White Mountain Research Station of economic operation
Bit, and should actively water storage reservoir to restore normal operation. (1) control the water level and water level control. Control the water level has two implications: First, determine the design of reservoir operation characteristics of the reservoir water level. Such as the normal high water level, dead water level, flood control level, the annual frequency of fluctuating water levels and a variety of the highest flood water level and so on. The water level is the main basis for reservoir operation. Second is the actual scheduling operation, the water level on the basis of design features, and further refinement. According to runoff forecasting, scheduling experience to develop the different seasons of the mid-late March until the beginning of reservoir water level to be achieved. According to different periods of regulation and operation of reservoir water level as water level control means. Currently,mbt schuhe test, the water level control Hakusan station is: From the beginning of storage (April 1), the water level gradually increased from 400m to the end of May to the 405m, then down to July 1 of the 403m, then slowly rose to flood at the end (October 1) of the 413m; supply of water levels slowly drop to the water supply down to the end of 4001 \To complete an annual adjustment cycle. Since the operation since the White Mountain Reservoir, 1983 (empty) -1986 (full) a 1989 (air) to 1995 (full) -2003 (empty) -2005 years (full), two and a half years to complete the adjustment period. (2) water level control analysis. The current water level control, since the main consideration of the periodic law of hydrological phenomena. Considered less random law, there are the following three major problems: ① the wet period and abandoned water losses. Although the wet opening flood control capacity reserved for a great, but the flood comes, because to a large amount of water or failure to increase the generating capacity. Still cause or increase the disposable water loss. ② flood fills the low end of reservoir. Beginning of the wet season flood storage capacity reserved for a great, low in the runoff year, or scheduling unreasonable year, less flood storage reservoirs at the end, Horton was very low. ③ normal water, dry season low water level. Water period and dry seasons failed to reduce the generating capacity. Resulting in continued low reservoir water level, causing huge losses. Power loss: White Mountain Reservoir head lower 1m, water rate increase 0.03m / (kW-h). The calculated total loss of power nearly 10 years 1.6 billion kW ・ h. Power loss: White Mountain Reservoir head lower 1m, single output decreased O. 40,000 kW, the plant output decreased 20,000 kW. This loss is invisible and huge, unlike the gate opening as easily disposable water concern. Comprehensive utilization of losses: the reservoir water storage less, affecting the shipping, tourism, aquaculture, irrigation and other utilization efficiency. 3 Baishan Hydropower Reservoir Operation under the Economic Operation of the needs of the two flood (spring flood and summer flood) based on the re-divided into three (the wet period,UGG Boots Outlet, in normal water, dry season). 7 August as the wet period: 4 to 6 months and in September as the water level period: October to next March as the dry season. Economic operation are: normal water,doudoune moncler, dry season water level elevation; wet at the beginning level unchanged; take into account flood control, try to avoid or reduce disposable water loss. Level increase during the wet season to a more cautious: water level of not less than the end of fluctuating water level of 400m. From the water level control is the way to the economic operation scheduling philosophy and scheduling shift in consciousness. The dispatcher thought, always an issue to consider is this: It is engaged in economic operation, we must do everything possible to explore the potential to plug the loopholes. Economic operation carried out this work would be better. 'From the beginning of storage (April 1), the water level gradually increased from 400m to the spring flood period (May 21) and 409n1; then dropped to the wet at the beginning (July 1) of the 403m; then a slow rise to abundant water period (August 20) in 413m; wet period (September 1) to 416.5m; flood at the end (October 1) was maintained at 416.5m; water slow decline of water level, at the end (January 1 days) 408.5m; to supply end (April 1) down to 400m. Complete a run cycle. Economic operation, to avoid or reduce disposable water, reduce water consumption rate increase electricity generation and water storage reservoir more than three benefits together, the annual average increase generating capacity 54,mbt schuhe günstig,900,000 kW-h. Annual average power generation accounted for 2.86%, 10 years to increase generating capacity to 549 million kW ・ h, another. Increase utilization efficiency is immeasurable. 4 Conclusion economic operation is to control the current water level changes and improvement, whether it is wet, the average year, dry year,ecco golf shoes, can make the station a scientific and reasonable to run. Into the attack, or retreat to safety, is a more suitable station run. Economic operation, the actual work needs to continue to explore and improve, and gradually move to the optimal operation mode. |
