Description
Technical field
The invention belongs to integration of production and marketing operations field, it is energy-saving and cost-reducing instrument.
Background technology
The modernization that enterprise utilizes integration of production and marketing operations system help enterprise to realize management becomes trend now.By carrying out the transformation of orderly management to enterprises, enterprise can be helped to break department's wall, ensure interdepartmental information flow.Sales department, engineering department and Cheng Chan department supervise mutually, and avoid mutually the generation of " making a cart behind closed doors " situation, and real realizes the controlled integration of production and marketing operations of enterprises.The each productive unit production schedule wherein formulated according to the change release information of sales department is exactly a wherein important part.Present integration of production and marketing operations system is made up of master server, client, GPS positioning system, front server and each secondary factory middleware server.
Because integration of production and marketing operations system does not consider the impact of electric load fluctuation on energy consumption when the plan of arranging production and rhythm of production, therefore cause a large amount of electric power energy consumption and waste.Must solve existing integration of production and marketing operations system optimization.
Summary of the invention
The present invention seeks to integration of production and marketing operations system to improve, in the plan of arranging production with when regulating rhythm of production, utilize power fluctuation energy consumption model to reduce power fluctuation, thus reach the object reducing electric power energy consumption.
Technical scheme of the present invention:
Based on the shortcoming of integration of production and marketing operations system standard framework, must improve this framework, namely on body frame structure, set up energy conservation station and energy middleware server.
For ensureing independence, the stability of energy conserving system, in system, increase the energy conservation station of a built-in fluctuation energy consumption model, increase an energy middleware server simultaneously and integration of production and marketing operations system and energy centre system interface are formed energy-saving integration of production and marketing operations system architecture.Energy-saving integration of production and marketing operations system architecture is made up of master server, energy conservation station, energy middleware server, client, GPS positioning system, front server and each secondary factory middleware server.
Wave energy consumption model is entered because energy conservation station is built-in, operating personnel are when arranging production planning adjustment rhythm of production, first the short-term plan time that this planning adjustment rhythm of production causes (is generally 15 points by energy-saving workstation, 30 points, when 1, when 6) in undulating current in peak point current average with read from energy centre system corresponding point for the previous period in (being generally January or the N month or 1 year) average current carry out rule and appraise and decide, meet power conservation requirement (fluctuation energy consumption and basal energy expenditure are than being △ P/P<0.1%), then substantial manipulation can be carried out, if do not meet power conservation requirement, then prevention operation is carried out, thus reach energy-conservation object.
Reduce a method for energy consumption based on energy-saving integration of production and marketing operations system, comprising:
1, the parameter in the raw data recorded according to energy centre system draws electric current primary curve figure;
2, the average current value L1 of primary curve is calculated;
3, current peak curve is drawn: when the peak value in primary curve data is more than or equal to average current value, current peak is raw data peak value; When the peak value in primary curve data is less than average current value, current peak is by average current value value;
4, the average current value L2 of peak curve is calculated;
5, Δ I=Δ I peak=L2-L1 is calculated;
6, simple and easy mathematical model is set up:
【R(I+ΔI)2ΔT/2+(RI-ΔI)2ΔT/2】/RI2ΔT＝(I2+ΔI2)/I2
Fluctuation energy consumption and basal energy expenditure are than being △ P/P=(△ I/I) 2
(△ P/P>0.1% does not then meet power conservation requirement; △ P/P<0.1% then meets power conservation requirement)
I represents the electric current of electric power incoming line,
T represents the time,
Δ I represents the difference of peak to average and grand mean,
R represents electrical network resistance,
Curve 2 represents the average current value L2 of peak curve,
Curve 1 represents the average current value L1 of primary curve,
Formula can find out that the energy consumption of the curve 2 when undulating current Δ I is zero equals bent 1 fluctuation energy consumption is thus zero.
7, enterprise's fluctuation energy consumption model is set up:
Fluctuation energy consumption and basal energy expenditure are than being △ P/P=(△ I/I) 2;
ΔI＝ΔI1ψ1、ΔI2ψ2…ΔINψN；
I＝I1ψ1、I2ψ2…INψN；
(△ P/P>0.1% does not then meet power conservation requirement; △ P/P<0.1% then meets power conservation requirement; )
ψ 1, ψ 2 ... ψ N is the accounting that each bar electric power incoming line accounts for total amount;
Δ I1, Δ I2 ... Δ IN be each bar electric power incoming line short-term plan time (be generally 15 points, 30 points, 1 time, 6 time) current peak average be;
I1, I2 ... IN is the electric current average that each bar electric power incoming line (is generally January or the N month or 1 year) for the previous period;
If meet power conservation requirement, can operate; If discontented sufficient power conservation requirement, cannot operate.
Beneficial effect of the present invention: energy-saving integration of production and marketing operations system adds fluctuation energy consumption model, when arranging production planning adjustment rhythm of production, first carries out Evaluation on Energy Saving, has saved a large amount of electric energy, reduce energy consumption in practice.
Accompanying drawing explanation
Fig. 1 is Zhao Gang 1# line Modling model figure.
Embodiment
In system, increase the energy conservation station of a built-in fluctuation energy consumption model, increase an energy middleware server simultaneously and integration of production and marketing operations system and energy centre system interface are formed energy-saving integration of production and marketing operations system architecture, form energy-saving concentrator station framework.Energy conservation station built-in enter wave energy consumption model, based on energy-saving integration of production and marketing operations system reduce energy consumption to realize example as follows:
Embodiment: Zhao Gang 1# line, Zhao Gang 2# line, Hou Gang 1# line, Hou Gang 2# line occupy 80% of full Taiyuan Iron and Steel Co. outsourcing power supply as the only four times 220kV power circuits of Taiyuan Iron and Steel Co., other outsourcing circuits and self power generation electric system gather imperfection and electricity accounting is little, so primary study Zhao Gang 1# line, Zhao Gang 2# line, Hou Gang 1# line, Hou Gang 2# line.
Zhao Gang 1# line Modling model as shown in Figure 1
1, the parameter in the raw data recorded according to energy centre system draws electric current primary curve figure;
2, the average current value L1 (this case time selects a year) of primary curve is calculated;
3, draw peak curve, get raw data peak value wherein greatly than average current value in primary curve data, less of than average current value average current value value.
4, the average current value L2 of peak curve is calculated;
5, Δ I=Δ I peak=Δ I paddy=L2-L1 is calculated;
Zhao Gang 1# line current obtains from energy centre database, and within 1 year, have 8784 (366 days) individual current value by a number of getting per hour, cannot launch too greatly demonstration due to quantity can inquire about from annex.Obtain Zhao Gang 1# line: L1=350.232A, L2=291.899, Δ I=58.333A.
