Finally, in the final decommissioning phases, the specialists should focus on wind power generation system, and to consider the issue of technical, economic and environmental aspects. The practice must be considered in its technical advantages and economic benefits. The each turbine annual material cost estimate and Gearbox and the main bearing R & R Crane Erection are shown on Table 4 and Table 5 respectively. Turbine Size 1.5KMW Gear oil filter 200 Hydraulic filter 100 Offline filter 100 Gear oil 20 Yaw gear grease 279 Bearing grease 120 Oil testing 90 Electricity 1314 Table 4 The each turbine annual material cost Turbine Size 1.5 MW Tower Height 70 m Gearbox Weight 10 mt Crane Size 400 ton Crane Type Conventional crawler R&R cost $70,000 Table 5 Gearbox and the main bearing R & R Crane Erection In addition to other external factor, there are several measures to reduce the maintenance cost. 2.5.4 Develop a well-structured logistic plan A comprehensive logistics plan can make operation and maintenance personnel more effectively to deal with the problem occurred breakdown, minimizing downtime of the turbine. Then, a logistics plan will identify major fault events, and lists the maintenance task, which needs to implement. A well-prepared plan may fail and would be expected to prepare spare parts inventory, manpower and equipment. 2.5.5 Improve training Talents are paly vital role in completely proper maintenance and diagnosis the fault more effective. Most turbine manufacturers provide their own fully trained technical staff as well as the site owner. Usually, experienced wind field staff will work with the staff of the manufacturer during the warranty period. With the introduction of latest generation of wind turbines, the required maintenance technicians have increased in the range of skills. The mechanical and hydraulic systems remained relatively consistent, and diagnosis, control and power electronics systems have become increasingly complex. Operators must make relevant professional knowledge. If the wind farm is large enough, trade specialization may be an option. 2.5.6 Improve maintainability Maintainability refers to the relatively easy, and perform machine maintenance-related tasks, including routine maintenance and unplanned maintenance. Maintenance personnel are very good at finding effective ways to perform daily tasks. Their suggestions and comments should be in the process of continuous improvement. The ability of staff is to diagnose problems and select the appropriate corrective actions. Turbine manufacturers are well aware of this, generally including extensive troubleshooting chart to help employees analyze the problem. Most turbine control system includes some diagnostic information on the status of various subsystems. Some manufacturers currently focus on remote turbine & project monitoring. Professional knowledge and experience, which is contributed to the rapid narrowing of field experience and design of improved circulation. 2.5.7 High performance condition monitor Condition monitor is an important part of maintenance program. Comprehensive monitoring program can develop into failure or serious fault …show more content…
Comprehensive evaluation system requires the ability to reflect the impact of wind farms of various factors on the system, especially the human factors, the purpose of this paper is to analysis of a wind farm of 100 wind turbines, in order to complete the aim of the project, it is important that to establish a comprehensive evaluation system. Meanwhile, from the evaluation system can also be seen that the cost influenced by several dimensions, for instance, wind energy resources, wind turbine design and layout, wind farm construction and investment, operation and maintenance of wind farm operation. Then, I believe that with the development of science and technology, the wind farm construction and operation efficiency will be increasingly high in the
