Wind power operation maintaining system and maintaining method

Abstract

The invention discloses a wind power operation maintaining system and maintaining method. The system herein includes a monitoring wind turbine generator off-course brake and maintaining system, a windfarm level maintaining system which is disposed in a wind farm central control room, a district level maintaining system which is disposed in a wind farm cluster control center and a sharing maintaining system. According to the invention, the maintaining method herein includes the following steps: data transmission, model-based state evaluation, state monitoring and maintaining and data storage.The method can analyze operation conditions, fault identification, and level-differentiated operation recording and maintaining. The system and the method can serve as effective communication bridgesamong wind power equipment manufacturers, wind power operators and wind power equipment fault diagnosis experts, can help wind power equipment manufacturers to improve the production quality of equipments, and provide an effective technology support platform for efficiently operating and maintaining wind farm equipments.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a wind power operation and maintenance system and a maintenance method. 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. 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 wi...

Areas rich in wind energy resources are generally relatively remote and have harsh environments. In wind power stations, the distribution of wind turbines is relatively dissipated 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 money, and a large number of unused spare parts will be due to expiration. , rust or corrosion instead of normal wear and tear, and the utilization rate is low; and due to the large variety of spare parts, some spare parts will affect the operation of the wind turbine due to the long procurement cycle, and at the same time cannot realize the operation status analysis, fault identification, and graded operation records and maintenance operations
