Wind power plant inspection system

Abstract

The invention discloses a wind farm inspection system, wherein the wind farm includes a plurality of units, the wind farm inspection system includes a control device, an inspection device and a maintenance device, and the inspection device communicates with the control device connection, for performing inspection on the inside of the unit to obtain internal inspection data, and performing inspection on the outside of each unit to obtain external inspection data, and combining the internal inspection data and the external inspection data The inspection data are respectively sent to the control device; the control device is used to generate an inspection signal after processing the internal inspection data and the external inspection data, and send the inspection signal to the inspection device; The inspection device is arranged on the inspection device and communicated with the control device, and is used for inspecting the inside and / or the outside of the unit according to the inspection signal. The wind farm inspection system provided by the invention solves the problem of failure to detect when a fault occurs inside the unit.

Description

technical field [0001] The invention relates to the technical field of wind power equipment detection, in particular to a wind farm inspection system. Background technique [0002] At present, due to the scattered units, complex terrain and high transportation costs of wind farms, especially offshore units, the maintenance cost of wind farms is high due to high hoisting costs and high parts costs. If the wind farm fails, the shutdown of the units will also reduce power generation Therefore, it is necessary to conduct regular inspections on wind farms to realize fault diagnosis and fault prediction, and adjust maintenance strategies in time according to the operating conditions, so that unexpected faults can be changed into planned maintenance, and parts hoisting and replacement can be changed into on-site maintenance. . [0003] If an online monitoring system is used for fault detection in wind farms, the cost of the monitoring system will be high due to the problem that ...

AI Technical Summary

Problems solved by technology

[0002] At present, due to the scattered units, complex terrain and high transportation costs of wind farms, especially offshore units, the maintenance cost of wind farms is high due to high hoisting costs and high parts costs. If the wind farm fails, the shutdown of the units will also reduce power generation Therefore, it is necessary to conduct regular inspections on wind farms to realize fault diagnosis and fault prediction, and adjust maintenance strategies in a timely manner according to the operating conditions, so that unexpected faults can be changed into planned maintenance, and parts hoisting and replacement can be changed into on-site maintenance.

[0003] If an online monitoring system is used for fault detection in wind farms, the cost of the monitoring system will be high due to the problem that there are many wind farm units and many monitoring points for the same unit

At the same time, wind farms have factors such as long distances between units, high towers that maintenance personnel need to climb, and offshore units that need to carry ships or helicopters, which lead to heavy personnel burden and high operation and maintenance costs.

[0004] However, if a conventional UAV inspection system is used, although the existing conventional UAV inspection system for wind farms can adapt to towering units and complex terrain, this UAV can only detect wind turbines. Superficial conditions, unable to detect problems occurring inside the unit
