Fig. 2 be difference stabilize certain power fluctuation of wind generation set in parameter micro-capacitance sensor stabilize Contrast on effect;
Fig. 3 stabilizes energy storage needed for parameter for difference and contrasts;
Fig. 4 is that micro-capacitance sensor distributed power source power fluctuation stabilizes method realization flow figure.
Embodiment
Below in conjunction with accompanying drawing, enforcement of the present invention is elaborated: the present embodiment is implemented under premised on technical solution of the present invention, give detailed execution mode, but protection scope of the present invention is not limited to following embodiment.
Fig. 1 is the RC circuit model figure of low-pass first order filter, and in figure, Ux is input voltage, and Uy is output voltage, and the differential equation of circuit is:
Make τ=RC, then above formula becomes:
τ ∂ u y ∂ t + u y = u x - - - ( 2 )
For the specific demand of distributed power source power fluctuation, change above-mentioned voltage signal into distributed electrical source power signal, P outfor stabilizing distributed power source power output in rear micro-capacitance sensor, P infor stabilizing the distributed power source power output of front micro-capacitance sensor, then the corresponding differential equation adopting energy storage device to stabilize distributed power source power fluctuation is: τ ∂ P out ∂ t + P out = P in - - - ( 3 )
By above formula discretization, if T cfor stabilizing control cycle, at t k=kT c(k=1,2,3 ...) time is carved with
τ P out ( k ) - P out ( k - 1 ) T c + P out ( k ) = P in ( k )
Conversion above formula has: P out ( k ) = τ τ + T C P out ( k - 1 ) + T C τ + T C P in ( k ) - - - ( 5 )
Definition for stabilizing coefficient, above formula becomes further:
P out(k)＝λP out(k-1)+(1-λ)P in(k)
（0<λ<1）（6）
Through above-mentioned alternative transforms, becoming comprising two formulas (5) stabilizing parameter the formula (6) only stabilizing parameter containing, therefore only needing to set as required different parameter lambda of stabilizing and just can reach difference and stabilize effect.Analysis mode (6) is known, stabilizes parameter larger, stabilizes filter effect better; Stabilize parameter lambda less, stabilize filter effect poorer, therefore during practical application, under the satisfiable prerequisite of the energy storage device in micro-capacitance sensor, stabilizing parameter can get maximum.Fig. 2 be difference when stabilizing parameter in micro-capacitance sensor certain distributed power source power fluctuation stabilize Contrast on effect.
Energy storage device output is stabilized power and is: Δp b1=P out(k)-P in(k)=λ (P out(k-1)-P in(k)) (7)
Δp b1>0 energy storage device sends power, Δp b1<0 energy storage device absorbed power, analysis mode (7) is known, energy storage device send or the power that absorbs to stabilize parameter and be directly proportional.Fig. 3 is difference corresponding required energy storage power contrast of certain distributed electrical source power in micro-capacitance sensor when stabilizing parameter.
Fig. 4 is that micro-capacitance sensor distributed power source power fluctuation stabilizes method realization flow figure.Parameter lambda initial value is stabilized according to micro-capacitance sensor current operating conditions is given, its principle is: if current the linking together with bulk power grid of micro-capacitance sensor is incorporated into the power networks, bulk power grid can relax the power fluctuation in micro-capacitance sensor in distributed power grid, then stabilize parameter lambda initial value given less, i.e. λ <0.4; If current the disconnection with bulk power grid of micro-capacitance sensor carries out islet operation, in micro-capacitance sensor, the power fluctuation of distributed power source is comparatively large to its stabilizing influence, then stabilize parameter lambda initial value given comparatively large, i.e. λ >0.4.
Calculate according to formula (7) and currently stabilize the power fluctuation that required energy storage provides under parameter lambda Δp b2with power fluctuation rate Δp br, fluctuation ratio calculates according to the following formula
P br &Delta; = P out ( k ) - P in ( k ) P in ( k ) = P b &Delta; P in ( k ) - - - ( 8 )
For different operational modes, set different power fluctuation limit values Δp bsetwith power fluctuation rate limit value Δp brset, judge whether to carry out stabilizing of distributed power source power fluctuation in micro-capacitance sensor with these two definite values, that is:
∣ ΔP b1∣< ΔP bset;
∣ ΔP br∣< ΔP brset。
Then judge whether energy storage device current state in current micro-capacitance sensor meets and stabilize wherein distributed power source power fluctuation, if met, then after energy storage device exports power demand, calculate under the producible full power condition of energy storage device, stabilize precision and whether meet set point P bsetif meet, directly export control command Δp b3; If do not met, to stabilizing parameter lambda correction.
Consider the operation characteristic of different energy storage device in micro-capacitance sensor and different running status, to the correction of stabilizing parameter lambda, adopt different correction speed, if energy storage device charge/discharge rates is than very fast, and capacity is less, then select to stabilize parameters revision speed very fast, if energy storage device charge/discharge rates is slow, but capacity is comparatively large, then select to stabilize parameters revision speed less.
Obtain revised stabilize parameter after, recalculate corresponding power fluctuation Δp b1with power fluctuation rate Δp br, constantly repeat said process until be met the power fluctuation limit value of setting Δp bset, power fluctuation rate limit value Δp brset, what finally also will judge whether satisfied setting stabilizes precision P bsetrequirement, judges according to the following formula,
P bss-∣ ΔP b1∣>P bset（9）
P bsf-∣ ΔP b1∣>P bset（10）
In formula, P bssfor the current Absorbable rod maximum power of energy storage device, P bsfsend maximum power for energy storage device is current, stabilize precision if met, just final output stabilizes power control instruction Δp b3, and upgrade energy storage device real-time status.
According to above-mentioned analysis, stabilize method based on the distributed power source power fluctuation of lowpass filtering theory to achieve the best of distributed power source power fluctuation under micro-capacitance sensor different running method and stabilize, improve the quality of power supply in micro-capacitance sensor, ensure the safe and stable operation of micro-capacitance sensor.
Below disclose the present invention with preferred embodiment, so it is not intended to limiting the invention, and all employings are equal to replacement or the technical scheme that obtains of equivalent transformation mode, all drop within protection scope of the present invention.
