結構較為復雜,因此電力企業(yè)在對變電站實行管理過程中,,為保證變電站的運行安全,,安全監(jiān)控則是主要手段。并且變電站在安全管控過程中存在突發(fā)性,、未知性,,因此,導致對變電站風險因素的變動趨勢掌控存在一定不足,,其風險預警則產(chǎn)生一定的不確定性,。邊緣計算是一種能夠提供最近端服務的技術,其可在邊緣側發(fā)起應用程序,,實現(xiàn)網(wǎng)絡服務的快速相應,,滿足業(yè)務的實時、智能應用以及安全保護等需求,。

周敬嵩等人和楊至元等人針對變電站安全管控過程中存在的問題,,分別對變電站的安全管控實行分析后,基于移動式紅外測溫,、基于Cyber-net與學習算法分別研究變電站的安全管控方法,。上述方法在管控過程中,僅在變電站設備溫度預警,、故障預警方面具備較好效果,,但是無法完成微小風險的提前預防,,實現(xiàn)多維度風險預警。因此,,本文設計基于邊緣計算的變電站風險預警管控系統(tǒng),,結合邊緣計算和云計算的優(yōu)勢,實現(xiàn)變電站風險預警管控,。
