Research On The Wind Turbine End-of-Warranty Acceptance Procedure Optimization

Wind power development in China started late, speed, overall level of growth is far more than the world in recent years.Wind power industry rapid development has attracted a large number of investment, the market competition ability and capacity increased significantly.After great development in new energy, new energy wind power companies are currently facing mass wind turbine(hereinafter referred to as the fan) out of the warranty period.The fan who after a large number of the quality assurance for missile d etection maintenance, on-site maintenance personnel, combined with the technical force is weak, the inadequate for maintenance tasks.In order to control the quality assurance period after the end of the risk of the fan before the warranty need to find professionals to conduct a comprehensive inspection of the fan, check the objects including rotor, yaw system, electric control system, transmission chain and the tower drum and interior parts, etc.This greatly reduces the probability of the fan problems after the warranty, but the late maintenance or a challenge for wind power company.The fan manufacturer of wind turbine and wind power company is a guarantee of acceptance of the content, inspection methods, evaluation indexes such as often cannot agree, to a certain extent, affected the progress of the project, so to write this article for wind turbines, summarizes the elements of inspection and acceptance in the sales contract, put forward the standard of the acceptance of wind turbines, provides a theoretical basis for the machine manufacturer and wind power company, so as to greatly promote the wind turbines is a guarantee of acceptance of the schedule.This paper takes datang, wind power generation co., LTD.(hereinafter referred to as Xi Meng company) Ming Yang 1.5 MW wind turbine as an example, in order to solve the fan out is a guarantee of acceptance of the low efficiency, big cost of acceptance, acceptance of the required materials to the arrival of the goods on time, the optimization of ideas and specific optimization measures are put forward.Xi Meng company big west hill farm Ming Yang 1.5 MW wind turbine is a guarantee of acceptance work began before Ming Yang fan for sampling and sampling inspection report, the defects found in order to Ming Yang company.Carried out in accordance with the sampling report questions item by item, rectification, reach the standard of fan again after pre-acceptance, acceptance, final acceptance of the work.Out of the wind turbine is a guarantee of acceptance of the existing in the process, find the problems existing in the existing processes, and from two aspects of consciousness level and behavior level analysis of the fan out of the warranty period of the acceptance process problems and causes.For wind power company, not just worry about the problem of fan out is a guarantee of acceptance, and fan out of warranty period after the site maintenance staff whether can smoothly receive fan, so before out of warranty in cultivating a batch of high level of maintenance personnel, and with the factory set up in the late tech support problem, these need to be in the warranty period in the process of acceptance of contract, on the one hand, from the power company’s trouble back at home, on the other hand fan manufacturer late technical support is also a kind of welfare, can be paid to help with some "incurable diseases", large parts replacement, etc., this way of win-win will promote the overall progress of the acceptance process.Fan manufacturer in wind power company pay the quality retention money, these quality retention money to take up the big fan manufacturer’s liquidity, its influence is serious and far-reaching, even though it looks like a fan between manufacturer and wind power company, but it can affect the entire wind power industry chain, thus, how to properly solve the quality problem, is suspends in front of the wind industry priority.Developers with the whole business of third party agencies through mutual recognition, USES the unified specification to evaluate the quality assurance program, to use the quality assurance to get an objective and fair and efficient solution.In the long run, the fan manufacturer to deal with quality problems give enough attention, to ensure the quality of equipment and related service level enhances unceasingly.Through experience accumulated and the idea of progress, the improvement of the relevant technical specifications and indicators will be, to solve the quality problem of long-term mechanism will be gradually formed.
