Abstract
The invention relates to a hydraulic wind power generation set and an energy layered-controlled low-voltage ride through control method. When a power grid voltage drops due to a fault, top-layer control is that a pitch angle of a wind turbine is controlled by a pitch angle controller so as to reduce wind energy capturing; intermediate-layer control is that control on a pivot angle of a variable motor is realized by a rotational speed controller, a high-voltage pressure of a hydraulic system is reduced, so that the rotational speed of a fixed displacement pump is increased, and residual power is converted to kinetic energy of a wind wheel; and bottom-layer control is that the opening degree of a proportional throttle valve is controlled by a power controller, residual energy is converted to thermal energy, and finally, storage, consumption and release of residual energy are realized during the low-voltage ride through process. The transmission energy of the machine set is controlled by pitch adjustment, wind abandoning, inertia energy storage of the wind turbine and proportional throttling coordinated control, the residual energy of the machine set is suppressed from a source, and the energy loss during the low-voltage ride through process is also effectively prevented; and meanwhile, by adding a proportional throttling stage, the system response is sped up, and the system is flexible in action.
Description
Technical field
The present invention relates to technical field of wind power generation, especially a kind of Wind turbines and low voltage traversing control method.
Background technology
The energy is the basis of human survival and development, and with social development and progress, the mankind continue to the demand of the energy
Increase, wind energy as important and the most ripe renewable energy technologies, have reserves enrich, be distributed wide, renewable, pollution-free
Etc. characteristic, the important directions that wind energy is Renewable Energy Development how are made full use of.
Wind-driven generator can be divided into gear-box type, direct-drive type and fluid pressure type from the point of view of drive system.Hydraulic Wind turbines
Widely paid close attention to as wind-power electricity generation of new generation equipment, compared with conventional types, on the one hand, replaced with hydrostatic transmissions
The positive drive of most of type middle gear case, it is to avoid the high problem of gearbox drive fault rate.On the other hand, using liquid
Pressure Flexible Transmission solves the problems, such as that in permanent magnet direct-drive type, magneto volume is excessive, copper consumption is high, manufacturing cost is high.
Increasingly increase with proportion in energy supply for the wind-power electricity generation, for ensureing the stability of power system, wind turbine
The grid-connected specification of group is gradually improved, and low voltage ride-through capability is one of basic demand to grid type unit, when event in electrical network
When barrier leads to that line voltage is of short duration to be fallen, synchronous generator set end voltage instantaneously falls, and electromagnetic torque accordingly reduces, and variable displacement motor
Output torque is constant, and that is, electromotor input torque is constant, just creates torque ripple and lead to rotor speed ripple so on rotor
Dynamic.If not being controlled by, each parameter all can meet or exceed secure setting and lead to Wind turbines off-grid.
China to LVRT Capability of Wind Turbine Generator process specific requirement is: 1) Wind turbines in wind energy turbine set have grid-connected

Composition, control unit gathers the voltage signal of electrical network, outputs a control signal to flow control valve, to control pressure duct and low pressure
Fluid flowing between pipeline, completes low voltage crossing.There is variable displacement motor pivot angle and flow control valve valve port opening in the method
Two control variable, control ratio is more flexible, but in control process, energy loss is huge, is not also specifically described and controlled in this patent
The control method for coordinating of two control variable and energy allocative decision in journey.
In Chinese patent cn104362699a, University On The Mountain Of Swallows proposes a kind of hydraulic Wind turbines based on energy stores
Low-voltage ride-through method, when grid voltage sags, energy distribution and storage principle are that variable displacement motor swinging angle control is preferential, and will
Residual amount of energy is stored in accumulator with hydraulic energy form.But the method need into one at the aspect such as response speed and reliability
Step improves.
In sum, existing hydraulic LVRT Capability of Wind Turbine Generator control method generally existing control variable single,
Response speed is slow, reliability is low and control process in two control variable control method for coordinating and energy allocative decision obscure etc. and to lack
Fall into.Therefore, need a kind of New die mould LVRT Capability of Wind Turbine Generator control method of proposition badly.
