ELECTRICITY THEFT DETECTION SCHEME USING ENERGY LOSS AND VOLTAGE ESTIMATION IN DISTRIBUTION NETWORK

Electricity theft is a notable aspect of power distribution utilities due to increase in the non-technical loss. It results in to imbalance between power supply and demand. Its consequences are over loading of the distribution network and extraneous tariff invoked on legally connected consumers. The advance metering infrastructure is useful for an energy audit of every distribution transformer with the help of communication facility. However, direct hooking on distribution overhead lines or tapping from underground cables remains an interminable issue which has to be rigorously decimated. The objective of this study is to detect real-time power stolen by illegal consumers and identifying the pilferage locations. The proposed scheme is implemented in IEEE 33 bus distribution system and satisfactory results are obtained suggesting that the proposed scheme works satisfactorily under diversified operating conditions.
