基于相对劣化度模型的大型汽轮机状态综合评价 总被引:5,自引:0,他引:5
大型汽轮机设备工作状态性能的好坏直接影响到电厂运行的安全性和经济性,对其进行状态监测及状态综合评价很有必要。为克服传统状态评价方法的缺陷和不足,引入相对劣化度概念,充分利用设备运行参数、状态监测参数和运行统计参数,融合汽轮机本体振动信号、轴系运行参数以及通流部分热效率等多类信息,建立了应用相对劣化度的评价模型,开发了汽轮机本体状态综合评价系统并将其成功应用于国产300MW汽轮机本体状态综合评价中。研究结果表明,该方法合理有效,评价结果可为以后的本体维修决策提供科学依据。图2表1参6 相似文献

The hydrogen-based clean energy infrastructure provides a viable option for resilience improvement against extreme events, e.g., natural disaster and malicious attacks. This paper presents a resilience-oriented operation model for industrial parks energized by integrated hydrogen-electricity-heat microgrids, which aims to improve the load survivability under contingency status. The synergies of multi-type distributed energy resources (e.g., fuel cells, hydrogen storage tanks, battery storage and heat storage unit) and the sequential operation of the industrial distribution network are analytically represented by a mixed-integer second-order conic program (SOCP) formulation. Moreover, by leveraging the information of probabilistic disaster prediction, a risk-averse receding horizon method is developed to handle the uncertainty of network contingencies, and supports the optimal decision of proactive and emergency scheduling. Numerical results on a 26-node industrial energy system demonstrate the effectiveness of the proposed model and resilient scheduling method. The synergetic operation of hydrogen-based microgrids could significantly reduce the risks of load interruption. 相似文献

Environmental concerns and the increase in oil prices in the fall of 2000 made energy one of the priority issues in the industrial world. Research shows that the problem of selecting an energy resource requires a detailed multi-dimensional analysis. Most forms of renewable energy are dependent on geographic and environmental factors that vary immensely from place to place. As a result, each country has to work out its own policies in accordance with its geographical and political conditions. This paper is concerned with the multi-attribute decision making evaluation of energy resources that will enable the selection of a suitable electricity generation alternative for Turkey. It also provides an integrated decision aid (IDEA) framework for the selection of the most suitable multi-attribute method and presents ranking of alternatives and robustness analysis as recommendation to the authorities. 相似文献

This paper define the concept of the nuclear power integrated system as a fast-thermal one. the integration with three successive fast reactor generations is considered: first reactor genertion—LMFBR(PuO2); second reactor generation-LMFBR(CPu); and third reacator generation—GCFBR(PuO2). A time interval of [0, 40] years is considered and the time evolution of the integrated system is followed under the following circumstances: a time delay of 15 years in the case of the first reactor generation, 20 years in the case of the second reactor generation and 25 years in the case of the third reactor generation. By applying the mathematical model of integrated systems an analysis of the three nuclear power integrated systems is made and many important conclusions of interest to decision makers are also drawn. 相似文献

As the amount and complexity of information relating to the development of bioenergy systems increases so does the problem of how to handle the information in a manner which is helpful for decision making. Hypertext-based information systems and decision support systems are being developed to aid deployment of bioenergy systems.These approaches are discussed with reference to a short rotation forestry production information system and decision support systems for harvesting wood for energy from conventional forestry and short rotation forestry. The development of a model which integrates biomass production, conversion and electricity generation is discussed. Problems encountered when combining different models into an integrated model are addressed. 相似文献
