Abstract

The invention discloses a method for maintaining the state of power transmission equipment based on a system risk. The method comprises the following steps that: a control system calculates the forced stoppage rate of the power transmission equipment to be maintained under the current state; the control system calculates a risk increment which is brought to the system by the power transmission equipment to be maintained under the current state; the control system sequences the importance of the power transmission equipment to be maintained; the control system screens feasible maintenance timeintervals of the kth power transmission equipment to be maintained according to restraint conditions; the control system determines the optimum maintenance time interval of the kth power transmissionequipment to be maintained; the control system updates the forced stoppage rate and operating data of the kth power transmission equipment to be maintained after maintenance, wherein k is equal to k+1; and if maintenance schedules of all pieces of power transmission equipment to be maintained are made, the system ends operation, otherwise, the system repeatedly executes the operation. By the method, a new equipment importance evaluation index is provided and can reflect the current state of the equipment and influence size of the system risk. On the premise of an operating mode of a power system and the time sequence change of the state of the equipment, the total risk of the system in investigation time is minimized.

Description

technical field

[0001] The invention relates to a power transmission equipment maintenance method, in particular to a system risk-based power transmission equipment condition maintenance method. Background technique

[0002] With the development of society and economy, the demand for electricity has grown rapidly, and the scale of the power grid has expanded rapidly. The society has higher and higher requirements for the reliability of power grid power supply. Equipment maintenance is an important measure to ensure the reliability of power grid operation, and the rationality of its maintenance strategy is crucial to the safe and economical operation of the power system. According to whether to consider equipment status and equipment importance, maintenance strategies are divided into post-event maintenance, planned maintenance, condition-based maintenance and reliability-centered maintenance.

[0003] After-event maintenance is to repair the equipment after it breaks down. ...
