Currently, the situations of power supply and demand in 2006 and the other four years of the 11th Five Year are undoubtedly of great concern both inside and outside the industry. Aiming at the discussions that the power supply would appear "knee point" and even "surplus," the Editorial Department of the China Power Enterprise Management held the Forum on the Situation of Power Supply and Demand in 2006, at which experts aired their own views on the matter of "knee point." The experts’ talks are shortened out and introduced as below.展开更多
To trade off high energy consumption for high GDP growth making both energy consumption and environment pollution of the developing China top in the world is an undisputed fact. The 11th Five-Year Plan has stipulated ...To trade off high energy consumption for high GDP growth making both energy consumption and environment pollution of the developing China top in the world is an undisputed fact. The 11th Five-Year Plan has stipulated 20% decrease of specific energy consumption in this period as a restrictive index, this has been gradually detailed and practiced into every link. To compile the thesis of "How to Realize the Target of Energy Consumption 20% Decreased in the 11th Five Year period," this Journal invited Mr. Fang Weizhong, the president of China Macro-Economic Association to contribute a paper entitled "The Severe Energy and Environment Situation in China," in which reasons of failed target of energy consumption in the 10th Five Year period and how to realize energy consumption index in the 11th Five Year period are precisely calculated and in-depth analyzed with detail and practical data.展开更多
To improve the operation reliability of power supply system in China, it is of great significance to know the status of condition-based maintenance (CBM) in the system and accumulate related experience in recent years...To improve the operation reliability of power supply system in China, it is of great significance to know the status of condition-based maintenance (CBM) in the system and accumulate related experience in recent years. This paper analyzes the current modes of detection and repair, maintenance periods, the operation status of on-line monitoring devices equipped and the existing problems of them. The results show that there exists an urgent need in intensifying the quality control and inspection of on-line monitoring products at present.展开更多

Therefore, it is necessary to research the present situation and restrictive factors in the comprehensive utilization of FGD gypsum.展开更多

The selection principles can be detailed as: 1) the limestone-gypsum process is preferred in the case that the mass fraction of sulphur content in power coal is more than 1% and the capacity of a unit is no less than 200 MW. 2) the matured low-cost technologies such as dry or semi-dry processes are applicable in the case that the mass fraction of sulphur content in power coal is less than 1% and the capacity of a unit is less than 200 MW. 3) the seashore power plants with less than 1% mass fraction of sulphur content in power coal can take the seawater process into consideration.展开更多
