Embodiment Construction

[0020] The method of the present invention is based on the following common power equipment maintenance process: (1) the equipment is in normal operation; (2) due to reaching the maintenance period, or the online monitoring parameter value is abnormal, or there are other obvious abnormalities, the equipment enters the offline maintenance process; (3) The equipment is offline, that is, offline detection is performed without power on, and whether there is any abnormality in the equipment and the corresponding evaluation level is determined according to various parameters and corresponding guidelines; (4) routine maintenance or repair is performed according to the equipment condition; (5) during maintenance or repair After the end, the offline 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. Starting from the equivalence evaluation of the asynchronous parameters of the eq...

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, in particular to a method for determining the evaluation level of online monitoring parameters. Background technique [0002] Online monitoring, or live testing, has been partially used in the management of various key power supply equipment by power companies. Compared with conventional power outage detection, online monitoring has more advantages. Since there is no power-off isolation for equipment, non-power-off monitoring can effectively improve the availability factor of equipment, reduce the outage rate, greatly reduce the situation of over-repair and disrepair, and reduce the burden of operation and maintenance and the impact of power-off maintenance process on all links. [0003] Limited by detection methods, promotion time, experience accumulation, etc., the online monitoring method has not completely replaced the traditional blackout detection method. In view of...
