Problems solved by technology

[0003] Areas rich in wind energy resources are generally remote and have harsh environments. In wind power stations, the distribution of wind turbines is relatively dissipative and there are many monitoring parameters, which will adversely affect the operation and maintenance of wind power systems
At present, most wind farm owners use self-monitoring for a single wind farm and independently build spare parts warehouses for maintenance. However, it is still difficult to achieve early warning and reasonable inventory despite a large amount of mon

Example Embodiment

[0034] see figure 1, the wind turbine condition monitoring device is mainly composed of various sensors installed in each wind turbine and the industrial computer. The frame collects the following raw signals: temperature of all bearings; engine room temperature, gearbox oil temperature, generator coil and air gap temperature; main shaft speed and generator speed; main shaft bearings, gearbox front and rear end bearings, and generator front and rear end bearings vertical vibration; vertical vibration of gearbox housing, base, yaw mechanism, nacelle and tower. The industrial computer is installed with wind turbine status detection system software, which is mainly responsible for controlling each sensor to complete the original signal sampling of the main components of the wind turbine, and transmitting the signals obtained by various sensors to the wind farm server after data conversion and preliminary processing. The server uses scanning to receive the data sent by the indust...

Abstract

The invention relates to the field of wind power generation, and provides a sharing maintenance system ensuring normal operation of wind turbines and a realization method thereof. The sharing maintenance system can rapidly diagnose the failure state of the wind turbines and effectively solve the problems of difficult building of the spare parts store of each wind power plant and difficult technical training for maintenance personnel. The sharing maintenance system is characterized in that the system comprises a wind turbine state monitoring device and a central data server, wherein the central data server is mainly composed of a wind turbine state analyzing unit, a user management unit, an inventory management unit, a transaction management unit, a technical training unit and a comprehensive analysis inquiring unit. The central data server is provided with a client-side interactive interface, and a user can use the client-side interactive interface to operate on a client-side computer through a network. By adopting the system, the sharing and the regulation of spare part inventory among different wind power plants can be realized. The system provides a professional assurance for wind power plant hosts to rapidly diagnose the failure state of the system and produces a great promotion role for increasing the operation reliability, safety and economic benefit of the wind power plants.

Description

technical field [0001] The invention relates to the field of wind power generation. Background technique [0002] The cumulative installed capacity of wind power generators in China exceeded 42 million kilowatts by the end of 2010, ranking first in the world. Wind turbines, referred to as wind turbines, are the key equipment of wind farms, and their operating status greatly affects the income of wind farms. It is very important to accurately monitor the operating status of wind turbines, especially the status of key components, and formulate effective maintenance plans to ensure the normal operation of wind turbines. [0003] Areas rich in wind energy resources are generally remote and have harsh environments. In wind power stations, the distribution of wind turbines is relatively dissipative and there are many monitoring parameters, which will adversely affect the operation and maintenance of wind power systems. At present, most wind farm owners use self-monitoring for a ...
