Optimization of impacts parameters on the equipment of electrical networks during operation according to the technical condition

Abstract

Scheduled operation of power grid facilities is regulated by the relevant regulations based on a system of scheduled preventive maintenance. Maintenance and repair (M&R) of power grid facilities due to their technical condition increases demands for planning methods and models. In these conditions, the goals of the M&R management are aimed at improving the efficiency of the operation of electrical networks. They differ depending on the purpose and form of ownership of the latter. The article suggests a combined approach to planning maintenance of electrical networks using strategy depending on their technical condition based on optimization of impact parameters such as frequency and labor intensity under specified constraints and variability of management goals. To implement the proposed planning procedure, the authors developed and verified models of process maps. Each of them represents a local database including the information about the composition and complexity of operations, depending on the type of equipment and the type of corrective actions. In addition, a set of operational algorithms, that solve the issues of process automation in the maintenance system of electrical network equipment, has been developed. The analysis and discussion of the developed models and algorithms are carried out on a specific example illustrating the possibilities of improving the efficiency of equipment operation in the electrical networks on the oil fields.
