Abstract: The customer side electricity stealing behavior not only causes the massive loss of power resources, but also causes the overload of line load, leading to fire and other major safety accidents. Aiming at the diversity and concealment characteristics of the current electricity stealing behavior in the side toilets, the key technologies of situation awareness and intelligent early warning of electricity stealing on the customer side are studied for the purpose of restraining the electricity stealing behavior on the customer side. Considering the diversity and concealment of customer side power stealing behavior, six customer side power stealing situation awareness indicators are selected, including rated voltage deviation, voltage imbalance rate and current imbalance rate,etc. The RBF neural network is used to build the customer side power stealing situation awareness model. The selected six indicators and related data are used as the model inputs, and the dynamic K-means clustering algorithm is used to optimize the model. The output of the model is the customer side power stealing situation awareness result. Based on the sensing results, intelligent early warning is realized by sound light alarm device and intelligent device. The experimental results show that the technology can effectively suppress the customer side electricity stealing behavior.
Key words : customer side;electricity theft;situation awareness;intelligent early warning;perception index

    作為一種重要的能源,電能既普遍應用于人們日常生活與工作中,又對社會經濟發(fā)展與國防安全產生直接影響[1]。在科技飛速發(fā)展與能源格局改變的大環(huán)境下,提升能源利用率與電能傳輸的安全性、可靠性是當前電力行業(yè)關注的重點目標[2]。電能的損失不僅是由于電網線路內的電阻與設備轉換造成的,客戶側竊電同樣是電能損失的主要途徑[3]?,F(xiàn)實生活中,客戶側端用電設備的顯著提升令電能的消耗也顯著提升,部分客戶為“節(jié)約成本”紛紛利用不同方式實施竊電行為,造成電能資源大量流失,嚴重制約了我國電力產業(yè)發(fā)展的穩(wěn)定性[4]。同時,客戶側為實施竊電行為,私自改造電路,令電網內產生嚴重線路負荷過載的問題,這些問題極易導致火災等重大安全事故[5]。針對當前具有多樣性與隱蔽性特性的竊電方法[6],研究一種有效的客戶側竊電態(tài)勢感知智能預警關鍵技術具有重要意義。
