Reducing the enormous maintenance cost is essential to enhance the competitiveness for power plants. An overall design scheme
for condition-based maintenance of induced fans is proposed for large thermal power plants. The interface of the above framework
is simple and convenient; the optimum maintenance strategy is given by condition monitoring and risk evaluating. The decisionsupported
system was used in Guangdong Shajiao C Power Plant. The results show that it is a feasible maintenance optimization scheme
for power plants.

前 言
在可再生能源的家族中,资源量最大、分布最普遍的是太阳能,事实上,其它可再生能源也间接来自于太阳能。全球权威能源机构预测,到本世纪中期太阳能将成为人类能源构成中的重要组成部分,而到本世纪末太阳能将成为人类能源构成中的主要部分。我国陆地表面每年接受太阳辐射能相当于约49000亿tce(标准煤),全国三分之二的国土面积年日照在2200小时以上,年太阳辐射量超过5000焦/米^2(相当于170千克标准煤/米^2),太阳能资源丰富,是中华民族赖以生存,永续繁衍的最宝贵的资源。 相似文献

This research studies the low carbon transition of the electric power sector in China using a multi-level perspective (MLP) of niches, socio-technical regime, and landscape, as well as literature on innovation systems. Three lines of thought on transition process are integrated in the paper to probe the possible transition pathways in China. A MLP analysis is presented to understand the current niches, regime, and landscape of China’s power sector. A brief analysis on the future macroscopic socio-economic transition in the process of industrialization, urbanization, and modernization of Chinese society and its implication on power landscape are depicted to prove the urgency and magnitude of transition in China and why systematic transition management is needed. Five transition pathways, namely reproduction, transformation, substitution, reconfiguration, de-alignment/re-alignment, and reconfiguration, with their possible technology options are presented. The paper goes further to propose an interactive framework for managing the transition to a low carbon energy system in China. Representative technology options are appraised by employing innovation theory to indicate the logic of policymaking within the framework. Institutional gaps in realizing the transition are also addressed. The work presented in the paper will be useful in informing policy-makers and other stakeholders and may provide references for power sector transition management in other countries. 相似文献

The major subjects of this paper are to report the outline of the recent basic research and technical development for solar thermal electric power systems in Japan. Solar thermal electric power systems are presently being developed as one of the most important systems in Sunshine Projects which were initiated in 1974 to develop the utilization systems of new energy resources. Conceptional designs of solar thermal power systems were already done on the basis of the results of the supporting researches and two pilot plants of solar thermal electric power systems of a capacity of 1000 kWe are under construction on the basis of the conceptional and detailed designs and would be constructed by 1981. The present conditions of these pilot plants and the major researches which are thought to be most important subjects in the basic researches and technical developments for solar thermal electric power systems are described in this paper. 相似文献
