Research On Quality Improvement Of AT Distributed Energy Station Project Maintenance Of A Company

Distributed energy station is a key industry supported by the state.How to make the energy station unit operate in the best condition,tap the potential of enterprise maintenance quality management,and improve the efficiency of energy station unit equipment is a common problem faced by China's distributed energy industry.Since the AT energy station was put into operation,the maintenance cost has remained high and continues to rise,which has caused great trouble to the company management.This paper firstly analyzes the development of domestic distributed energy stations and their problems,and collects and summarizes the relevant data of AT energy station's recent overhaul.It is found that the most prominent problem that leads to the high maintenance cost of AT energy station maintenance and repair costs is that the qualification rate of inspection and acceptance is low,and it is used as a subject for special research.In this paper,the data related to the maintenance quality of AT energy station in recent years has been combed in detail.The tools such as histogram,pie chart and line drawing have been used for analysis.It is found that the qualification rate of equipment inspection is only about 90% and shows a downward trend.The data from 2016 to 2017 indicates that the main overhaul problems of AT energy stations are the three aspects: equipment leakage,equipment vibration failure and equipment insulation failure,which account for more than 96% of all inspection failures.Then,using the fishbone diagram,investigation method,interview method and brainstorming tools,the paper analyzes and demonstrates the primary and secondary influencing factors of the three main problems.At the same time,an expert group was formed.Through the mathematical statistics theory and the expert investigation method,the above-mentioned end factors were quantitatively analyzed,and the key factors were determined through calculation.The results show that the key factors affecting the low acceptance rate of AT energy station are “poor personal responsibility”,“unqualified quality of spare parts” and “low level of maintenance technology”,etc.In view of the above identified key factors,this paper uses the relevant theoretical knowledge of organizational behavior,human resource management and other related knowledge to develop the corresponding AT energy station equipment maintenance quality improvement program.Firstly,in the aspect of employee assessment,establish a standard working hour warehouse for maintenance projects and establish a differential reward system and a final elimination system;secondly,establish an inspection system to control the quality of quality inspection points(H point,W point)of important equipment of AT energy station.Then optimize the acceptance process,and add key quality point acceptance links on the original basis;Finally,strengthen the management of suppliers,establish a supplier blacklist system and a quality supplier recommendation system and make rational use of the company's ERP system for real-time,dynamic resource management.This paper then analyzes the feasibility of the above improvement scheme and puts forward the supporting safeguard measures.It also illustrates the effectiveness of the improvement measures through the comparison of the data before and after the countermeasure implementation,and provides reference for the maintenance quality management of the relevant energy stations.
