T. General Power Plant Study The Optimization Of Time Unit4Large Maintenance

Power plant generating units overhaul project is a huge amount of a project andthe complex relationship between the work of maintenance project, the relationshipbetween the structure of complex, completed the overhaul project investment ofmanpower, material resources, money and time need very much investment. Manypower generation enterprises have been using the most traditional managementmethods to overhaul the unit overhaul project, the reason is that it is convenient toapply.. Using traditional methods of enterprise does not take into account the need toinvest the resources and human behavior factors, causes the waste of time waste andoverhaul cost resources to overhaul project, realize the serious influence powerenterprises annual economic benefit target. Facing the power industry especiallyfierce competition among power enterprises, how to improve the level of projectmanagement in the overhaul project, under the precondition of ensuring themaintenance quality of maintenance work and effectively reduce cost, shorten themaintenance period, is a power generation enterprises to face the reality problem.On the outage management process in thermal power plants, according to A levelinspection standard for coal-fired power units, to formulate A plan. Solve T powerplant unit4unit equipment overhaul of several basic questions: what inspection,determine a goal, how to repair, statistics, project man-days and cost responsibilityimplement, how to carry out maintenance guarantee, how to evaluate repair effect.The system management method innovation characteristics embodied in scientificplanning, project management and overhaul management on standardization systemapplication. Overhaul of unified planning, including overhaul, overhaul organizationdecision-making, overhaul plan, overhaul process control, work implementation,safety requirements, quality management, evaluation index, overhaul, etc. The wholegenerator overhaul involving major breakout, electric boiler breakout breakout,pulverizing breakout, power generation, thermal breakout, turbine breakout breakoutmultiple breakout collaborate to complete. Engineering of the time limit for A projectfor A check to optimize overhaul goal will be more clear, can make the plan will bemore strict, work can be more effective. Through to understand T power plantbusiness conditions, production characteristics and the analysis of the actual situation.For the upcoming unit4large maintenance project, the progress of the preliminary plan, to the collapse of the inspection and repair, generating set to maintain, restore orimprove equipment performance, by judging equipment abnormal, predict theequipment fault, A start of A complete set of scheme after inspection, commissioning,maintenance after the interconnection preservation measures.Large maintenance period optimization analysis of the influential factors ofbuilding optimization model, the comparison and analysis, the result of theoptimization model and the maintenance process of experienced personnel,organization, technology, system, risk precontrol and so on a series of work, majoroverhaul period of4units to optimize the formulation corresponding guaranteemeasures. Do schedule optimization for large thermal power plant unit overhaulefficiency, economy and overhaul in the shortest possible time to complete the projectto provide a more reasonable management model.
