Power distribution network line operation efficiency evaluation method and device, and storage medium

Abstract

The invention discloses a power distribution network line operation efficiency evaluation method. The method comprises the steps of calculating an optimal load of a power distribution network line andan available load of the power distribution network line according to received historical operation data; and according to the optimal load, available load, calculating a reference load level value and an actual load level value of the power distribution network line respectively according to the rated power of the power distribution network line and the actual load of the power distribution network line; the ratio of the actual load level value to the reference load level value is used as the operation efficiency of the power distribution network line; according to the operation efficiency obtained through calculation, the load value with the minimum loss cost of the power distribution network line in the ideal state is comprehensively considered, the maximum load of the power distribution network line under the standby capacity and the rated load and the actual load of the power distribution network line are considered, and the operation efficiency obtained through calculation can be more accurately evaluated. The invention also provides a power distribution network line operation efficiency evaluation device and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to a method, device and storage medium for evaluating the operating efficiency of distribution network lines. Background technique [0002] With the reform of the power system, the distribution network needs to pay attention to operational efficiency, improve asset utilization and income levels, and maximize the use of existing equipment. At present, the load rate is generally used to reflect the operating efficiency of the distribution network line, and to examine the utilization level of the line. The load rate of the line is generally calculated by the ratio of the maximum current to the rated current. When the load rate of the line is high, the maximum current of the line is large, and the utilization rate of the equipment is high, but the excessive load current will cause the loss of the line. Increase, and at the same time the service life of the line will be red...

AI Technical Summary

Problems solved by technology

The load rate of the line is generally calculated by the ratio of the maximum current to the rated current. When the load rate of the line is high, the maximum current of the line is large, and the utilization rate of the equipment is high, but the excessive load current will cause the loss of the line. increase, and at the same time the service life of the line will be reduced accordingly, so although the utilization rate of the line is improved, it is not economical to reduce the service life of the equipment

And when the load rate of the line is low, the equipment is not fully utilized, and its utilization rate is low

Therefore, the methods for evaluating the operating efficiency of distribution network lines in the prior art cannot integrate multiple constraints, resulting in inaccurate evaluation
