Research on Operation Risk Assessment Technology of Distribution Line Equipment Based on MARCOS Method and Equipment Running State

As the main part of the network, the stable operation and good maintenance of the distribution network equipment are the basis of realizing the reliable operation of the distribution network. In recent years, the number and types of distribution network equipment have increased rapidly, the network structure of the distribution network has become more complex, the operation mode is more changeable, and the risks of more and more problems are faced. How to accurately combine various factors to assess the risk of power distribution equipment, reasonably arrange the order of transformation and upgrading of risk equipment, and realize the safe and reliable operation of power distribution network has become a key problem for power grid enterprises to solve.
