Embodiment
For making those skilled in the art understand technological scheme of the present invention better, 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.
See also 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, gather the status parameter of each blower fan in the wind energy turbine set in real time.So-called status parameter comprise at least following parameter one of them: the temperature of Cumulative Elapsed Time, this continuous working period, 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, confirm the ordering parameter according to the aforesaid state parameter, and confirm the blower fan calling sequence based on this ordering parameter.Wherein, the blower fan calling sequence can comprise operation unit calling sequence and standby unit calling sequence.So-called operation unit calling sequence refer to in the 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 sorts; So-called standby unit calling sequence refer to in the wind energy turbine set all the standby units according to the numerical values recited of the ordering parameter resulting unit calling sequence that sorts.
Particularly, in step 120, when adopting a status parameter to confirm the ordering parameter, this ordering parameter is this status parameter itself.When adopting a plurality of status parameters to confirm to sort parameter,, and calculate the ordering parameter according to each status parameter and weight thereof for each status parameter assigns weight.Alternatively; When adopting a plurality of status parameters to confirm the ordering parameter; For each status parameter is provided with priority, the status parameter that priority is high is set at the ordering parameter, comes the corresponding blower fan in the wind energy turbine set is sorted based on this ordering parameter; That is, come the corresponding blower fan in the wind energy turbine set is sorted through the numerical value that compares the pairing ordering parameter of each blower fan.In this sequencer procedure; If the numerical value of the pairing ordering parameter of a plurality of blower fans equates; Then earlier said a plurality of blower fans are arranged side by side; And the corresponding blower fan in wind energy turbine set is reset to the status parameter that priority is hanged down a grade with the ordering parameter, and comes said a plurality of blower fans are further sorted with this after all sorting and finishing.By that analogy, with the complete blower fan calling sequence of final formation.
In step 130, call in the 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 satisfies the demand of electrical network, for example, make the output power of wind energy turbine set satisfy the power demand of electrical network.
Particularly, in step 130, need power per liter and standby unit calling sequence to exist under the situation of standby unit, call corresponding standby unit and adjust its running state based on standby unit calling sequence in wind energy turbine set; And after all calling, the standby unit in standby unit calling sequence still is not enough to the output power of wind energy turbine set is adjusted under the situation of target call; Further be invoked at the unit of operation and adjust its running state according to operation unit calling sequence, so that the working order of wind energy turbine set satisfies the demand of electrical network.Perhaps, need power per liter and standby unit calling sequence not to exist under the situation of standby unit, be invoked at the unit of operation and adjust its running state based on operation unit calling sequence, so that the working order of wind energy turbine set satisfies the demand of electrical network in wind energy turbine set.
And, in said step 130, need fall in wind energy turbine set under the situation of power, call corresponding unit and adjust its running state based on operation unit calling sequence; And after all calling, the unit in operation unit calling sequence still is not enough to the output power of wind energy turbine set is adjusted under the situation of target call; Further make the corresponding compressor emergency shutdown in this sequence based on this operation unit calling sequence again, so that the working order of wind energy turbine set satisfies the demand of electrical network.
Instantiation below in conjunction with the wind energy turbine set power adjustments comes the blower fan call method of wind energy turbine set provided by the invention is elaborated.In this example, the false wind electric field have 10 typhoon machine unit G1, G2 ..., G10, and the specified output power of completely sending out of every unit is 1.5MW, then 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 satisfying the power demand of electrical network, need constantly call the corresponding unit in the wind energy turbine set and constantly change its running state, for example; For satisfying the requirement of wind energy turbine set power per liter, need launch the standby unit or raise generated output at the operation unit; Perhaps, fall the requirement of power, need to stop using or reduce generated output at the operation unit for satisfying wind energy turbine set.
In order reasonably to call the corresponding blower fan in the wind energy turbine set, the first step needs the status parameter of interior each blower fan of collection wind energy turbine set in real time.In this example, know through the status parameter of gathering each blower fan in the wind energy turbine set: the current total output power of this wind energy turbine set is 7.3MW, wherein has 3 unit G1, G2 and G3 to be in rated power and completely sends out state; 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 the shutdown maintenance state.Below 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 this continuous working period (being designated hereinafter simply as this continuous working period) after launching.
