The Theory And Practice Of Cascade Hydroelectric Scrolling Development Of Huanghe Upstream

To expedite the exploitation of hydroelectric resources of Huanghe upstream meets the request of Western Development, and is significant to the strategically overall arrangement of realizing the optimization deployment of resource and transporting clean energy to the east But, for a long time, in the electric market, the supply-and-demand analysis and the science-oriented, reliable forecast of electric network load is absent. In the developing gradation, the support of theory about hydroelectric plants' developing gradation is absent. In the pattern of management and development, a theoretical system of developing, management is absent, such as the relation of the synthetically utilization of hydroelectric development and water resource and environment should be brought into the unified planning and managing system of the valley. All the problems mentioned above, restrict the cascade development of Huanghe River's hydroelectric. Under the premise of actuality of analysis of Huanghe River's hydroelectric development, the author brought forward a strategically aim based on the cascade development system, found key technical issues of the development at present and in the near future. Firstly, aiming the marketing of hydroelectricity, that is, under the situation of separated plant and network, and entering the market by the competition of price, the author analyzed the advantages of the development of hydroelectricity. Secondly the author made a medium-long-period forecast and evaluation of the electric load of the accepting-electricity area by gray-and-nerve network matrix. Finally the author studied the pattern of cascade hydroelectric development of Huanghe upstream, analyzed and retrospect China's hydroelectric development and management, integrated with Chinese and abroad advanced pattern of management, brought out the pattern of the cascade hydroelectric development of Huanghe upstream. Though the study of basic theory and solution of cascade development gradation, the author brought two projects of the gradation of cascade hydroelectric development of Huanghe upstream.
