Research On Lean Management Of Thermal Engineering Maintenance In D Power Plant

The reform of Chinese power system clearly points out that it is necessary to restore the attributes of electric power products and orderly liberalize the competitive business.Accompanied by the all-round competition among power generation companies,the pressure on power generation enterprises is increasing day by day,including production services and internal aspects of work efficiency improvement,etc.The development background of modern enterprises has put forward new requirements for power generation enterprises.In fact,the development of power generation enterprises is still limited by the existing management mode.The growth of enterprise personnel is largely restricted by the increase of human labor costs.It is difficult to achieve a large increase.Modern power generation enterprises have put forward new requirements for production management methods,and the imbalance between personnel and workload of power generation enterprise maintenance departments has hindered the satisfaction of such demands.The construction of lean management system in enterprises has been an important role in promoting the development of all aspects of the enterprise,including the improvement of enterprise management level,the increase of operational efficiency,the improvement of maintenance work efficiency,the improvement of equipment operation reliability,the strengthening and overhaul of team management,performance improvement,etc.Based on the above research background,this paper takes the thermal maintenance department of D power plant as an example.From the perspective of lean management,the data and information of each process are collected,and the production overhaul process is analyzed in depth.It is found that the employees of thermal maintenance department in D power plant have low enthusiasm,poor maintenance process control and high maintenance cost.According to the current situation of thermal maintenance,the value flow chart is drawn,and the value flow analysis method is used to analyze and study the thermal maintenance in detail.By calculating the value-added time,non-value-added time and value-added time ratio of thermal maintenance process,it is found that the value-added time ratio of thermal maintenance is relatively low.Through the analysis of the existing problems,it is found that unreasonable team settings,poor control of overhaul process and inadequate incentive effect of personnel are the factors leading to more non-value-added time.Combining with the existing problems,the direction of improvement is clear,the goal of improvement is determined,and the lean management scheme is formulated in five aspects: production organization,maintenance quality,safety production,performance evaluation and production information system.Finally,the D power plant can improve production efficiency,reduce production costs,and reduce waste of lean management.
