Research And Design On Preventing Electricity-stolen Remote Monitoring And Control System

In our country, with the development of the market economy, the increasingly serious phenomenon of power theft and diversification, How to improve the power technology, effectively curb the power theft, has long been a power supply enterprise are concerned about the problem. Power to the power supply enterprise, national economic loss is huge, and the power work is a long-term and complicated system engineering. In this paper, the preventing electricity-stolen remote monitoring and control system design, and makes a detailed study on the test. Theoretical analysis and simulation experiment showed that preventing electricity-stolen device can for power supply system is reliable, accurate and fast in a variety of power theft phenomenon judgment, and for each power has a detailed power record.Based on the analysis of the causes of power, the characteristics of power theft, common power technique, etc, on the basis of the preventing electricity-stolen the overall structure of the remote monitoring and control system of power and network function aspects are studied, and preventing electricity-stolen remote monitoring and control system design scheme is given. Using the data from power management terminal collecting data collector, within a certain time to calculate the primary side of average power SI, read through the RS485 bus multi-function watt-hour meter data at the same time, calculate the average power of the secondary side corresponding time S2. When the sum of S2 and poor value is still less than S1, terminal discriminant for electricity, and real-time active reporting information to the marketing automation system or send text messages to relevant personnel.According to the scheme of preventing electricity-stolen remote monitoring and management system technology, complete the function of data acquisition unit design and receiver function design and power management terminal function design. At the same time preventing electricity-stolen remote monitoring and control system of peripheral hardware circuit design and electronic watt-hour meter which has the function of preventing electricity-stolen technology was improved, in electronic watt-hour meter a critical part of a detailed analysis to MCU to make use of the C language for software programming, and made a corresponding preventing electricity-stolen improve the software part.The system in a company for pilot run, good test results were obtained. Through experimental testing, confirmed that can effectively find various kinds of power theft, the desired effect.
