Technical field
The present invention relates to a kind of hydraulic power plant residue energy and utilize method and apparatus.Be mainly used in the surplus energy utility in power station and the dilatation of building a station.
Background technology
At present, the hydroelectric generation unit in most of power stations is the potential energy generatings that utilize high-order water, and the hydraulic turbine generally is loaded on the following orientation of dam.And the kinetic energy of the water of dam upper position is not fully used, and causes the waste of the water resource energy.It then is the upper position that is loaded on dam that the hydroelectric generation unit in the power station of part is also arranged, and the water after the generating still has a large amount of potential energy not to be fully used, and causes the waste of the water resource energy equally.How developing the complementary energy of this part, is a current important and long-term problem.
Summary of the invention
The object of the present invention is to provide the hydraulic power plant residue energy of the potential energy generating of the upper position kinetic energy that makes full use of water under a kind of situation of the potential energy generating that does not influence water or the water after the generating to utilize method and apparatus.
The technical solution adopted for the present invention to solve the technical problems is; (forebay place or aqueduct entrance) installs an additional water group of motors near the upper position water inlet of following orientation water power device, this additional water group of motors is the low head water turbine TRT, this turbine power generating device mainly utilizes the kinetic energy running of water, can be funneling big vacuum mixed flow or axial-flow wheel generating set or a kind of double click type expansion crawler type stator Waterwheel-type hydraulic generator unit.Also the following orientation of position water power device (delivery port improvement water level place or the available geographical position of irrigation canal) installs an additional water group of motors up, and this additional water group of motors is one group of low water head dragon car group hydraulic generator unit.
The invention has the beneficial effects as follows: can make full use of the energy of water resource, but more original water potential energy generating increase-volume 40%--50% that only utilizes once.
