Embodiment
Below in conjunction with figure, the specific embodiment of the present invention is described further.
As shown in Figure 1, blower fan machine group rotor control response speed is fast, and the power-adjustable that can provide is less, the duration is shorter, is easily subject to the impact of operating states of the units.
As shown in Figure 2, blower fan set pitch control regulating and controlling ability is comparatively strong, and adjustable range is comparatively large, but by blade inertia effects, response speed is comparatively slow, operates in non-optimal point, causes wind power generation benefit to reduce.
As shown in Figure 3, energy-storage system fast response time, the blind area not being subject to the restriction of Wind turbines running status, filling up the control of Wind turbines rotor and the control of change oar, but cost is higher.
As shown in Figure 4, line voltage U and the frequency f status data of the running state data of wind energy turbine set, the running state data of energy-storage system and wind accumulation grid integration point is gathered.The running state data of wind energy turbine set comprises voltage, electric current, active power, reactive power.The running state data of energy-storage system comprises the state-of-charge of active power, reactive power, battery pack.The above-mentioned data collected are delivered to wind accumulation DAM parametric controller, wind accumulation DAM parametric controller according to the instruction of dispatching of power netwoks or electric power system frequency modulation demand, by the data acquisition of wind accumulation and Monitor and Control platform to air-out accumulation power stage variable quantity reference value P
g, participate in the frequency adjustment of electrical network.
From the angle of power system frequency and quality of voltage and stability, wish wind accumulation active power exporting change amount P
gthis part energy steadily reliable, this part energy can by Wind turbines rotor speed control, Wind turbines award setting, and energy-storage system provides.Described rotor control method is the rotating speed by controlling electric generating set rotor, and the deceleration making it of short duration or acceleration, to discharge or to store certain energy.Described variable pitch control method is the propeller pitch angle by controlling Wind turbines, changes the Windward angle of fan blade, and then changes the mechanical output of blower fan input, to realize the change of power output.Described energy-storage system, by controlling the power instruction of the grid-connected Power Conditioning Unit of energy storage, makes the I/O of energy-storage system active power change, to realize the object of power adjustments.The energy that rotor control method provides is provided by the temporary variations of rotor speed, must carry out rotating speed recovery after of short duration acceleration or deceleration, and make the duration of its power stage shorter, regulating power is limited; And by the restriction of natural conditions, the energy that variable pitch control provides can not stable supplying along with the fluctuation of wind speed.Energy-storage system can provide stable and lasting power, if but only depend on energy-storage system, the capacity configuration of energy storage can be made very large, and macroeconomic declines.The present invention fully utilizes that Fig. 1-Fig. 3 Wind turbines rotor controls, the power adjustments characteristic of Wind turbines variable pitch control and energy-storage system, coordinate the control procedure between three, optimize energy that distribution rotor controls to provide, energy that variable pitch control can provide, and the energy that energy-storage system can provide.
The step of cooperation control Wind turbines rotor of the present invention, Wind turbines propeller pitch angle and energy-storage system is:
A) first, wind accumulation DAM parametric controller sends rotor speed control instruction to part or all Wind turbines, this instruction issuing, to the rotor controlling unit of Wind turbines, carries out acceleration or deceleration control to rotor, makes the variable quantity P of its power output

Fig. 5, for adopting wind accumulation control method for coordinating, by the rotor power of wind accumulation optimization output power distribution, becomes oar power and energy storage power schematic diagram.Can find out, rotor controls by controlling spinner velocity change, and release/absorption portion energy in short-term, can respond the changed power demand of Wind turbines fast, provide the moment of inertia being similar to conventional rack; But because rotor speed recovery process subsequently can absorb/release portion energy, thus the regulating power of this mode is limited.Variable pitch control, by controlling the propeller pitch angle of fan blade, regulates the input mechanical output of blower fan, thus follows the tracks of the power output change demand of Wind turbines; This mode power regulating range is comparatively large, and duration is longer, but running of wind generating set is at non-maximum power point, there is certain power generation loss, and owing to there is the change oar link of machinery, response speed is also slower.In addition, the rotor of Wind turbines controls and becomes the running status that oar controls all inevitably to be limited by blower fan, and especially wind speed frequently and be difficult to the impact of the change predicted, Shortcomings in the confidence level of reserve capacity.Energy-storage system fast response time, control flexibly, can provide stable and lasting power, if but only adopt energy-storage system, stored energy capacitance can be made to configure very large, macroeconomic declines.Energy-storage system is applied to wind energy turbine set by the present invention; to control with the rotor of Wind turbines and variable pitch control is coordinated mutually; comprehensive utilization rotor control response speed is fast, change oar controls duration length and energy storage controls feature flexibly; its comprehensive power output effect is made to meet rapidity, stationarity and persistence requirements; for wind accumulation provides reliable and stable reserve capacity to support; make wind energy turbine set possess frequency regulation capability and the reserve capacity of similar conventional rack, improve the rear stability of power system of wind electricity large-scale access and the quality of power supply.
The present invention's power adjustments in the generating of wind accumulation has higher technology economy advantage, required energy storage configuration capacity greatly reduces, and avoid Wind turbines frequently to participate in system power and regulate, unit loss reduces, life, improves the economic benefit that wind accumulation is run.
