The structured flowchart of the blower fan calling system of the wind energy turbine set that Fig. 2 provides for specific embodiment of the present invention.
Embodiment
For making those skilled in the art understand better technological scheme of the present invention, below in conjunction with accompanying drawing, the blower fan call method of wind energy turbine set provided by the invention and blower fan being called is to be described in detail.
Refer to Fig. 1, wherein show the flow process of the blower fan call method of the wind energy turbine set that first embodiment of the invention provides.
In step 110, the status parameter of each blower fan in the Real-time Collection wind energy turbine set.So-called status parameter at least comprise following parameter one of them: the temperature of Cumulative Elapsed Time, this continuous working period, accumulative standby time, this lasting standby time, critical component.So-called critical component can comprise generator, vane change device and current transformer, and in this case, the temperature T 3 of the temperature T 1 of generator, the temperature T 2 of vane change device and current transformer also can be confirmed as the status parameter of blower fan.
In step 120, determine the sequence parameter according to the aforesaid state parameter, and determine the blower fan calling sequence based on this sequence parameter.Wherein, the blower fan calling sequence can comprise operating unit calling sequence and standby unit calling sequence.So-called operating unit calling sequence refer to by wind energy turbine set all at the unit of operation according to the numerical values recited of the parameter that the sorts resulting unit calling sequence that sorted; So-called standby unit calling sequence refer to by wind energy turbine set all the standby units according to the numerical values recited of the sequence parameter resulting unit calling sequence that sorted.
Particularly, in step 120, when adopting a status parameter to determine the sequence parameter, this sequence parameter is this status parameter itself.When adopting a plurality of status parameters to determine the sequence parameter, for each status parameter assigns weight, and calculate the sequence parameter according to each status parameter and weight thereof.Alternatively, when adopting a plurality of status parameters to determine the sequence parameter, for each status parameter arranges priority, the status parameter that priority is high is set as the parameter that sorts, based on this sequence parameter, the corresponding blower fan in wind energy turbine set is sorted, that is, by the numerical value of the corresponding sequence parameter of each blower fan relatively, the corresponding blower fan in wind energy turbine set is sorted.In this sequencer procedure, if the numerical value of the corresponding sequence parameter of a plurality of blower fans equates, first described a plurality of blower fans are arranged side by side, and after the corresponding blower fan in wind energy turbine set all sorts, the sequence parameter is reset to the status parameter of the low grade of priority, and with this, described a plurality of blower fans is further sorted.By that analogy, finally to form complete blower fan calling sequence.
In step 130, call in wind energy turbine set corresponding blower fan and adjust its running state based on above-mentioned blower fan calling sequence, so that the working order of wind energy turbine set meets the demand of electrical network, for example, make the output power of wind energy turbine set meet the power demand of electrical network.
Particularly, in step 130, in the situation that wind energy turbine set needs power per liter and standby unit calling sequence to have the standby unit, based on standby unit calling sequence, call corresponding standby unit and adjust its running state; And in the situation that the standby unit in standby unit calling sequence still is not enough to the output power of wind energy turbine set is adjusted to target call after all calling, further be invoked at the unit of operation and adjust its running state according to the operating unit calling sequence, so that the working order of wind energy turbine set meets the demand of electrical network.Perhaps, in the situation that wind energy turbine set needs power per liter and standby unit calling sequence not to have the standby unit, be invoked at the unit of operation and adjust its running state based on the operating unit calling sequence, so that the working order of wind energy turbine set meets the demand of electrical network.
And, in described step 130, in the situation that power need to fall in wind energy turbine set, based on the operating unit calling sequence, call corresponding unit and adjust its running state; And in the situation that the unit in the operating unit calling sequence still is not enough to after all calling the output power of wind energy turbine set is adjusted to target call; further make the corresponding compressor emergency shutdown in this sequence based on this operating unit calling sequence again, so that the working order of wind energy turbine set meets the demand of electrical network.
Blower fan call method below in conjunction with the instantiation of wind energy turbine set power adjustments to wind energy turbine set provided by the invention is elaborated.In this example, the false wind electric field have 10 Fans unit G1, G2 ..., G10, and the specified output power of completely sending out of every unit is 1.5MW, the total specified output power of completely sending out of this wind energy turbine set is 15MW.In wind energy turbine set real-world operation process, for meeting the power demand of electrical network, need to constantly call the corresponding unit in wind energy turbine set and constantly change its running state, for example, for meeting the requirement of wind energy turbine set power per liter, need to enable the standby unit or raise the generated output at operating unit; Perhaps, fall the requirement of power for meeting wind energy turbine set, need to stop using or lower the generated output at operating unit.
