Design method of overhead ground wire grounding system close to buried oil and gas pipeline

The invention provides a design method of an overhead ground wire grounding system close to a buried oil and gas pipeline, and belongs to the technical field of power transmission and transformation project design. Comprising the steps of establishing an electromagnetic induction simulation model; obtaining an electromagnetic induction safety limit value of an adjacent buried oil and gas pipeline under the single-phase earth fault of the power transmission line; simulating a single-phase earth fault along the overhead transmission line in the electromagnetic induction simulation model; the coating induced voltage and the coating withstand voltage close to the buried oil and gas pipeline are calculated in a simulation mode; obtaining the minimum number of direct grounding points of the overhead ground wire; calculating the operation loss of the overhead ground wire under different numbers of direct grounding points by taking the number of the minimum grounding points as the minimum value and the number of towe
