  • Abstract Electricity thief causes many countries lots of financial losses every year. Although there are many methods can detect electricity theft, some papers use consumer load profile or load data to detect electricity theft with different algorithm, but history load profile can not determine that consumer is stealing accurately for some cases. One paper proposes a method to use voltage and real power measured by smart meter of advanced metering infrastructure(AMI), and the results of power flow analyses to determine that customers are stealing . However this method can not detect one electricity theft that consumer connect a capacitor in parallel with one phase of three-phase load. This thesis proposes a method to calculate the data measured by two-wattmeter meter, and use that calculated data with the measurement principle of three-wattmeter meter, we can find out true real power of consumer. Comparing with true real power and real power measured by two-wattmeter meter, we can determine customers who have the suspicion of electricity theft. The method has been proven to be applicable by sample system simulations.
