Abstract

The invention belongs to the field of hydroelectric generation technologies, and discloses an operation method of a vertical water turbine power generation device. A switch of a water diversion pipe and a switch of a flow adjusting device are turned on step by step for discharging water so that the amount of water flowing into a water chamber can be larger than that of discharged water of solenoid rotors, the water retains inside the water chamber, the whole water chamber is filled with the water, and a generator reaches a rated speed (n revolutions/ minute); the flow adjusting controller of the device is started to adjust the flow repeatedly so that the water flow can be kept stable, and the generator can be kept stable at the rated speed (n revolutions/minute). It is prevented that instant surge impacts damage a water turbine, obtained input dynamic energy is large, the water turbine operates stably, and voltage output is stable.

Description

The operation method of vertical turbine electricity generating device

Technical field

The invention belongs to technical field of hydroelectric generation, relate to the operation method of vertical turbine electricity generating device.

Technical background

The turbine power generating device applying date is on April 1st, 2015, and the present invention is the divisional application of a kind of vertical turbine electricity generating device wherein, therefore the content related in turbine power generating device application is applicable to the present invention.

Summary of the invention

The object of the invention is: open one can prevent momentary surges and impact, and makes vertical turbine electricity generating device smooth running, the operation method of voltage stable output.

The present invention is achieved through the following technical solutions:

The operation method of vertical turbine electricity generating device:

(1), the continuous step switch of opening the device of aqueduct open and close and adjust flux discharges water, and makes the water yield in inflow hydroecium be greater than the excretion of screwed pipe rotor, occurs hydropexis hydroecium and be full of whole hydroecium space, generator arrival rated speed n rpm;

(2), the adjust flux controller of Restarter, implement to regulate back and forth to flow, make water flow keep stable, generator also keeps being stabilized in rated speed n rpm.

Owing to taking abovementioned technology, the operation method of vertical turbine electricity generating device of the present invention can obtain following technique effect:

1, continuous step is opened and is discharged water, and can prevent current and impact the momentary surges of water turbine.

2, hydropexis hydroecium be full of whole hydroecium space, obtains input energy large, makes active force that every bar screwed pipe water inlet unit area obtains substantially equal, water turbine smooth running, voltage stable output.

3, suitable water flow is easily found.

4, its manipulation process easily adopts computer to control.

Accompanying drawing explanation

Below in conjunction with Figure of description, the present invention is described in further detail.

Accompanying drawing is a kind of schematic diagram of vertical turbine electricity generating device.

1. dam, the 2. device of open and close and adjust flux, 3. intakeport, 4. aqueduct, 5. dynamo bearing, 6. rotating shaft, 7. generator, 8. block bearing, 9. hydroecium, 10. diversion cone, 11. runners, 12. screwed pipes, 13. draft tubes, 14. bearing bases, 15. block bearings, 16. basements, 17. bulkheads, 18. casing water inlets, 19. casings.

Embodiment

(1), the continuous step switch of opening the device of aqueduct open and close and adjust flux discharges water, and makes the water yield in inflow hydroecium be greater than the excretion of screwed pipe rotor, occurs hydropexis hydroecium and be full of whole hydroecium space, generator arrival rated speed n rpm;

(2), the adjust flux controller of Restarter, implement to regulate back and forth to flow, make water flow keep stable, generator also keeps being stabilized in rated speed n rpm.

It is exactly that waterdrainage amount slowly increases that the switch that continuous step opens the device of aqueduct open and close and adjust flux discharges water, and is not once put into peak rate of flow, prevents momentary surges and impacts and damage water turbine.The water yield flowed in hydroecium is greater than the excretion of screwed pipe rotor, there is hydropexis hydroecium and be full of whole hydroecium space, at this moment be added in hydroecium water inlet pressure can by the water in airtight hydroecium by original size to all directions transmission, the active force that so every bar screwed pipe water inlet unit area obtains is substantially equal, the imbalance of screwed pipe centrifugal force can be offset, make vertical turbine electricity generating device smooth running, voltage stable output.

Claims (1)

1. the operation method of vertical turbine electricity generating device, is characterized in that:

(1), the continuous step switch of opening the device of aqueduct open and close and adjust flux discharges water, and makes the water yield in inflow hydroecium be greater than the excretion of screwed pipe rotor, occurs hydropexis hydroecium and be full of whole hydroecium space, generator arrival rated speed n rpm;

(2), the adjust flux controller of Restarter, implement to regulate back and forth to flow, make water flow keep stable, generator also keeps being stabilized in rated speed n rpm.
