Embodiment Construction

[0020] The method of the present invention is based on the following common electrical equipment maintenance process: (1) the equipment operates normally; (2) the equipment enters the offline maintenance process due to reaching the maintenance period, or abnormal online monitoring parameter values, or other obvious abnormal conditions; (3) The equipment is offline, that is, offline detection is carried out without electricity, and whether the equipment is abnormal and the corresponding evaluation level is determined according to various parameters and corresponding guidelines; (4) According to the equipment conditions, carry out routine maintenance or repair; (5) During maintenance or repair After the end, the off-line detection is performed again; (6) the equipment is put into operation, and the process of (1) is repeated.

[0021] Specific steps are as follows:

[0022] 1. Start from the asynchronous parameter equivalence evaluation of the equipment, set the cycle informatio...

Abstract

The invention discloses a method for determining an online monitoring parameter evaluation level, which comprises: a step 1 of starting to evaluate a device, setting period information, and calculating the current number of running-maintaining-running times as the pth; a step 2 of monitoring and recording online parameters required to be evaluated during the live operation of the device; a step 3of set a corresponding offline parameter F; a step 4 of obtaining the online parameter typical value during the pth operation; a step 5 of obtaining the offline parameter typical values before and after maintenance; a step 6 of averaging the multi-device parameters for a re-commissioned power device; and a step 7 of establishing an evaluation level Sp_1 corresponding to an online monitoring amountOp, and an evaluation level Sp_2 corresponding to the online monitoring amount Op+1_new. The technical problem is solved that there is no method for evaluating the equivalence between online monitoring and offline detection parameters of the power device.

Description

technical field [0001] The invention belongs to the field of equipment life and reliability evaluation, and in particular relates to a method for determining the evaluation level of on-line monitoring parameters. Background technique [0002] Online monitoring, or live test, has been partially used in the management of various key power supply equipment by power companies. Compared with conventional power failure detection, online monitoring has many advantages. Since the equipment is not isolated from the power outage, the outage monitoring can effectively improve the availability factor of the equipment, reduce the outage rate, greatly reduce the over-repair and disrepair, and at the same time reduce the burden of operation and maintenance and the impact of the outage maintenance process on each link. [0003] Due to the limitations of detection methods, promotion time, and experience accumulation, online monitoring methods have not completely replaced traditional power ou...
