The Research And Application Of Lean Production In Substation Maintenance

In the period of 13 th five-year plan,the assets of the state grid corporation has greatly ascended,the number and size of the equipment in power company has increased in doubles,the pressure of better services and high efficiency has become much heavier,and the original management mode of power company will not be quite ready for the developing requirements.Human resources cost in the company is increasing,the number of staff is limited by the human cost and other factors,the growth rate is very small.The contradiction between the staff and the heavy workload in the substation maintenance department in power company is more and more prominent,the original production management cannot adapt to the goal for a modern power company.Lean management system can improve business performance and customer satisfaction,and can enhance the reliability of substation maintenance work efficiency and operation of the substation equipment,improve substation maintenance staff performance,team management,equipment reliability etc.Based on the background above,this article studied the lean management model in power grid enterprise substation maintenance.It first studied the current situation of the lean management in power grid enterprise substation maintenance by comparative analysis of the data,acquainted the lean management development at present,and then studies the relevant theories and methods of management.After studying the theory and practical experience,it also emphatically analyzed the five aspects in the substation maintenance of power company Y,including department production,safety control,quality control,evaluation performance and information management,it takes lean thinking to analyze current situation,and illustrates the necessity for continuous reform.Based on the value flow analysis of substation maintenance and the improvement of the process,the Lean Maintenance Management System for substation maintenance is established.According to the principle,method and means of elaborating management.It considers the problem and gives reform suggestion of production mode in substation maintenance,then expounds the concrete steps of improvement.Substation maintenance in power company Y constantly optimize overhaul process,actively promotes the reform of the internal organization,set up large mixed work team,adjusts the way of production and organization,make the maintenance management mode changed,and achieve the goal that the enterprise interior,professional post can complementary advantages,resource sharing and management smoothly,efficiency is improved.The research on lean management mode for the maintenance department and adjustment of organization mode in production,it includes staff stability,corporate culture,benchmarking,safety management and maintenance of quality management,Finally,It illustrates the feasibility and advantage of the lean management by the results after improvement,so as to provide the practice experience of lean management for the substationmaintenance in the other power company.
