Description
Technical field
The utility model belongs to automation field, and in particular to a kind of medium and small water-power plant water wheels aperture speed governing knot
Structure.
Background technology
Hydroelectric generation is to be located at water of the eminence with potential energy using river, lake etc. to flow to lower, by potential energy contained therein
The kinetic energy of the hydraulic turbine is converted into, then using the hydraulic turbine as motive power, the process that pushing generator produces electricl energy.It is hydroelectric basic
Principle is to utilize the height of water, coordinates hydrogenerator unit to produce electric power, that is, switchs to the machines of water wheels using the potential energy of water
Tool energy, then with mechanical energy pushing generator, and obtain electric power.Scientists are with the natural endowment of this height of water, effective profit
With stream power engineering and mechanical-physical etc., arrange in pairs or groups meticulously to reach highest generated energy, for people to use cheap and free of contamination electricity
Power.
Because the voltage of power that hydraulic power plant is sent is relatively low, distant user is conveyed to, just must be by voltage
Increase by transformer, then the electric substation of user concentration zones is transported to by empty frame transmission line of electricity, be finally reduced to suitable home-use
Family, the voltage of factory's electrical equipment, and each factory and family are transported to by distribution wire.And user removes during electricity consumption and wants
Ask power supply safety outer, also there are very strict requirements to power grid power quality.Provided by China's power department, the volume of power grid
It is 50Hz to determine frequency, and for the middle minor scale power net in China, system loading fluctuates the 5%-10% for reaching its capacity sometimes.Electric power
The continuous change of system loading, result in the fluctuation of system frequency, therefore, it is necessary to constantly be adjusted according to water flow or pressure size
The aperture of guide vanes of water turbine is saved, so as to adjust the output power of generating set, maintains the generated energy of unit, here it is hydraulic turbine tune
The basic task of section, and the fluctuation of system frequency is intuitively accordingly the rotating speed of the hydraulic turbine, is externally the hydraulic turbine

The frequency of system is influenced, therefore, for medium and small water-power plant, with greater need for the aperture of great care guide vanes of water turbine, or even
The rotating speed of flywheel is monitored, so as to ensure the stabilization of system frequency.
The control of traditional guide vanes of water turbine aperture mainly by manually completing, its when starting generator and being worked,
By generating operation personnel, manually rotation manual wheel disc makes guide vanes of water turbine reach certain position first, and observes generator
Frequency values are 46-48Hz scopes, are then successfully established after voltage repeatedly continual manual rotation manual wheel disc to adjust water wheels
Machine leads leaf divergence, so as to coordinate the grid-connected conveying electricity of success for ensureing generator whole work process.Whole process is by personnel
Adjusting manually, complete unit start, during the adjustment of active power of output is weighed, response speed is slow, efficiency is low, and to electricity
Net causes fluctuation big.When particularly generating set has a power failure suddenly in normal operation, generator losing load driving can be caused,
After unit demagnetization and breaker open operation, while also need to protect machine using the aperture of governor high speed closing guide vanes of water turbine
Group.Come manual demagnetization, breaker open operation and operation governor closing guide vanes of water turbine aperture by personnel in the case of driving to show
But following three points security risk can be brought to gen-set and grid equipment and operating personnel：1. set drive part
Centrifugal force can be doubled and redoubled, so generator amature, guide vane, flywheel may be caused to loosen the danger that deformation sets disengaging,
Seriously affect unit safety；2. rotating speed rises serious aggravation after driving overlong time, unit radially wobbles and vibrates, and aggravates axis
The load held, so as to destroy bearing, violent vibration is also possible to the fracture for making some support parts of unit and foundation bolt, damages
Unit and the safety of workshop personnel；3. after unit driving, there is no demagnetization, killer switch there is no separating brake, machine if there is unit
The situation that group guide vane opening is not closed in time, can make the serious overvoltage of generator, the insulation safety of unit be endangered, to same electricity
Electrical equipment on circuit causes excessive pressure damages.Therefore, for above-mentioned various situations, from just needing to guide vanes of water turbine at all
Aperture carry out accurate control, the rotating speed of stable water wheels machine is carried out with this, so as to ensure the stabilization of system frequency.
