Research on differentiated input of operation and maintenance cost based on different power grid equipment states

equipment states, equipment risk assessment, maintenance cost

As an important basic energy industry, the power industry provides basic operating power for other industries of the national economy, which is closely related to the development of the national economy. With the sustained and healthy growth of China's economy, the domestic power demand is also increasing steadily. This paper studies the differentiated input of operation and maintenance cost based on different equipment states establishes the equipment risk assessment model obtains the quantitative risk index by using the state assessment and fault probability statistics methods and makes decision-making and optimization of the maintenance plan to minimize the comprehensive cost in combination with the equipment maintenance cost model and fault risk cost model, Reduce the maintenance cost of the equipment and the failure risk that may be caused by unreasonable maintenance as much as possible, scientifically arrange the maintenance time and items, obtain the economic and technological comprehensive optimal condition-based maintenance scheme, and ensure the safe and reliable operation of the equipment.
