Problems solved by technology
The traditional user identification device in the station area adopts the power carrier communication method, which has two obvious disadvantages: in the case of the adjacent station substations sharing high voltage, common ground, and common cable trench, it is easy to cause misjudgment because of the crossover of the carrier signal; the power carrier The signal is a high-frequency signal with severe attenuation, and users with long distances and large line interference cannot be recognized
[0008] At present, in the operation and management of the automatic metering collection system, quantitative analysis, real-time monitoring and abnormal alarms are required for the three-phase power consumption balance, line loss calculation and abnormal line faults in the station area. In new application scenarios, faulty nodes and lines cannot be well expressed, making it more difficult to analyze problems

The invention discloses a method for identifying the topology of a station area. The concentrator and other equipment in the station area freeze data, and then the concentrator collects the data of itself and other equipment in the station area. calculate. The method for identifying the topology of the station area provided by the present invention is based on the improvement of the hardware performance of the concentrator, uses the characteristic gradient matching algorithm to identify the ownership of the electrical equipment in the station area, and then uses the time-freeze power accumulation and matching algorithm to carry out the station area use. Electrical equipment topology level calculation, realizes the topology identification of electrical equipment in the power grid station area, and does not require access to other auxiliary equipment, which is conducive to reducing the cost of topology identification in the power grid station area, and can calculate the line loss and problem analysis in real time, and improve operation and management. efficiency.
Description
technical field [0001] The invention belongs to the field of electricity consumption data collection, and in particular relates to a method for identifying the topology of a station area. Background technique [0002] In 2010, the State Grid Corporation of China fully launched the construction of the electricity consumption information collection system for power users. As of 2018, a total of 554 million smart energy meters had been installed in my country, of which 474 million were supplied by State Grid Corporation of China and 474 million by China Southern Power Grid Co., Ltd. 80 million, and the electricity consumption information collection system covers 99.57% of the users in the service area. In recent years, the functions of smart meters have become more and more powerful, and more and more data can be collected, making outstanding contributions to the intelligence of electricity. However, with the development of smart meter technology, the lag of electricity informa...
