| As we all know, the power in transmission loss occurs. In the power system, from power generation to power in all aspects of network power transformers, transmission, distribution and other power loss are present. The current power grid enterprises energy loss increasing work requirements, whether technical or management Loss Reduction Loss Reduction, have raised the improvement objectives, including management involves reducing losses to be reduced from Stealing unusual line losses. In the distribution network, the artificial line loss means the phenomenon to stealing has been caused by the presence of repeated investigations without a break. This paper presents a theoretical calculation of line loss and line loss real-time data analysis to determine a method of stealing phenomenon for Stealing new attempt to achieve lower loss purposes.Firstly, the current common collection means stealing, stealing analyze the reasons and motives. Stealing grid enterprises studied techniques and methods to find insufficient current grid enterprise anti-tampering system. It focuses on the under/depressurization method, broken/lost flow method and phase shift method means stealing a circuit diagram to determine the root causes of Stealing technical methods.Then introduces the basic concepts and line loss calculation method theory. Based on the theory and line loss classification line losses, and summarizes the calculation method of load flow algorithm currently used grid companies, rms current method. Nanning Power Supply Bureau in 2013 calculated theoretical line loss, and the calculated value based on the theoretical line loss, analyzed the possibility of stealing high-loss lines.Finally, the paper summarizes work experience, judgment finishing line loss of stealing two methods and practical cases. One is the maximum theoretical line loss calculation method is determined. Real-time energy metering line automation platform in place to monitor the loss of statistical line losses judge, maximum and real time line for Theoretical Line Loss Calculation of loss compares real-time line when a certain percentage of losses exceeds the maximum, then the presence of line losses suspected of stealing a large leak or electrical energy meter situation. Another real-time line loss rate volatility anomaly analysis. When the lOkV line real time line loss in a certain period presented abnormal fluctuations, analyze line load is abnormal, and thus locate the suspects stealing customers.In a recent case investigated four cases of stealing is the maximum theoretical line loss calculation method and determine line loss rate of abnormal fluctuations in real time method to get a better application of typical cases, when the line loss rate exceeds the theoretical maximum or abnormal fluctuations, alarm information, line load analysis by the staff, location stealing suspect. Rely on data analysis system, greatly reducing the workload of the staff, and regain the initiative in changing the past only by reporting against stealing operating mode, effectively monitoring the daily line losses go into work Stealing enhance the lean management level grid companies. |
