Method and system for calculating synthetic electric field of house platform adjacent to direct current transmission line

The invention relates to a direct current transmission line adjacent house platform synthetic electric field calculation method and system, and the method comprises the steps: determining a simulation charge arrangement mode in each house platform simplification model, and building a direct current transmission line adjacent house platform synthetic electric field calculation method library for all house platform simplification models; actually measuring and acquiring basic size parameters of a to-be-measured house platform and relative positions of the house and the power transmission line; performing model segmentation on a to-be-tested house platform to form a house platform simplified model taking the platform as a core; and according to the constructed house platform simplified model, calling a matched calculation method from the calculation method library to calculate the synthetic electric field at the house platform to be measured. According to the method, the synthetic electric field around the house
