Abstract

The embodiment of the invention discloses a power distribution network voltage evaluation method, system and equipment, and a storage medium. The method comprises the steps: obtaining electrical element parameters, an electrical topological connection relation and a tower position number from a power distribution network GIS model; generating a model file corresponding to the OpenDss simulation software according to the electrical element parameters and the electrical topology connection relationship in the GIS model; calling the OpenDss simulation software to carry out power distribution network load flow calculation on the model file; and comparing the load flow calculation result with a set power distribution network allowable normal operation value to obtain a power distribution network voltage evaluation result. The GIS model and the OpenDss simulation analysis software are combined, universality is achieved, parameter modeling analysis is directly obtained according to the GIS model, the problem that the voltage evaluation workload is large under the multi-scene condition can be solved, and meanwhile the problems that due to the fact that commercial software is adopted, investment is large, and the professional level requirement is high are solved.

Description

technical field [0001] The present application relates to the technical field of voltage evaluation, in particular to a distribution network voltage evaluation method, system, device and storage medium. Background technique [0002] Due to the development of the economy, the people have increasingly stringent requirements on the quality of power supply. For example, when the power supply is supplied by the distribution network, the high or low voltage will affect the user experience and the normal operation of the equipment, and may even damage the equipment, affecting the user's satisfaction with electricity. Spend. Moreover, in the process of power grid construction, the focus and investment funds are mainly placed in economically developed areas, and insufficient attention is paid to economically underdeveloped areas, especially remote areas such as rural power grids. As a result, there are many problems in the construction of power grids in these areas, such as: power su...
