Abstract

The invention discloses a power frequency electric field calculation method for a complex scene. The method comprises the following steps: acquiring basic data of the complex scene, modeling and calculating the power frequency electric field of the complex scene by using the basic data, and obtaining an electric field calculation model; using the PCAM of OpenMP parallel algorithm to redesign the charge simulation method, and obtaining the target charge simulation method which is suitable for running in parallel program; calculating the electric field calculation model by the charge method of target simulation, and obtaining the power frequency electric field of the complex scene. Obviously, since the method utilizes the PCAM of the OpenMP parallel algorithm to calculate the power frequencyelectric field of the complex scene in a multi-core parallel manner, and compared with the prior art, the method utilizing the serial mode to calculate the power frequency electric field of the complex scene greatly improves the calculation speed of the power frequency electric field of the complex scene. Accordingly, a power frequency electric field calculation system for a complex scene disclosed in the present application also has the above-mentioned beneficial effects.

Description

technical field [0001] The invention relates to the technical field of power grid environmental protection, in particular to a calculation method and system for a power frequency electric field in a complex scene. Background technique [0002] With the increase of the voltage level in the power grid, the calculation of the power frequency electric field in complex scenarios has become a current research hotspot. Since transmission lines are often erected in complex environments with large undulating terrain and many trees, it is difficult to calculate the power frequency electric field in complex scenes. At present, the calculation of the power-frequency electric field in complex scenes adopts the method of serial calculation, but this method often requires a long calculation time. It can be seen that how to increase the calculation speed of the power frequency electric field in complex scenes is an urgent problem to be solved by those skilled in the art. Contents of the ...
