Problems solved by technology

The two detection methods overlap in principle. The ultraviolet imaging detection is easily affected by the distance factor. The instrument internally performs gain processing on the ultraviolet photons entering the optical system. The influence of air pressure, temperature and humidity is also very serious. In practical applications, humidity The increase of corona will cause the increase of corona intensity, but due to the uncertainty of pollution components and humidity, there is no way to correct its influence at present, so it will affect the judgment of the nature, location and severity of the internal fault of the equipment

Abstract

The invention provides the state test method of wind power plant equipment live detection. The method comprises the following steps of (1) carrying out live detection: using an apparatus to collect data, implementing the live detection combining ultrasonic partial discharge detection and ultraviolet imaging detection, monitoring the operation state of wind power plant equipment, and carrying out fault detection and prevention; (2) constructing decision system state overhauling: collecting and analyzing the operation data of the equipment, and carrying out state evaluation work on the equipmentso as to determine whether the equipment needs overhauling and determine overhauling items; (3) establishing an equipment pre-test overhauling optimization scheme: through wind power plant equipmentstate overhauling, combining the implementation of equipment live detection, according to a power plant equipment state evaluation rule, carrying out state evaluation on the equipment, and making a customized overhauling strategy. The invention also discloses a corresponding detection system. A live detection method combining the ultrasonic partial discharge detection and the ultraviolet imaging detection is adopted, a test project is optimized and pre-test overhauling cost is saved.

Description

technical field [0001] The invention belongs to the field of state evaluation and maintenance of electric equipment, and in particular relates to a state test method and system for live detection of wind farm equipment. Background technique [0002] The operating status of wind power generation equipment depends on the operating status of the overall structure of the wind power generating equipment. By monitoring and evaluating the operating status of wind farm equipment, hidden dangers can be discovered in time, the cause of the problem can be found out, and corresponding measures can be taken for the faulty parts of the equipment. Corresponding maintenance and repair measures provide the basis, which can not only save the maintenance and repair costs of wind power generation equipment, but more importantly, prevent the entire power generation process from stopping due to structural failures, and even bring danger to people's lives, as well as to enterprises. cause major ec...
