在高水头电站中,为满足技术供水水压的要求,经常采取多种减压措施,而利用可调式射流泵进行减压的技术供水系统,在国内还较为少见。文中结合越南儒桂水电站,采用可调式射流泵技术供水方式,介绍了其技术供水自动控制系统的构成、具体实现及控制策略。实验和实践验证了该方法的有效性、可行性及经济性,为高水头水电站技术供水提供了一种新的可行方法。
In the high head station, to meet the technical requirements of water pressure, often take a variety of decompression measures, and the use of adjustable jet pump technology for water supply system, is still relatively rare in China. In this paper, combining with the Ruizhou-Gui Hydropower Station in Vietnam, adopting the technology of adjustable jet pump water supply, the composition, concrete realization and control strategy of its automatic water supply control system are introduced. Experiments and practices have verified the effectiveness, feasibility and economy of this method and provided a new feasible method for water supply of high head hydropower station.
