Research on Ice-melting Method for Distribution Network Lines without Power Interruption Based on Load Transfer Method

Whether the distribution network lines can operate normally is directly related to whether users can use electricity normally. In winter, the distribution network lines are prone to ice, which causes the distribution network lines to fail to operate normally. This paper studies a method of melting the distribution network lines without power outage based on load transfer method. Ice method. Taking 10 kV distribution network lines as the research object, the principles and characteristics of ice melting without power outage for transferred loads are analyzed, and typical distribution network lines are selected for theoretical calculation and simulation analysis. The main conclusions are as follows: The principle, system structure and application conditions of ice melting without power outage for transferred loads are clarified; Both simulation analysis and theoretical calculation of typical lines show that this ice melting method is feasible; However, its application conditions are harsh, which limits its application range, and it is necessary to ensure that the current in the icing area is within the ice-melting current range. This research can provide technical guidance for melting ice on 10 kV distribution network lines without power interruption.
