Platform for analyzing heavy electric equipment health and analysis method using same

Abstract

A platform for analyzing the soundness of heavy electric equipment comprises: work site diagnosis information input of receiving an input of data collected from the work site while a motor is stopped; online sensor data collection of periodically / discontinuously collecting data of installed sensors through a sensor module and a data collecting module; database construction using a work site diagnosis information input step and an online sensor data collection step; current reference soundness analysis of including direct current test analysis, alternating current test analysis, dissipation factor test analysis, and partial discharge test analysis, and diagnosing the soundness of the heavy electric equipment according to the current reference on the basis of data input in the work site diagnosis information input step; trend-based soundness analysis of linking to a database constructed in a database construction step to estimate an expected annual trend to analyze soundness; degradation prediction simulation analysis of generating a simulation model to analyze the soundness of the motor; online sensor data analysis of using online sensor data collected in the online sensor data collection to analyze the soundness of the heavy electric equipment; and automatic diagnosis result determination.

Description

technical field [0001] The invention relates to a soundness analysis platform of a heavy motor and an analysis method using the same. Background technique [0002] Old heavy electrical machines such as generators, transformers, electric motors increase the probability of failure and insulation breakdown. Especially in the case of electric motors, motors that have been in operation for more than 10 years are responsible for most insulation breakdown failures. Many operating power plants and large factories have been built for more than 10 years, so heavy-duty motors have begun to age. [0003] Heavy-duty motors are important equipment for operating power generation equipment. If a failure occurs, it will cause serious problems such as stoppage of power generation. If insulation damage occurs, in addition to repair costs, loss of profits due to power failure will also occur, and there will be losses Examples of surrounding equipment. [0004] Current standard analysis metho...

AI Technical Summary

Problems solved by technology

However, not only are the characteristics of heavy-duty motors of each manufacturer different, but also the characteristics of heavy-duty motors of the same manufacturer are different according to the time of manufacture, so that based on these characteristics, it is difficult to predict failure by the current absolute standard analysis method

Moreover, the current standard analysis method or system evaluated in the field stores data separately without history management, so there is also a lot of inconvenience in managing soundness history data

[0005] In addition, plant companies, test companies, test equipment companies, and test experts, who are stakeholders in the soundness analysis of heavy-duty motors, contact and work individually, so it is extremely inconvenient to conduct business
