Intelligent detection system and method for state of power grid unit

Abstract

The invention relates to the technical field of power monitoring, and provides an intelligent detection system and method for the state of a power grid unit. The system comprises a sensor unit, a dataacquisition and analysis module, a field server and a remote diagnosis center, wherein the sensor unit is used for monitoring unit operation parameters; monitoring signals are uploaded to the data acquisition and analysis module through relatively independent signal channels; the data acquisition and analysis module is used for processing and analyzing unit operation parameters and uploading theunit operation parameters to the remote diagnosis center through the field server; and the remote diagnosis center is used for analyzing and judging abnormal detection points. According to the intelligent detection system with the remote diagnosis center as the core, important operation parameters of all parts are obtained through a sensor unit composed of multiple sensors, and a signal algorithmlibrary and a fault judgment case library are matched to serve as supports for fault diagnosis to monitor, recognize and judge potential faults of main components of a unit.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to an intelligent detection system for the state of a power grid unit, and also to a detection method. Background technique [0002] Limited by geographical conditions and wind energy resources, wind farms are generally far away from cities and the headquarters of wind power companies, and the distance between wind farms of wind power companies may also be very far away, and the units are located on the top of the tower, which causes difficulties in maintenance ( Such as the entry of personnel and equipment, etc.), the current maintenance of wind farms mostly adopts the method of planned maintenance and after-the-fact maintenance. This kind of maintenance is difficult to understand the operation status of the equipment in a comprehensive and timely manner, which often results in protracted maintenance work and heavy losses. [0003] How to effectively monitor and a...
