Abstract:Ice and snow weather is one of the natural disasters that have the greatest impact on the stable operation of the power system, causing icing on transmission lines and endangering the safe operation of the power grid. This article revolves around the process of preparing a line melting ice plan, focusing on the key and difficult steps in the process, and researching intelligent technologies to assist decision-making, in order to improve the quality and effectiveness of the melting ice plan preparation for the power grid control center. The specific content is as follows: preprocess the actual power grid operation data and icing data, achieve multi-source data fusion, and analyze the blackout and icing melting lines based on deep priority algorithm; Using the method of weighted mean comprehensive evaluation, prioritize and combine the melting ice route based on multiple indicators; Based on the evaluation method of DC power flow branch interruption distribution factor, quickly verify the ice melting scheme; Based on multi machine multi Task parallelism parallel processing technology, the ice melting scheme is checked in detail to improve the efficiency of ice melting scheme arrangement of transmission lines and ensure the safe and stable operation of power grid in ice and snow weather.
