District line loss management and control system based on big data

Abstract

The invention provides a transformer area line loss management and control system based on big data, and the system comprises a power grid structure data management unit which is used for constructing and maintaining transformer area structure data, and carrying out the association with a meter box T-connection user; an operation data maintenance unit which is used for importing the operation data of the transformer area and fusing the operation data of the transformer area with the data of the power big data; a transformer area structure data calculation unit which is used for verifying the court structure data and performing batch calculation according to the category of the court structure data; a loss reduction node optimization unit which is used for screening out to-be-optimized nodes and line segments through the analyzed and calculated transformer area structure data and performing phase sequence optimization on the nodes and the line segments; a transformer area topological graph management unit which is used for generating a corresponding topological graph according to the structural data; and the visual display unit which is used for displaying the loss data before and after optimization through a topological graph. According to the invention, the power consumption data of each line section in the transformer area can be collected, and the line with blocked power transmission can be screened out, so that the line loss of each line section in the transformer area can be managed and controlled.

Description

technical field [0001] The invention relates to the field of intelligent decision-making of electric power data monitoring, and more specifically relates to a line loss management and control system based on big data. Background technique [0002] Line loss not only affects the economic benefits of power supply enterprises, but also causes a waste of social energy. It reflects the planning and design, production technology and operation management level of the regional power network. In recent years, the compliance rate of line loss in the station area has become one of the important indicators for the evaluation of the level of governance of power supply enterprises. [0003] After the reconstruction according to the normal plan, the theoretical value of the line loss rate of the station area should be below 4%, but it is found through statistics that the line loss rate of the transformed station area is still more than 30%. In the process of high-loss station area governa...

AI Technical Summary

Problems solved by technology

In the process of high-loss station area governance, power supply stations often only start from the management direction, while ignoring the impact on the technical level. The main reason is that the technical improvement level involves complex topological structures of low-voltage station areas, a large number of marketing systems, and collection systems. PMS system and other data support, the power supply station is helpless in the face of problems such as complex calculations and large amounts of calculations

In addition, the marketing system and acquisition system lack the important field of T-connection phase sequence for low-voltage customers, which requires a large amount of data mining calculations, which cannot be completed by the power supply station itself.
