Abstract:With the rapid growth of social demand for electricity, power grid operation is an important barrier to ensure the safe and stable operation of the power grid. In order to evaluate the operation status of the power grid, the main factors affecting the operation risk of the power grid are firstly identified, an evaluation index system including structure, equipment, management and environmental factors is constructed, the weight of each index is calculated by interval analytic hierarchy process, and then an operation risk evaluation model is established based on matter-element extension method. Finally, a specific example of a power transmission and transformation project in a certain area of Jiangsu province is analyzed, and corresponding countermeasures are put forward, which provides guarantee for the safe and effective operation of the power grid project in the future.
