Problem diagnosis and planning scheme automatic generation method for transformer-to-transformer distribution

Abstract

The invention relates to power supply analysis, in particular to a problem diagnosis and planning scheme automatic generation method for transformer area transformer areas, which analyzes the relationship between transformer area current problems and reasons, constructs a transformer area current problem identification rule base, and automatically identifies the transformer area current problems by using the transformer area current problem identification rule base and operation data. Based on an equipment master-slave tree structure, attributing the current situation problems and reasons of the transformer area to specific equipment, further forming a power grid transformation demand according to the current situation problems, reasons and equipment of the transformer area, performing deduplication and overall planning on the power grid transformation demand, predicting the load of the transformer area, and calculating a load center point; analyzing a low-voltage power supply point, performing path planning on a low-voltage line, analyzing a medium-voltage power supply point, performing path planning on a medium-voltage line, and performing three-phase home-entry calculation; according to the technical scheme provided by the invention, the defects that the current situation problem of the transformer area cannot be effectively analyzed and an optimization scheme cannot be provided for distribution of the transformer area in the prior art can be overcome.

Description

technical field [0001] The invention relates to power supply analysis, in particular to a method for diagnosing problems and automatically generating planning schemes related to station divisions. Background technique [0002] Judging from the actual situation at this stage, the overall technical level of the agricultural distribution network is relatively low, and the structure and layout are not scientific enough, such as unreasonable line distribution, large operating load, frequent equipment failures; transformer capacity does not match the demand, resulting in The load and line loss are too large; the three-phase load balance problem makes the voltage drop, the transformer overheats, and the line loss increases; the line overload operation increases the reactive power of the agricultural distribution network, and high-order harmonics appear. [0003] Rural distribution network project management lacks effective technical means to support the current status and developme...
