Abstract:Aiming at the problem of electricity theft seriously hindering the establishment of a fair and reasonable user order,An anti-theft system that combines adaptive weighted fusion algorithm and deep belief network (Deep Belief Networks, DBN) learning algorithm is proposed based on Smart power system big data processing platform in cloud environment (SP-DPP),big data is processed by using DBN layer-by-layer greedy training algorithm, and a DBN deep learning algorithm is constructed by using the double-layer RBM structure, which can normalize the acquired electricity metering information and convert the acquired macro high-latitude data information into low-latitude data that is easy to identify and calculate. Tests show that the algorithm of this study has high recognition rate and good stability.

窃电是指一些违法分子在供电或者用电期间,采用隐秘的盗窃手段非法使用电能,最终以很少的成本用电,或者无成本用电。在电力经济技术发展的不断推动下,各个行业都离不开电能,在人们生活和企业生产过程中具有举足轻重的作用。因此,如果存在窃电行为,不仅给配电公司带来巨大的损失,也会由于窃电手段造成配电线路处于高危险状态,严重时,会导致漏电、失火,设置会危害人们的生命。因此,打击窃电行为、防止窃电是建立公平、安全的用电行为的重要手段。

现有技术中,如文献[1]虽然在表计及电路的原理上进行了改进,但是这手段仍旧是在改变电能表或者电能计量设备的硬件结构形式来防止窃电,这种方式虽然在一定程度上避免了窃电行为,但很难及时获取窃电信息,防窃效率不高[1]。……
