Embodiment Construction

[0047] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0048] The traditional method is based on probabilistic neural network for comprehensive evaluation of power quality. However, the training process of probabilistic neural network is complex, it needs to be re-learned for different topologies, and requires very detailed historical data, which will take a lot of time, resulting in low efficiency of power quality assessment.

[0049] In order to solve the above technical problems, a power quality evaluation method is proposed.

[0050] The power quality evaluation method provided in the embodiments of the present applic...

Abstract

The invention relates to an electric energy quality evaluation method and device, computer equipment and a storage medium. The method comprises the following steps: obtaining a pre-constructed power quality evaluation system corresponding to a to-be-evaluated area; acquiring evaluation index data of a plurality of monitoring points in the to-be-evaluated area according to the power quality evaluation system; performing normalization processing on the evaluation index data to obtain standardized index data; performing combined weighting calculation on the standardized index data to obtain a combined index weight corresponding to the standardized index data; and comprehensively evaluating the combined index weight and the standardized index data to obtain a power quality evaluation result of the to-be-evaluated area. By adopting the method, the time complexity of power quality evaluation can be reduced, and the power quality evaluation efficiency is improved.

Description

technical field [0001] The present application relates to the field of electric power technology, and in particular, to a power quality evaluation method, apparatus, computer equipment, storage medium and computer program product. Background technique [0002] With the rapid development of modern power systems, and in order to stably use green and environmentally friendly renewable energy power generation technology, the distribution network has been connected to large-scale distributed power sources, and the number of nonlinear loads is also increasing. The problem has become the primary task of improving the power consumption of users on the grid side. In addition, the large-scale integration of modern power electronic equipment and high-precision instruments has led to further deterioration of power quality problems in the power grid, aggravating the contradiction between the supply and demand sides of the power grid, and thus causing additional economic losses and loss o...
