A line loss management and control system based on big data

Abstract

A large data-based station line loss management and control system proposed by the present invention includes: a power grid structure data management unit, which is used to construct and maintain the station area structure data and associate it with the meter box T-connected users; an operation data maintenance unit, It is used to import the operation data of the station area and integrate it with the data of the power big data center; the calculation unit of the station area structure data is used to verify the station area structure data and perform batch calculation according to the type of the station area structure data; the loss reduction node optimization unit , which is used to filter out the nodes and line segments to be optimized by analyzing and calculating the structural data of the station area, and optimize the phase sequence of the nodes and line segments; the station area topology map management unit is used to generate the corresponding topology map according to the structure data. ; The visual display unit is used to display the loss data before and after optimization through the topology map. The invention can collect the power consumption data of each line section in the station area, and screen out the lines whose power transmission is blocked, so as to realize the control of the line loss of each line section in the station area.

Description

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

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.
