The invention provides an electric locomotive electric transmission control method for improving network voltage and an electric locomotive. The control method comprises the following steps: S1, acquiring a unit length impedance value of a power grid and real-time operation parameters of the electric locomotive; s2, calculating a reactive power compensation value of the power grid in real time according to the unit length impedance value of the power grid and the real-time operation parameters of the electric locomotive; and S3, inputting the reactive power compensation value of the power grid to a four-quadrant rectifier of the electric locomotive, and performing reactive power compensation on the power grid in real time by adjusting a control strategy of the four-quadrant rectifier of the electric locomotive. Real-time reactive compensation of the power grid is achieved by combining the power grid impedance value and the real-time operation parameters of the electric locomotive, and the stability and the energy utilization rate of a power system are improved; extra equipment is not needed, and the cost and complexity of the reactive compensation system of the power grid are reduced; through real-time monitoring and cooperative control, required reactive compensation can be accurately provided for a power system.
