Title:
METHOD FOR GENERATING VISUALIZED IMAGE OF DETERIORATION TENDENCY OF AC ROTARY MACHINE
Document Type and Number:
Japanese Patent JP2023066074
Kind Code:
A
Abstract:
To provide a method for generating a visualized image of deterioration tendency of AC rotary machines which is to centralizedly manage and visualize a deterioration tendency of a plurality of AC rotary machines, which can be used for planning a long-term maintenance plan, and which can secure a budget and personnel in advance, thereby to assist the maintenance to be efficiently carried out at an appropriate timing.SOLUTION: A method for generating a visualized image of deterioration tendency of AC rotary machines achieves centralized management of deterioration tendency of the plurality of AC rotary machines using a computer. The computer totals up the number of abnormal occurrences for each evaluation item of the AC rotary machines in which anomalies have occurred in data of maximum discharge charge Qmax and estimated breakdown voltages Ed, of all the AC rotary machines, for each elapsed year of the AC rotary machines from the start of usage to the evaluation time, to generate a distribution diagram of a total number of machines that shows a distribution of the numbers of all the AC rotary machines for each elapsed year, and a distribution diagram of abnormality occurrence that shows a distribution of the number of machines of abnormal occurrences by evaluation items for each elapsed year.SELECTED DRAWING: Figure 2
