Machine, the impeller of the hydraulic turbine, gear train, generating set, generator, rectifier, energy storage accumulator jar, inverter, power plant building, conveying
Electric equipment is constituted, it is characterized in that:The check dam of existing water-power plant, diversion tunnel, forebay, pressure pipe, the hydraulic turbine,
On the basis of generating set, power plant building, conveying electric equipment composition, in the case where raw water turbine flow of inlet water, flow velocity are constant,
Water-power plant is by transforming the hydraulic turbine, the structure of generating set and layout, by hydraulic turbine tail water water drain groove depth
It is appropriate to deepen, transformation regulation hydroturbine water intake nozzle angle, by the hydraulic turbine of former minor diameter dismantle should not, be replaced with major diameter
The hydraulic turbine, hydraulic turbine diameter increases the piece number of impeller, and the impeller arc of the hydraulic turbine, bucket shape manufacture are achieved in that more
Energy, turbine shaft socket heights are appropriate, and the increase of hydraulic turbine diameter makes the increase of hydraulic turbine gravity, and the increase of hydraulic turbine diameter makes water wheels
Machine impeller is increased by waterpower, needs hydraulic turbine or so bearing block reinforcement, because the increase of hydraulic turbine diameter increases hydraulic turbine girth
Plus, hydraulic turbine girth increase makes rotational speed of water turbine slack-off, and rotational speed of water turbine is slack-off to be reached by gear train or gear-box raising speed
Rated speed, by former small power generator assembling and dismantling fall should not, be replaced with the powerful generating set matched, powerful hair
On the appropriate surface-based horizontal line of group of motors, water-power plant passes through check dam, diversion tunnel, forebay, pressure pipe
Produce potential energy → valve switch control hydroturbine water intake → speed regulator control stator mechanism acting → stator mechanism controls hydraulic turbine
The impeller of flow of inlet water flow velocity → hydraulic turbine is by under the impulsion of waterpower, and → promoting the hydraulic turbine to rotate → increases kinetic moment → drive tooth
Wheel group variable speed → drive generating set presses rated speed rotation → regular alternating current → of electrical power generators → production and power network;Or
Person, water-power plant produces potential energy → valve switch by check dam, diversion tunnel, forebay, pressure pipe and controls the hydraulic turbine
The impeller of water inlet → speed regulator control stator mechanism acting → stator mechanism controls hydroturbine water intake flow velocity → hydraulic turbine by
→ promote the hydraulic turbine to rotate → under the impulsion of waterpower and increase kinetic moment → drive gear train variable speed → drive generating set by volume
Determine rotating speed rotation → electrical power generators → production alternating current → rectifier rectification production direct current → direct current to give birth to by inverter
Produce regular alternating current and power network;Or, water-power plant produces potential energy by check dam, diversion tunnel, forebay, pressure pipe
→ valve switch control hydroturbine water intake → speed regulator control stator mechanism acting → stator mechanism controls hydroturbine water intake flow
The impeller of flow velocity → hydraulic turbine is by under the impulsion of waterpower → promoting the hydraulic turbine to rotate → increases kinetic moment → drive gear train change turn
Speed → drive generating set is by rated speed rotation → electrical power generators → production alternating current → rectifier rectification production direct current
→ direct current produces regular alternating current and power network to energy storage accumulator jar charging → direct current electricity output → by inverter;Above-mentioned waterpower
Power station can be reduced to hydroturbine water intake flow, water consumption is reduced and transformed, the hydraulic turbine of former minor diameter is dismantled should not, more
Change the hydraulic turbine of major diameter into, primary group of motors is retained, so save generator set device expense, its generation technology method is same
It is upper identical;Its details can change the present invention according to actual needs;
The process that electrical power generators obtain energy is exactly the process for overcoming reluctance force torque, the i.e. moment of resistance, and the hydraulic turbine is rushed by waterpower
The magnitude relationship of dynamic lower rotation, i.e. kinetic moment, kinetic moment and the moment of resistance is exactly the magnitude relationship of abbreviation generator energy conversion, two
The relation of person is to balance, i.e. kinetic moment=moment of resistance=power F1 × arm of force L1=power F2 × arm of force L2, in formula:Power F1 is water wheels
The impeller of machine is by waterpower, and arm of force L1 is the radius power arm of the hydraulic turbine, and power F2 is the resistance that electrical power generators are moved, and arm of force L2 is
The resistance arm of generator, the arm of force and power are directly proportional, and the electric energy of the more big corresponding generation of kinetic moment is bigger, so, in water flow
In the case of reduction, energy transformation ratio is improved in water energy conversion process by the hydraulic turbine, the energy of the hydraulic turbine of large radius turns
Rate is several times of energy, the Shi Jibei of the hydraulic turbine of minor radius, so, improves generated energy, reduces cost of electricity-generating, improves economic effect
Benefit;
The invention of water-power plant is the raising for promoting social productive forces for solving practical problems, and great number is provided for investor
Return;The present invention in actual use, will select water-power plant to the hydraulic turbine, generating set according to actual conditions
Structure and layout are transformed, and various technical methods as needed can intersect, exchange, increasing, reduce and use;The present invention is all
Title may be variant with reality, should be according to actual name;Material used in the present invention can change according to actual needs;This
All numerals of invention, quantity can change according to actual needs;All shapes of the present invention according to actual needs can
Change;All parts of the present invention can change according to actual needs;The figure of accompanying drawing of the present invention all may be used according to actual needs
To change.