In order reasonably to call the corresponding blower fan in wind energy turbine set, the first step, need the status parameter of each blower fan in the Real-time Collection wind energy turbine set.In this example, by the status parameter that gathers each blower fan in wind energy turbine set, know: the current total output power of this wind energy turbine set is 7.3MW, wherein has 3 unit G1, G2 and G3 completely to send out state in rated power; 3 unit G4, G5 and G6 are in limit power generating state; 3 unit G7, G8 and G9 are in holding state; 1 unit G10 is in shutting down maintenance state.Following table one shows the detailed status parameter information of each blower fan unit, and wherein, t1 is blower fan accumulated running time, and t2 is continuous working period (being designated hereinafter simply as this continuous working period) after enabling for this.
Table one:
Second step, determine the sequence parameter according to the status parameter collected, and based on this sequence parameter and ordering rule, the blower fan in wind energy turbine set sorted, to determine the blower fan calling sequence.Wherein, so-called ordering rule can refer to according to the numerical value of sequence parameter is ascending and sort or descending the sequence; So-called blower fan calling sequence can comprise operating unit calling sequence and standby unit calling sequence.
In this example, using this continuous working period as the sequence parameter, and according to this continuous working period ordering rule from short to long at operating unit, being sorted and being obtained the blower fan calling sequence in wind energy turbine set:, the operating unit calling sequence is G5, G4, G6, G3, G2, G1; Standby unit calling sequence is G7, G8, G9.Wherein, this continuous working period of each blower fan in standby unit calling sequence is zero, thereby these three standby units are arranged side by side.In fact, in actual applications, when gathering the fan operation state, can increase again the status parameter of relevant standby time, and, using this parameter as the sequence parameter that produces standby unit calling sequence, then according to standby time, ordering rule is from long to short sorted and is obtained standby unit calling sequence the standby unit in this wind energy turbine set.
The 3rd step, the current gross output of power demand by electrical network relatively and wind energy turbine set determines whether wind energy turbine set needs lifting/lowering power, and adjust demand and above-mentioned blower fan calling sequence according to power and call in wind energy turbine set corresponding blower fan and adjust its running state, so that the total output power of wind energy turbine set meets the power demand of electrical network.
Particularly, when electrical network needs power per liter, generally, preferentially enable the standby unit, and preferentially enable the unit that standby time is long when enabling the standby unit, the operating unit calling sequence is removed and be recorded to upgrade in time after the enabling states such as standby time of this unit by this unit simultaneously from standby unit calling sequence.If there is no the standby unit that can enable in standby unit calling sequence, preferentially call in the operating unit calling sequence shorter unit working time.In order to describe clearlyer, below come in two kinds of situation the power per liter process is elaborated.
Situation one: the output power that only by calling the standby unit, promotes wind energy turbine set.
For example, the current total output power of wind energy turbine set is 7.3MW, and the power demand of current electrical network is 10MW.By relatively finding out, the current total output power of wind energy turbine set is lower than the current power demand to wind energy turbine set of electrical network.For this reason, wind energy turbine set need to upwards promote 2.7MW by its gross output,, by calling corresponding blower fan in wind energy turbine set and adjusting its running state output power that wind energy turbine set is total, promotes 2.7MW that is.
Particularly, first enable the standby unit in standby unit calling sequence, for example, by each unit accumulated running time in standby unit calling sequence relatively, select and call the shortest unit of accumulated running time (being G9), and it is adjusted to the state of completely sending out, promote 1.5MW with the output power that wind energy turbine set is total, then upgrade the running state of unit G9, and it is deleted from standby unit calling sequence, it is charged to the operating unit calling sequence simultaneously; Then, again select and call the shortest unit of accumulated running time (being G7) in current standby unit calling sequence, and it is adjusted to the limit power generating state that output power is 1.2MW, then upgrade the running state of unit G7, and it is deleted from standby unit calling sequence, it is charged to the operating unit calling sequence simultaneously.Like this, only, by calling G9 and G7 in standby unit calling sequence, output power that can wind energy turbine set is total is promoted to 10MW by 7.3MW, thereby makes wind energy turbine set meet the power demand of electrical network.
Situation two: the output power that promotes wind energy turbine set by calling standby unit and operating unit.
For example, the current total output power of wind energy turbine set is 7.3MW, and the power demand of current electrical network is 13MW.By relatively finding out, the current total output power of wind energy turbine set is lower than the current power demand to wind energy turbine set of electrical network.For this reason, wind energy turbine set need to upwards promote 5.7MW by its gross output,, by calling corresponding blower fan in wind energy turbine set and adjusting its running state output power that wind energy turbine set is total, promotes 5.7MW that is.
Particularly, first call the standby unit in standby unit calling sequence,, call standby unit G7, G8 and G9 and it is adjusted to the state of completely sending out, output power that can wind energy turbine set is total promotes 4.5MW, then upgrades the running state of unit G7, G8 and G9, and it is deleted from standby unit calling sequence, it is charged to the operating unit calling sequence simultaneously, now in standby unit calling sequence, there is no the standby unit.After this, then call in the operating unit calling sequence at operating unit, that is, according to the sequence in the operating unit calling sequence, call successively unit G5 and G4, wherein, preferentially unit G5 is adjusted to and completely sends out state and make its output power promote 0.5MW; Again the output power of unit G4 is promoted to 0.7MW subsequently.Like this, by calling G7, G8 in standby unit calling sequence and G5 and the G4 in G9 and operating unit calling sequence, output power that can wind energy turbine set is total is promoted to 13MW by 7.3MW, thereby makes wind energy turbine set meet the power demand of electrical network.
