【摘要】：目前国内的火力发电厂度电燃料成本管理软件主要注重于学术上的研究以及独立系统的开发，，实际应用水平并不高，应用也不全面，软件集成度不高；国外软件应用比较早，实际也有大量的应用实例，但和国内的国情不是十分吻合，在国内也没有得到很好的应用。综合目前九江电厂现状和对国内外产品的研究分析，希望通过管理系统的研究和开发，解决九江电厂现阶段燃料管理、成本管理中的问题。在试验掺配数据库的基础上，全面收集各方面信息，设置相应边界条件，建立动态掺配计算模型。建立数字化煤场，实时掌握煤场整体情况；并根据掺配计划方案，指导煤场进一步分区、分段管理，参照发热量高低将煤种进行有规律堆放，降低存储及转运成本。建立完善的成本核算体系，并和燃料管理集成，根据掺烧数据、煤量、上网电量等完成全面的发电成本核算，并对计算出的机组经济指标以及变动成本进行实时分析，实现发电成本到燃料成本，从燃料成本到掺配方案、实际煤耗的跟踪分析体系，完善成本优化机制，实现燃料成本的持续优化。建立完整的燃料全生命周期管理体系，通过系统的开发，和现有燃料管理的集成，提高燃料管理的精细化程度，提高电厂管理水平。
[Abstract]:At present, domestic thermal power plant fuel cost management software mainly focuses on the academic research and the development of independent system, the practical application level is not high, the application is not comprehensive, the software integration is not high; The application of foreign software is early, and there are a large number of practical applications, but it is not very consistent with the national conditions in China, nor has it been well applied in China. Based on the current situation of Jiujiang Power Plant and the research and analysis of domestic and foreign products, this paper hopes to solve the problems of fuel management and cost management in Jiujiang Power Plant through the research and development of management system. On the basis of the experimental mixing database, the information of all aspects is collected, the corresponding boundary conditions are set up, and the dynamic mixing calculation model is established. The digital coal yard is established, the whole situation of the coal yard is grasped in real time, and according to the plan of mixing and distributing, the further partition and management of the coal yard are directed, and the regular stacking of the coal is carried out according to the calorific value, so as to reduce the cost of storage and transportation. Establish a perfect cost accounting system, integrate with fuel management, complete the comprehensive generation cost accounting according to the mixed burning data, coal quantity, power supply, etc., and carry on the real-time analysis to the economic index and the variable cost of the calculated unit. Power generation cost to fuel cost, from fuel cost to blending scheme, tracking and analyzing system of actual coal consumption, perfecting cost optimization mechanism, realizing continuous optimization of fuel cost. A complete fuel life-cycle management system is established to improve the degree of refinement of fuel management and the management level of power plants through the development of the system and the integration of the existing fuel management.
