Description
Technical field
The utility model relates to a kind of water power plant power generating equipment, particularly a kind of double runner combined horizontal hydraulic generator unit.
Background technique
At present, water power plant hydraulic generator machine equipment all is the supporting generator of a water turbine (runner), and this point can be confirmed from the catalogue of numerous hydro-electric power generating equipment manufacturer and webpage." also convincingly demonstrate this traditional form small hydropower station power generating equipment handbook (host machine part) (Bai Lin chief editor), " hydraulic generator unit operation and maintenance " books such as (Jiang Jing of Hohai University China compile) from what hydraulic and electric engineering publishing house published.
Mainly there is following problem in traditional hydraulic generator unit coordinative composition of equipments: 1, generator is under the situation of band different load, and efficiency change is little, promptly can move at high efficient area more reposefully.Water turbine is then different, generally moves under the rated load situation, and its efficient is than higher, when departing from rated load operation, and decrease in efficiency, particularly when load was lower than 50% rated load, efficient obviously descended, and with phenomenons such as cavitation, vibrations, the harm unit.And water power plant, the particularly water power plant of adjusting function difference, owing to come the water yield inhomogeneous, unit usually will move under low-load, and generating efficiency is low, and unit durability is short.2, traditional water turbine, i.e. rotary wheel of water turbine, the head that it adapted to be subjected to certain limit restriction.When reservoir drawdown is big, select suitable water turbine just quite difficult, selected traditional type water turbine usually is to move under bad operating mode, inefficiency, and produce phenomenons such as cavitation and vibration, the harm unit, influence life of equipment, thereby influence the power station benefit.
Summary of the invention
Technical problem to be solved in the utility model has two aspects: 1, solve the plant without storage because no reservoir is regulated, come the water yield inhomogeneous, unit often can not move under rated load, and generating efficiency is low, the technical problem that unit durability is short.2, solve the power station at dam toe and be difficult to the appropriate technology problem owing to reservoir drawdown makes the unit head greatly.
The purpose of this utility model just provides the form of a kind of two water turbine of employing and a generator combination, has widened the accommodation of unit, has improved the hydraulic generator unit of the operational efficiency of unit.
The utility model can be realized in the following manner: water turbine is by flywheel and clutch connecting generator, and stretch out the axial other end of generator main, connects another water turbine by clutch.Clutch connects another water turbine by flywheel.Flywheel can connect water turbine by the speed changer (not shown).
The utlity model has following advantage and beneficial effect: if 1 this unit is applied in water yield variation power station greatly, in this case, the generator rated capacity is two water turbine rated capacity sums.Unit can change the different operating scheme of formulation according to the water yield of coming in power station, when coming the water yield bigger, two water turbine put into operation simultaneously, when coming the water yield hour, withdraw from a hydraulic turbine operation, thereby unit is moved under greater efficiency, avoided prolonging unit durability owing to phenomenons such as the unit cavitation that operation causes under poor efficiency district operating mode for a long time, vibrations.If 2 this units are applied in head variation power station greatly, in this case, select a water turbine to be adapted to the operation of high head section, another then is adapted to the operation of low water head section, and it is identical with a water turbine capacity capacious that generator capacity is then selected.When the power station when the high head section is moved, the water turbine of high head section puts into operation, the water turbine of low water head section is out of service; When the power station when the low water head section is moved, the water turbine of low water head section puts into operation, the water turbine of high head section is out of service.Thereby improve the scope that unit adapts to head, unit is moved under greater efficiency, and solved to a certain extent, prolong unit durability owing to unit is departing from cavitation, the oscillation phenomenon that operation causes under the high efficient area operating mode for a long time.3, the utility model has and reduces investment outlay and the advantage of flexible operation.4, the utility model is suitable for horizontal water turbine and generator, and selected combined equipment all is conventional and is ripe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the drawings, 1 water turbine, 2 flywheels, 3 clutches, 4 generators, 1 ' water turbine, 2 ' flywheel, 3 ' clutch.
Embodiment
Please read Fig. 1, water turbine 1 is by flywheel 2 and clutch 3 connecting generators 4, and generator 4 main shafts stretch out to the other end, by clutch 3 ' connection water turbine 1 '.Clutch 3 ' by flywheel 2 ' connection water turbine 1 '.Flywheel 2 ' can by the speed changer (not shown) connect water turbine 1 '.The model of two rotary wheel of water turbine can be different, also can be identical, and size can be identical, also can vary in size.The parameter of selecting rotary wheel of water turbine is according to factor such as the condition in water power plant and the method for operation and definite.Two water turbine can be worked simultaneously, pull down clutch, also can any one work independently.The input of two water turbine realizes that with withdrawing from the employing clutch clutch is normally used to be coupling, generally is to shut down to finish.When rotational speed of water turbine and generator speed identical match, water turbine and generator adopt coaxial direct connection, when rotating speed not simultaneously, nonsynchronous water turbine one end can adopt the speed changer (not shown) to synchronize them.Generally speaking, select the water turbine rotating speed all identical as far as possible with generator.Two water turbine of unit can a shared pressure tube, pressure tube separately also can be arranged, but generator has only one to be shared, and the layout of pressure tube is decided on the concrete condition in water power plant.
Example: certain water supply project, water supply flow are 2m
3/ s～2.2m
3/ s for making full use of waterpower resourses, plans to build water power plant behind the dam, head 28m～53m.Because this power station flow is relatively stable, and the head excursion is big, presses traditional approach and select unit as follows:
40m～53m head section: water turbine HL220-WJ-60 rotating speed 750r/min
Generator SFW800-8/990 outlet voltage 6.3Kv
28m～40m head section: water turbine HL260-WJ-60 rotating speed 750r/min
Generator SFW500-8/1180 outlet voltage 0.4Kv.
Select unit as follows by the utility model mode:
40m～53m head section: water turbine HL220-WJ-60 rotating speed 750r/min
28m～40m head section: water turbine HL260-WJ-60 rotating speed 750r/min
Two water turbine are adapted to different head section operations respectively
Shared auxiliary generator SFW800-8/990 outlet voltage 6.3Kv.
The unit that the utility model and traditional approach are selected relatively has following advantage:
1, saves one in generator; 2, avoid different generator outlet voltage, electrical equipment is simplified; 3, save the factory building arrangement areas.
Relatively stable when power head, when changes in flow rate is big, also can use double runner combination water turbine generator, but different with last example be in this case, two water turbine can move simultaneously, also can any machine isolated operation.
