Problems solved by technology

[0003] The existing AC overhead transmission line power frequency electric field simulation calculation can only calculate the power frequency electric field in ideal scenarios (such as the ground is completely level), but in engineering practice, high voltage transmission lines often cross hills, river valleys, buildings, trees, etc. Obstacles, they will have a distorting effect on the power frequency field strength
In the face of the above complex scenarios, the existing calculation and analysis tools cannot meet the needs of actual engineering

Abstract

The invention discloses a power frequency electric field three-dimensional analysis method and system for a complex scene under a power transmission line. The method comprises the steps that a simplified model of the power transmission line complex scene is built for complex three-dimensional characteristics of the complex scene, then, a charge simulation method is adopted for calculating the electric field intensity value of each point in the complex scene, a power frequency electric field distribution diagram is drawn, and therefore technical references are provided for alternating current power transmission line electromagnetic environment evaluation, project planning design and the like in the complex scene.

Description

technical field [0001] The invention relates to the technical field of power grid simulation, in particular to a power frequency electric field analysis method and system in complex scenarios. Background technique [0002] The power frequency electromagnetic field simulation calculation is becoming more and more important in the evaluation and analysis of the electromagnetic environment of the power grid. to social harmony and stability. [0003] The existing AC overhead transmission line power frequency electric field simulation calculation can only calculate the power frequency electric field in ideal scenarios (such as the ground is completely level), but in engineering practice, high voltage transmission lines often cross hills, river valleys, buildings, trees, etc. Obstacles, they will distort the power frequency field strength. In the face of the above complex scenarios, the existing calculation and analysis tools cannot meet the needs of actual engineering. Conten...
