摘要：
To overcome the disadvantages of current operation and maintenance mode of integrated disconnecting circuit breakers, this paper proposes an operation and maintenance strategy based on risk assessment at three levels such as equipment, substation and grid. At the equipment level, the outage probability model for the integrated disconnecting circuit breakers is established by the health index theory, and the fault set is obtained. At the substation level, considering the connection form of the substation, a grid risk analysis model is formulated with the integrated disconnecting circuit breakers. At the grid level, the risks of all integrated disconnecting circuit breakers are assessed, and the risk tracking method is applied to determine the operation and maintenance order of each substation. According to the system risk of the whole operation and maintenance period, and combined the operation and maintenance costs, the operation and maintenance method of the integrated disconnecting circuit breakers is proposed to optimize the maintenance time and order of the integrated disconnecting circuit breakers in each substation. The analysis of example illustrates that, compared with current regular maintenance and condition-based maintenance, the proposed method satisfies maintenance requirements, and reduces the grid risk by 19.67% and 13.21%. The method achieves the refined operation and maintenance of the integrated disconnecting circuit breakers, and obtains better maintenance benefits. © 2020, High Voltage Engineering Editorial Department of CEPRI.
