| Abstract: | Aiming at the engineering design of DC ice-melting device parameters in substations, the differences between calculation formulas of ice-melting current in different standards and specifications are compared and analyzed. Taking the parameter design of DC ice-melting device in a 500 kV substation for example, the calculation results of minimum ice-melting current, maximum ice-melting current, one-hour ice-melting current, DC ice-melting voltage drop, DC ice-melting device capacity and other parameters are given. Suggestions for the selection of parameter design formula of ice-melting device in practical engineering are proposed. |