By foregoing description, can find out, above-mentioned example is using this continuous working period as the sequence parameter, and determines the blower fan calling sequence based on this and carry out that blower fan calls.In actual applications, adopt this mode can avoid causing the electric component excess Temperature at its critical component place because the blower fan continuous working period is long and causing fault.In other words, when adopting this continuous working period blower fan sort and while calling, can reduce and even avoid the fault caused because of the electric component excess Temperature as the sequence parameter and according to the length of working time.
Be understandable that, in actual applications, also can sort to blower fan and call using accumulated running time as the sequence parameter and according to the length of accumulated running time.When adopting accumulated running time as the sequence parameter and according to the length of accumulated running time, blower fan sort when calling, can avoid unit the tired also initiating failure of equipment to occur because accumulated running time is long.In other words, adopt accumulated running time sort when calling as the sequence parameter and according to the length of accumulated running time, can reduce and even avoid because of equipment fatigue the fault that causes.
And, when adopting accumulated running time as the sequence parameter, the operating unit calling sequence sequentially is G5, G6, G4.Like this, for above-mentioned situation two, can call successively unit G5, G6 and G4 according to the sequence in the operating unit calling sequence, wherein, preferentially unit G5 is adjusted to and completely send out state and make its output power promote 0.5MW; Again the output power of unit G6 is promoted to 0.3MW subsequently; Last again by the output power of unit G4 lifting 0.4MW, output power wind energy turbine set is total with this is promoted to 13MW by 7.3MW, thereby meets the power demand of electrical network.
The above be take the situation of two kinds of power per liter and is had been described in detail as the blower fan call method of example to wind energy turbine set provided by the invention.In actual applications; meet the grid power demand if need wind energy turbine set to fall power; preferentially make to fall power at operating unit in the operating unit calling sequence, and in the time all after power falls in operating unit, still can not meeting the grid power demand, then make at operating unit, to shut down accordingly.Power falls in the situation that this, can be according to actual conditions using this continuous working period or accumulated running time as the sequence parameter, and preferentially call and unit that the adjust operation time is long.
It will also be appreciated that, previous embodiment is based on determines the sequence parameter working time (for example this continuous working period and/or accumulated running time), yet the present invention is not limited thereto, but also can adopt the status parameters such as temperature of critical components such as generator, vane change device and/or the current transformer parameter that sorts.In this case, can adopt separately the temperature T 2 of temperature T 1, vane change device of generator and current transformer temperature T 3 one of them determine the sequence parameter, and the parameter that will sort is set as this status parameter itself, also can adopt the temperature T 1 of generator, two or more status parameters in the temperature T 2 of vane change device and the temperature T 3 of current transformer are determined the sequence parameter, for each status parameter, assign weight simultaneously, and calculate the sequence parameter based on this, for example, adopt the temperature T 1 of generator simultaneously, the temperature T 2 of vane change device and the temperature T of current transformer 3 are determined the sequence parameter, and to be respectively that these three status parameters assign weight be 50%, 40% and 10%, this sequence parameter is 50%T1+40%T2+10%T3 like this, then determine the blower fan calling sequence according to the sequence parameter calculated so again.
Further, in actual applications, also can be simultaneously based on working time (such as this continuous working period and/or accumulated running time) and critical component the status parameters such as temperature determine the parameter that sorts, and for each status parameter assigns weight, then based on mathematical model, calculate the sequence parameter, and determine the blower fan calling sequence with this parameter that sorts.Afterwards, when the wind energy turbine set power per liter, preferentially call the smaller unit of numerical value of sequence parameter; When power falls in wind energy turbine set, preferentially call the larger unit of numeric ratio of sequence parameter.
As another technological scheme, the present invention also provides a kind of blower fan calling system of wind energy turbine set.Blower fan calling system specific embodiment of the present invention provided below in conjunction with Fig. 2 is described in detail.

Calling sequence determining unit 220 is determined the sequence parameter according to this status parameter, and based on the sequence parameter, the blower fan in wind energy turbine set is sorted to determine the blower fan calling sequence.Wherein, the blower fan calling sequence can comprise operating unit calling sequence and standby unit calling sequence.So-called operating unit calling sequence refer to by wind energy turbine set all at the unit of operation according to the numerical values recited of the parameter that the sorts resulting unit calling sequence that sorted; So-called standby unit calling sequence refer to by wind energy turbine set all the standby units according to the numerical values recited of the sequence parameter resulting unit calling sequence that sorted.