Table one:
In second step, confirm the ordering parameter according to the status parameter that collects, and come the blower fan in the wind energy turbine set is sorted, to confirm the blower fan calling sequence based on this ordering parameter and ordering rule.Wherein, so-called ordering rule can be meant according to ascending still descending ordering of sorting of the numerical value of ordering parameter; So-called blower fan calling sequence can comprise operation unit calling sequence and standby unit calling sequence.
In this example; With this continuous working period as the ordering parameter; And come sorting and obtain the blower fan calling sequence at the operation unit in the wind energy turbine set according to this continuous working period ordering rule from short to long: promptly, operation 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 the standby unit calling sequence is zero, thereby these three standby units are arranged side by side.In fact; In practical application; When gathering the fan operation state; Can increase the status parameter of relevant standby time again, and with this parameter as the ordering parameter that produces standby unit calling sequence, then the standby unit in this wind energy turbine set is sorted and obtains standby unit calling sequence according to standby time ordering rule from long to short.
The 3rd step; Through relatively the power demand and the current gross output of wind energy turbine set of electrical network confirm whether wind energy turbine set needs lifting/lowering power; And call in the wind energy turbine set corresponding blower fan and adjust its running state according to power adjustment demand and above-mentioned blower fan calling sequence, so that the total output power of wind energy turbine set satisfies the power demand of electrical network.
Particularly; When electrical network needs power per liter; Generally speaking, preferentially launch the standby unit, and when launching the standby unit, preferentially launch the long unit of standby time; After launching, upgrade in time the states such as standby time of this unit are removed this unit and are recorded to operation unit calling sequence simultaneously from standby unit calling sequence.If there is not the standby unit that to launch in the standby unit calling sequence, then preferentially call in the operation unit calling sequence short unit working time.In order to describe clearlyer, divide two kinds of situation to come the power per liter process is elaborated below.
Situation one: only through calling the output power that 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.Through relatively finding out that 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 upwards promote 2.7MW with its gross output,, promotes 2.7MW through calling corresponding blower fan in the wind energy turbine set and adjusting its running state output power that wind energy turbine set is total that is.
Particularly, launch the standby unit in the standby unit calling sequence earlier, for example; Through each unit accumulated running time in the 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, simultaneously it is charged to operation unit calling sequence; Then; In current standby unit calling sequence, select and call the shortest unit of accumulated running time (being G7) once more; 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, simultaneously it is charged to operation unit calling sequence.Like this, only, can the output power that wind energy turbine set is total be promoted to 10MW, thereby make wind energy turbine set satisfy the power demand of electrical network by 7.3MW through calling G9 and G7 in the standby unit calling sequence.
Situation two: through calling the output power that standby unit and operation unit promote 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 13MW.Through relatively finding out that 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 upwards promote 5.7MW with its gross output,, promotes 5.7MW through calling corresponding blower fan in the wind energy turbine set and adjusting its running state output power that wind energy turbine set is total that is.
Particularly, call the standby unit in the standby unit calling sequence earlier, promptly; 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; Simultaneously it is charged to operation unit calling sequence, do not had the standby unit in the standby this moment unit calling sequence.After this, call again in the operation unit calling sequence at the operation unit, that is, call unit G5 and G4 successively according to the ordering in the operation unit calling sequence, 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 0.7MW subsequently.Like this, through calling G7, G8 and the G9 in the standby unit calling sequence and moving G5 and the G4 in the unit calling sequence, can the output power that wind energy turbine set is total be promoted to 13MW, thereby make wind energy turbine set satisfy the power demand of electrical network by 7.3MW.
Can find out through foregoing description, above-mentioned instance be with this continuous working period as the ordering parameter, and confirm the blower fan calling sequence based on this and carry out that blower fan calls.In practical application, adopt this mode can avoid causing the electric component temperature at its critical component place too high and cause fault because of the blower fan continuous working period is long.In other words, when adopting this continuous working period blower fan is sorted and when calling, can to reduce even avoid because of the too high fault that causes of electric component temperature as the ordering parameter and according to the length of working time.
