Description
Technical field
The present invention relates to the technical fields of upwind wind power generating set control, refer in particular to a kind of upwind wind-power electricity generation
The control method of unit.
Background technique
During typhoon occurs, power grid is generally in failure or off-position.Under traditional wind power generating set control model,
During typhoon occurs, if wind power plant is configured without backup power supply, the yaw system of wind power generating set will be in the lock state always,
It cannot achieve and wind vector is followed, unit will carry huge load, therefore, for the safety for ensuring unit, typhoon zone
The pylon of unit is typically designed to strongr, in turn results in being significantly increased for complete machine cost.If wind power plant increases backup power supply
Configuration (during ensuring typhoon, unit has effective power source, executes yaw system in real time to wind), the whole construction of same project
Cost will also be significantly increased.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology with it is insufficient, consideration combat typhoon the limitation of type Wind turbines cost because
Element proposes a kind of control method of upwind wind power generating set, it is intended to solve traditionally wind direction wind power unit typhoon
The problem that load is excessively high under mode and crew qiting backup power supply cost is excessively high.
To achieve the above object, a kind of technical solution provided by the present invention are as follows: control of upwind wind power generating set
Method, specific as follows including the control under normal mode and typhoon model:
Under normal mode, i.e., under non-typhoon model, wind power generating set is controlled by upwind, unit uses power
The active yawing system of power supply, real-time tracking wind vector, it is ensured that cabin and wind direction angle guarantee unit generation amount always at 0 °
It is optimal, it is standby or shut down in the case of, propeller pitch angle is in 90 ° of positions；
It under typhoon model, presses wind direction and wind power generating set is controlled, before entering typhoon model: need to first pass through dynamic
Power power supply adjustment blade pitch angle is in 90 ° of positive full feathering states, then adjusts cabin and practical wind by electrical source of power active yawing
It is in 180 ° to angle, then adjusts blade pitch angle and be in -90 ° of anti-full feathering states；And after formally entering typhoon model: unit
Yaw no longer receives electrical source of power control, and turbines vane is in locking always and impeller is in idling conditions always, unit according to
Wind load feature carries out passive yawing adjustment, it is ensured that and cabin and wind direction angle are always at 180 °, so that during typhoon occurs, machine
Group load is in relatively low level always.
Compared with prior art, the present invention have the following advantages that with the utility model has the advantages that
1, can be realized by this control method it is at a disadvantage to unit working condition under upwind unit typhoon model, because
This, both can guarantee the generated energy of unit normal running conditions, meanwhile, the load under unit typhoon model can be made to be effectively reduced, reached
The target of cost is reduced to tower weight is reduced in turn.
2, by this control method, it can be achieved that upwind unit can also possess the passive yawing function of lower wind direction unit, with
This removes the configuration of backup power supply from, reduces project entirety construction cost.
Detailed description of the invention
Fig. 1 is the control logic schematic diagram of the method for the present invention.
Fig. 2 is schematic diagram of the upwind unit forward direction to wind.
Fig. 3 is upwind unit reversely to the schematic diagram of wind.
Specific embodiment
The present invention is further explained in the light of specific embodiments.
Upwind wind power generating set is widely used with the feature that its catch wind efficiency is higher than lower wind direction unit.And lower wind direction
Wind power generating set is because of its intrinsic structure type, and passive yawing (can be certainly without electrical source of power under the conditions of having the function of typhoon
It is dynamic to wind) and load the advantages of being lower than upwind unit.In conjunction with the advantageous characteristic of this two kinds of types, the present embodiment proposes one
Kind is directed to the control method of upwind wind power generating set, is taken into account with realizing to two kinds of type advantageous characteristics, control logic is such as
Shown in Fig. 1, method main points are as follows:
Under conventional (non-typhoon) mode, wind power generating set (as shown in Figure 2) is controlled by upwind, normal power generation
Under operating condition, unit uses the active yawing system of electrical source of power, real-time tracking wind vector, it is ensured that cabin and wind direction angle are always
At 0 ° or so, guarantee the optimal of unit generation amount, under standby or shutdown mode, propeller pitch angle is in 90 ° of positions.
Under typhoon model, presses wind direction and wind power generating set (as shown in Figure 3) is controlled, into before typhoon model:
1) blade pitch angle is adjusted by electrical source of power and is in 90 ° of positive full feathering states；2) cabin is adjusted by electrical source of power active yawing
It is in 180 ° with practical wind direction angle；3) then adjustment blade pitch angle is in -90 ° of anti-full feathering states.Formally enter typhoon model
Afterwards: set yaw no longer receives electrical source of power control, and turbines vane is in locking always and impeller is in idling conditions, machine always
Group carries out passive yawing adjustment according to wind load feature, it is ensured that cabin and wind direction angle are always at 180 °, so that the phase occurs for typhoon
Between, rack load is in relatively low level always.
Can realize by the method for the invention it is at a disadvantage to unit working condition under upwind unit typhoon model, therefore,
Both it can guarantee the generated energy of unit normal running conditions, meanwhile, the load under unit typhoon model can be made to be effectively reduced, reach drop
Low tower weight reduces the target of cost in turn.In addition, can also realize upwind unit also can possess the passive of lower wind direction unit
Driftage function removes the configuration of backup power supply from this, reduces project entirety construction cost, has practical application value, is worth pushing away
Extensively.
Embodiment described above is only the preferred embodiments of the invention, and but not intended to limit the scope of the present invention, therefore
All shapes according to the present invention change made by principle, should all be included within the scope of protection of the present invention.
