【摘要】：中国经济已步入全球化竞争时代,电力作为一种基础性的商品,其价格不仅决定每个老百姓的生活成本,同时也决定着各行各业的生产成本及电厂职工的收入,决定着中国企业的全球竞争力。我国电力市场的厂网分家改革目标已实现,下一步改革目标必将是：市场化运作的竞价上网,能耗低、污染物排放少、经营水平好的企业将获得长足发展；相反的企业可能面临生存危机。而数字化电厂的出现就能很好的解决以上问题。本文通过对(1)数字化电厂的电气控制系统；(2)数字化电厂的机、炉及其它控制系统；(3)火电厂的性能分析、优化及仿真系统；(4)三维设计系统在数字化电厂应用；(5)神华万州数字化电厂应用实例；通过以上5部分研究分析提出：用DCS系统实现全厂主辅一体化控制；利用SIS系统的分析优化功能,不断降低电厂能耗水平；利用三维数字化设计技术实现电厂设备的全寿命周期管理,以利于电厂降低造价、缩短建设周期；利用ERP、MIS等系统及其它办公、财务、采购等软件,不断降低成本。所以说：数字化电厂能切实提高电厂的竞争力,能提前预防重大设备损坏及不必要的非计划停机,通过不断优化会给电厂带来良好的经济效益。数字化电厂能够提高电厂自动化水平、减少人员使用、降低能耗、降低污染物排放水平、实现提高经济效益的目标。最终实现：企业运营成本最优、能耗水平最低、污染物排放最低、人均产值最高的追求。
[Abstract]:China's economy has entered the era of global competition. As a basic commodity, the price of electricity not only determines the cost of living for every citizen, but also determines the production cost of various industries and the income of power plant workers. Determine the global competitiveness of Chinese enterprises. The reform goal of power market separation in China has been realized. The next reform goal will be: the enterprises with low energy consumption, low pollutant emission and good management level will get great development; On the contrary, businesses may face a survival crisis. The emergence of digital power plants can solve the above problems. In this paper, the performance of power plant is analyzed by means of the electrical control system of No. 1) the electric control system of the digital power plant, the machine, furnace and other control systems of the digital power plant, and the performance of the thermal power plant. The application of the three dimensional design system in the digital power plant is 5) the application example of Shenghua Wanzhou digital power plant, through the research and analysis of the above five parts, the author puts forward the following points: using DCS system to realize the integrated control of the main and auxiliary parts of the whole plant; The analysis and optimization function of SIS system is used to continuously reduce the level of energy consumption of power plant, the whole life cycle management of power plant equipment is realized by using 3D digital design technology, which is beneficial to reduce the cost of power plant and shorten the construction period. Make use of ERP MIS and other software such as office, finance, purchasing, etc., continuously reduce cost. Therefore, digital power plant can effectively improve the competitiveness of power plant, can prevent major equipment damage and unnecessary unplanned shutdown ahead of time, and will bring good economic benefits to power plant through continuous optimization. Digital power plants can improve the automation level of power plants, reduce the use of personnel, reduce energy consumption, reduce the level of pollutant emissions, and achieve the goal of improving economic efficiency. Final realization: the pursuit of optimal operating cost, the lowest energy consumption, the lowest pollutant emission and the highest per capita output value.
