Method and system for simulating uplink pilot initiation and development process of line

The invention discloses a method and system for simulating the uplink pilot starting and developing process of a line, and belongs to the technical field of lightning protection of power transmission and transformation projects. The method comprises the following steps: determining a line uplink pilot starting condition of a direct current transmission line under the action of corona space charges; determining a line uplink leading development model of the direct current transmission line under the action of the corona space charge; and according to the line uplink pilot starting condition and the line uplink pilot development model, simulating the uplink pilot starting and development process of the direct current transmission line under the action of the corona space charge. According to the method, the leading starting and developing process of the line under the corona space charge condition can be calculated, and the influence mechanism of the corona space charge on the direct-current line tangent tower
