The invention provides a method for evaluating a power grid maintenance scheme. The method comprises the following steps: firstly, determining various indexes affecting the power grid maintenance scheme according to factors including a weather condition, a geographical condition, a power grid topology, business distribution and personnel allocation in a practical situation; extracting m important indexes from the indexes as key indexes by a principal component analysis method for carrying out an evaluation on the power grid maintenance scheme; building a decision tree model by the key indexes, and training the decision tree model; and carrying out the evaluation on a to-be-evaluated power grid maintenance scheme by the trained decision tree model. The method has the beneficial effects that firstly, an index system for evaluating the power grid maintenance scheme is built; secondly, main component analysis is carried out on the index system and the key indexes are extracted; and finally the decision tree model is built through the key indexes, and the power grid maintenance scheme is reasonably evaluated by the model. According to the method, the comparative frequency in evaluation can be reduced; the evaluation process is simplified; and building of a scheme knowledge base is facilitated.
Description
technical field [0001] The invention belongs to the technical field of computer control, and in particular relates to a method for evaluating a grid maintenance plan. Background technique [0002] The power grid is the physical network of the power system and the main part of the grid intelligence. Its security and reliability will directly affect the stability of power transmission. Since different geographical conditions, weather conditions, network topology and some other factors will have different effects on the operation of the power grid, it is necessary to regularly overhaul the power grid to reduce the impact of these factors on the operation of the power grid. Before overhauling the power grid, it is necessary to make sufficient preparations and formulate a complete maintenance plan to ensure that various services of the power grid will not be affected during the maintenance period. A good maintenance plan will ensure that the operation of the power grid is safer ...
