Promoting Quality Management Capability In A Large-scale Wind Turbine Manufacturing Enterprise

Since2006, with the implementation of Renewable Energy Law of the People’s Republic of China, wind power in China has achieved rapid development. As a link between the upstream parts enterprises and downstream wind farms, wind turbine equipment manufacturing enterprises have played an important role in the wind power industry chain. However, behind the rapid development, quality problems have become increasingly prominent, and even had occurred wind turbine tower collapse and fire, large parts scraped in batch and such serious quality problems. How to promote the quality management capability of wind turbine equipment manufacturing enterprise, is an important topic worthy of study.This thesis based on the study of the related quality management theory and methods, combined with the character of parent-subsidiary and large wind turbine manufacturing situation of quality management, based on the principle of from top management perspective and focus on the top-level design analysis and solve the problem. Research shows that, the main reason to cause quality problems is quality management mode, therefore put forward establish the procedures for interface control, improve three quality management functions and strengthen the project quality improvement. Through the study of the quality problems of the wind turbines, a few key parts caused to most faults, aiming at these problems, puts forward using the concept of quality grading for items and services, as for the design and development, supply chain management, assembly, installation commissioning and operation maintenance, these four value-added processes, using PDCA (Plan-Do-Check-Act) method for continuous process improvement to analyze and make scheme for promoting. Through comparison study on ISO9001:2008quality management system and the special requirements of wind turbine products, the enterprise shall supplementary requirements based on the ISO9001:2008standard and make it as the enterprise standard. In addition, using Potter’s five forces model, the necessity to implement the quality management were analyzed, and proposed that the enterprises shall implement quality-leading strategy, and the strategy implementation by using project management method for getting the effective strategy management had been proposed.This thesis combined quality management, project management, strategy management, stressed the importance of quality assurance, quality control and quality surveillance plays an important role in the project, this thesis has universal significance for the quality management capability promoting in the related enterprises of wind power industry chain, especially for the large-scale wind power machine manufacturing enterprises.