It is understandable that, in practical application, also can accumulated running time sorted to blower fan and calls as the ordering parameter and according to the length of accumulated running time.When adopting accumulated running time blower fan is sorted and when calling, can to avoid unit the tired and initiating failure of equipment to occur because of accumulated running time is long as the ordering parameter and according to the length of accumulated running time.In other words, adopt accumulated running time to sort and when calling, can reduce even avoid fault tired because of equipment and that cause as the ordering parameter and according to the length of accumulated running time.
And when adopting accumulated running time as the ordering parameter, operation unit calling sequence is G5, G6, G4 in proper order.Like this,, can call unit G5, G6 and G4 successively, wherein, preferentially unit G5 is adjusted to and completely send out state and make its output power promote 0.5MW according to the ordering in the operation unit calling sequence for above-mentioned situation two; Again the output power of unit G6 is promoted 0.3MW subsequently; Last again with the output power lifting 0.4MW of unit G4, be promoted to 13MW with this output power that wind energy turbine set is total by 7.3MW, thereby satisfy the power demand of electrical network.
Being example with the situation of two kinds of power per liter above specifies the blower fan call method of wind energy turbine set provided by the invention.In practical application; Wind energy turbine set is fallen power and is satisfied the grid power demand if desired; Then preferentially make and fall power at the operation unit in the operation unit calling sequence, and in the time all after power falls in the operation unit, still can not satisfying the grid power demand, make again accordingly at the operation compressor emergency shutdown.Under this situation of falling power, can according to actual conditions with this continuous working period or accumulated running time as the ordering parameter, and preferentially call and adjust the unit of long operational time.
It will also be appreciated that; Previous embodiment is based on next definite ordering 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 status parameters such as temperature such as critical components such as generator, vane change device and/or the current transformers parameter that sorts.In this case, can adopt separately generator temperature T 1, vane change device temperature T 2 and current transformer temperature T 3 one of them confirm the ordering parameter, and the parameter that will sort is set at this status parameter itself; Also can adopt two or more status parameters in the temperature T 3 of temperature T 2 and current transformer of temperature T 1, vane change device of generator to confirm the ordering parameter; Assign weight for each status parameter simultaneously; And calculate the ordering parameter based on this; For example, adopt temperature T 2 and the temperature T 3 of current transformer of temperature T 1, the vane change device of generator to confirm the ordering parameters simultaneously, and to be respectively that these three status parameters assign weight be 50%, 40% and 10%; This ordering parameter is 50%T1+40%T2+10%T3 like this, then confirms the blower fan calling sequence according to the ordering parameter that calculates so again.
Further; In practical application; Also can be simultaneously based on working time (for example this continuous working period and/or accumulated running time) and critical component status parameters such as temperature confirm the parameter that sorts; And for each status parameter assigns weight, then calculate the ordering parameter, and confirm the blower fan calling sequence with this parameter that sorts based on mathematical model.Afterwards, when the wind energy turbine set power per liter, preferentially call the less unit of numeric ratio of ordering parameter; When power falls in wind energy turbine set, preferentially call the bigger unit of numeric ratio of ordering parameter.

Particularly, need power per liter and standby unit calling sequence to exist under the situation of standby unit in wind energy turbine set, fan condition regulation unit 230 calls corresponding standby unit and adjusts its running state based on standby unit calling sequence; And after all calling, the standby unit in standby unit calling sequence still is not enough to the output power of wind energy turbine set is adjusted under the situation of target call; Then further be invoked at the unit of operation and adjust its running state, so that the working order of wind energy turbine set satisfies the demand of electrical network according to operation unit calling sequence.Perhaps; Need power per liter and standby unit calling sequence not to exist under the situation of standby unit in wind energy turbine set; Fan condition regulation unit 230 is invoked at the unit of operation and adjusts its running state based on operation unit calling sequence, so that the working order of wind energy turbine set satisfies the demand of electrical network.
And, need fall in wind energy turbine set under the situation of power, fan condition regulation unit 230 calls corresponding unit and adjusts its running state based on operation unit calling sequence; And after all calling, the unit in operation unit calling sequence still is not enough to the output power of wind energy turbine set is adjusted under the situation of target call; Then further make the corresponding compressor emergency shutdown in this sequence, so that the working order of wind energy turbine set satisfies the demand of electrical network based on operation unit calling sequence.
