Method, device and storage medium for evaluating line operation efficiency of distribution network

Abstract

The invention discloses a method for evaluating the operating efficiency of a distribution network line, which includes calculating the optimal load of the distribution network line and the available load of the distribution network line according to the received historical operation data, and calculating the optimal load, available load, The rated power of the distribution network line and the actual load of the distribution network line calculate the reference load level value and the actual load level value of the distribution network line respectively, and the ratio of the actual load level value to the reference load level value is the distribution network line Operating efficiency, the calculated operating efficiency comprehensively considers the load value of the minimum loss cost of the distribution network line under the ideal state, the maximum load of the distribution network line under the consideration of the reserve capacity, the rated load and the actual load of the distribution network line, thus The calculated operating efficiency can more accurately evaluate the operating efficiency of distribution network lines. The present invention also provides an evaluation device and a storage medium for the operation efficiency of distribution network lines, 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...

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
