[Abstract]:With the development of economy and the improvement of people's living standard in recent years, the number of electric power users in our country is more and more, which makes the challenges faced by power supply enterprises increase year by year. On the one hand, because of the increase in the number of electricity users, it will inevitably increase the workload of meter reading in the power sector by a large margin. On the other hand, the period of time spent on load electricity will increase, and the power production pressure will increase. The demand for planned dispatch and economic dispatch is also increasing, which highlights the contradiction between power supply and demand. In order to solve the contradiction between supply and demand, improve customer satisfaction, realize peak and valley cutting and scientific and reasonable electricity consumption, a power information collection system with real-time meter reading, checking and monitoring, and demand side management functions emerges as the times require. The power information acquisition system can monitor and monitor the power scene in real time and carry on the on-line inspection to the electricity field, realize accurate data reading and reading, and can guarantee these data to get timely, accurate transmission at the same time, In this way, the management of the on-site watt-hour meter by the monitoring center can be more convenient, fast, and greatly improve the working efficiency, in order to achieve the purpose of optimizing the whole system, to realize the optimal allocation of resources, and to save manpower, material resources and financial resources by a large margin. It also provides a practical and effective method for enterprises to reduce cost, improve customer satisfaction and improve economic efficiency. According to the actual demand of the development of smart grid, this paper will analyze and apply the power information system of village residents and non-residents within the jurisdiction of Hancun Power supply Station of Mancheng Power supply Company. The line loss analysis function and load monitoring function of advanced application module are tested and analyzed. The main works of this paper are as follows: (1) first of all, the situation of remote meter reading at home and abroad is analyzed. According to this situation, the functional requirements of the electric power acquisition system are analyzed and defined. According to the function Standard of Electric Power user Power Information Collection system and the actual situation of Hancun Power supply Station in Mancheng District, the overall structure of the power acquisition system is designed. The key technology of the electric power acquisition system is analyzed. (2) the communication channel of the electric information acquisition system is analyzed. The communication channel of electrical information acquisition system can be divided into two parts: remote communication channel and local communication channel. The communication channel between the master station system and the acquisition terminal is a remote communication channel. The remote communication technology includes GPRS wireless public network / CDMA wireless public network medium voltage power line carrier and so on. The communication channel between each acquisition terminal or between the acquisition terminal and the intelligent meter is called the local communication channel. The local communication technology generally includes the low voltage power line carrier RS-485 bus. (3) the main business of the power information acquisition system is analyzed and the interactive interface is displayed, the main station software is tested, and the application of the line loss analysis module is analyzed. Help electric power enterprise to find out the source of abnormal line loss, make adjustment in time, reduce line loss; use load analysis module to monitor abnormal load, quickly find fault point or find out the power stealing user, and recover the power supply enterprise loss. The test results show that the application of the electric information acquisition system not only solves the drawback of the traditional meter reading mode which consumes a lot of manpower and material resources, but also improves the accuracy of meter reading and reduces the line loss. It greatly improves the economic benefits and customer satisfaction of Hancun Power supply Station in Mancheng.
