To describe above each step below in detail.
Step s110: data input
Input master data and device data, and can carry out basic data processing.
Master data comprises meteorological temperature, area of heat-supply service and heating Thermal Synthetic index.Data processing can, for for example according to 0 DEG C of the highest temperature, the lowest temperature-10 DEG C, can generate mean temperature and be-5 DEG C automatically.Certainly, the invention is not restricted to this, also can obtain temperature on average by more temperature values.According to an embodiment, can accomplish that by large-scale cloud computing center every variation ± 0.5 of meteorological mean temperature DEG C adjusts heat supply dispatch command, arrange production, rationally energy-conservation.

Step s120: generate dispatch command
According to master data, can calculate the required hour thermic load of heating system and whole day thermic load.According to basic data and device data, can form the dispatch command in the scheduled time, such as firing rate dispatch command, boiler startup number of units dispatch command and the instruction of boiler operatiopn time scheduling etc., but technical scheme of the present disclosure is not limited to this.
Hour thermic load is calculated by following formula (1):
Q=Qmax(tn-t′w)/(tn-tw)(GJ/h) （1）
Qmax=q*A （2）
Wherein:
Tw be heating calculate minimum outdoor temperature (DEG C), for example area, Inner Mongol is-20 DEG C.
T ' w be outdoor temperature (DEG C).
Tn be indoor standard heating temperature (DEG C), be for example 18 DEG C.
Q(W/m
2) heating Thermal Synthetic index, as mentioned above, can be design heating index, historical heating index and actual heating index one of them.
A is Areas benefiting from central heating (m
2).
Q is hour thermic load (GJ/h) under tn, t ' w condition.
Qmax is heat supply network maximum heating load (GJ/h).
In addition, for simplicity, below provide some known unit conversions:
1Kwh=3600000J=3.6*10
6J；
1KJ=0.28wh
1GJ=1*10
9J=1*10
6KJ；
1 card=4.1868J;
1 kilocalorie=1000 card=4.1868KJ;
1GJ=238900Kcal
1GJ=277.78 degree (or Kwh)=277777.78wh
Operate to for the first time example with system at Heating Period below and carry out calculation specifications, wherein suppose that area of heat-supply service is 1,000,000 m
2, average design heating index is 55w/m
2, meteorological temperature is up to 0 DEG C and minimum for-10 DEG C, and mean temperature is-5 DEG C.
Generate firing rate dispatch command
One, given area of heat-supply service and average design heating index, calculate design heating load per hour
For example, be 1,000,000 m at area of heat-supply service
2time, calculate design heating load per hour: Qmax=1,000,000m
2* 55w/m
2* 1h=5.5*10
7wh=198.0GJ.Wherein, average design heating index is 55w/m
2.
Two, calculate the per hour thermic load of given area of heat-supply service under predetermined temperature on average
Qmax=198.0GJ, tn=18 DEG C, brings formula (1) into for t ' w=-5 DEG C
Q=Qmax(tn-t′w)/(tn-tw)
Can calculate the per hour thermic load of 1,000,000 square meters under DEG C meteorological condition of temperature-averaging-5:
=198.0GJ*【18-（-5）】/【18-（-20）】
=198.0GJ*23/38
=198.0GJ*0.61
=121GJ
Three, calculate whole day thermic load
Whole day thermic load is 121GJ*24=2904GJ.
After calculating whole day thermic load, can also, according to modes such as the mean temperature empirical datas of the every day of storing in database, obtain the whole day Load Distribution figure of unit interval section, as shown in Figure 3.
Four, calculate day firing rate and boiler operatiopn number of units
Based on fuel heating card number and boiler thermal output, can obtain a day firing rate.
Taking fire coal as example, suppose that coal-fired heating card number is 5000kcal/Kg, boiler thermal output is 83%, in the situation that whole day thermic load is 2904GJ, day coal consumption is for can be by calculating as follows:
2904GJ*238900Kcar/GJ=6.937*10
8Kcal
6.937*10
8Kcal/5000Kcal/Kg=139000Kg=139T
139T/83%=167.5T。
According to a hour thermic load, can calculate required boiler general power:
121*277777.78wh/1h=33.61Mw
Be equivalent to 0.7Mw according to the power of 1 ton of (t/h) steam boiler, and consider and boiler efficiency be scaled ton:
33.61/0.7/0.83=57.8 ton, closes 2,40 tons of boilers.
If 1 ton of boiler hour coal consumption is 0.133t/h, hour coal consumption of 40 tons of boilers is 40*0.133=5.32t/h, and the boiler total day operation time is 167.5/5.32=31.48h.2 40 tons of boilers can respectively move 15.74 hours.
Similarly, if adopt diesel oil as fuel, suppose that diesel oil heating card number is 10200GJ/Kg, a boiler hour consumption diesel oil amount is 0.032T/h, adopts above account form, can obtain:
Day boiler operatiopn time: 27.2h, every is moved 13.6 hours;
Day boiler operatiopn number of units: 29MW, 2;
Day is combustion diesel oil amount for boiler: 69.26T.
In like manner, if adopt combustion gas as fuel, suppose that combustion gas heating card number is 8598.9 kilocalories/M
3, a boiler hour consumption gas quantity is 0.038m
3/ h, adopts above account form, can obtain:
Day boiler operatiopn time: 27.2h, every is moved 13.6 hours;
Day boiler operatiopn number of units: 29MW, 2;
Day boiler gas quantity: 82.16m

For the building of known area of heat-supply service, according to average indoor temperature, and actual heating load in the scheduled time, can obtain the average actual heating index of unit of building according to formula (1) and (2).
Actual heating index can remain unchanged at whole Heating Period, also can be at whole Heating Period regularly or recalculate actual heating index according to actual conditions.
After obtaining actual heating index, select actual heating index as heating Thermal Synthetic achievement data, generate dispatch command.
For example, if detect that user's indoor temperature is 16 degree, generate the design heating index 55W/m that dispatch command adopts
2can not meet user indoor temperature and reach 18 DEG C, and actual heating index is 56.99W/m
2.Hence one can see that, and the actual heating index of corresponding building exceeds 1.99W/m than design heating index
2therefore, need to improve system heating load.Further, can be according to actual heating index, calculating heating load adjustment amount is 4.33GJ, this system need to be adjusted many heat supplies of instruction 4.33GJ.
For example, if detect that user's indoor temperature is 19 degree, generate the design heating index 55W/m that dispatch command adopts
2exceed user indoor temperature and reach 18 DEG C of required heating loads, and actual heating index is 54.07W/m
2.The actual heating index of corresponding building that hence one can see that is than the low 0.93W/m of design heating index
2therefore, need to reduce system heating load.Further, can be according to actual heating index, calculating heating load adjustment amount is 2.03GJ, this system need to be adjusted the few heat supply 2.03GJ of instruction.
