When the train is running, if the catenary is heavily covered by ice, there will be arcs between the pantograph and the catenary, resulting in the train to be powered abnormally, even causing major accidents such as catenary breaks and pantograph damage. This paper proposes an ice-melting scheme based on energy cycle which is formed between the medium voltage grid and the icing catenary. The current of the catenary is controlled over the ice-melting current, which produces Joule heat to melt the ice. This paper analyzes the working principle and control strategy of the ice-melting system, calculates the ice-melting current, verifies the effectiveness of the control method and realizes the expected energy cycle by simulation.
