Calculation Model of Operation and Maintenance Costs of a Substation Project in Electricity Market Environment

With continuous economic development, the number and construction scale of substation projects in an actual power system are gradually increasing. At the same time, with the ever-developing power industry restructuring, power grid companies are facing more and more pressure on cost management. For a large-scale substation, the cost in operation and maintenance stage is large and includes many components. At present, most power grid companies roughly calculate this part of the cost, and it is difficult to meet the refined management requirements in the electricity market environment. This paper addresses the composition and charging rules of the operation and maintenance costs associated with a substation project, and presents the detailed calculation models of the cost, so as to facilitate the refined management of the substation project cost for a power grid company.
