Multifunctional station line loss management system

Abstract

The invention discloses a multifunctional station line loss management system, and belongs to the field of power generation, power transformation or power distribution. The system comprises an existing transformer area digitalization management system, wherein the transformer area digitalization management system reads power supply and sale quantity information of each outgoing line or each user of a transformer substation to compute line loss; a list of line loss rates of the users in a previous month is exported from the transformer area digitalization management system; a line loss distinguishing data model is established to screen high line loss rate transformer areas; line loss data exception transformer areas are locked; the users in the line loss data exception transformer areas are counted according to power quantity differences of the users during flat and peak load periods; and exceptional power utilization periods are automatically distinguished by comparing the power quantity differences during the flat and peak load periods. The system can increase a distinguishing success rate of transformer area/station line loss factors, can progressively improve an integral line loss control level of transformer areas/stations by virtue of a spiral rising working mode, can gradually reduce an integral line loss rate of a regional power supply network, and can be widely applied to the field of operation analysis and power utilization management of power systems.

Description

technical field [0001] The invention belongs to the field of power generation, power transformation or power distribution, and in particular relates to a line loss measurement and management system for measuring and managing user electric energy consumption. Background technique [0002] In the process of transmitting and distributing electric energy, the power loss, electric energy loss and other losses generated by various components in the power network are collectively referred to as line loss (power supply loss), referred to as line loss. [0003] For the urban power supply department, the line loss usually includes all the electric energy loss from the main transformer of the substation to the electric energy meter of the user. [0004] Line loss electricity cannot be directly measured, it is calculated by subtracting power supply and electricity sales. [0005] The percentage of line loss power to power supply is called line loss rate, or line loss rate for short. ...

Problems solved by technology

Due to factors such as age, housing structure, and public area, most of them use old-fashioned meter boxes, and the wiring is not standardized; some old-fashioned communities have many illegal buildings, strong population mobility, serious random connections, and various forms of electricity theft. Concealment, which is also one of the reasons for the high line loss

[0012] Since the distributed station area is a low-voltage distribution station area, and there are many residential households in the low-voltage station area, there are many and scattered powe
