5. a kind of coal fired thermal power plant gross coal consumption rate statistical analysis system, it is characterised in that for realizing as in Claims 1-4
Method described in any one, including：
Data acquisition device, for carrying out data acquisition to coal fired thermal power plant by DCS system；Wherein, the data of collection include
Generator outlet electricity ins and outs, station-service power consumption ins and outs, generator outlet active power and each coal pulverizer coal-supplying amount ins and outs；
Sentence module by mistake, for the data for collection, generator outlet electricity ins and outs sentence processing by mistake, by each coal pulverizer
Coal-supplying amount ins and outs sentence and handled by mistake；
Computing module, for by the data of collection calculate obtaining result of calculation；Wherein, result of calculation includes amounting to coal consumption
Amount, generator power output and standard coal consumption rate for generating；
Analysis module, for entering analysis to result of calculation, will not meet the rational data of actual production and carries out in result of calculation
Mark and show.
6. coal fired thermal power plant gross coal consumption rate statistical analysis system as claimed in claim 5, it is characterised in that described to sentence module by mistake
Including：
Electricity ins and outs judges unit by accident, and the calculation formula for calculating generator mean power P, P on duty is：Its
In, WNHanded over to the next shift ins and outs, W for generatorNUnit be 104KWh, WLSucceeded ins and outs, W for generatorLUnit be 104KWh, k are
Generator kilowatt-hour meter multiplying power, T is duty hour, and P unit is 10-1mW；Judge generator mean power P on duty whether in interval
In [0,330], if it is not, determining that the generator outlet electricity ins and outs of collection is wrong；
Coal amount ins and outs judges unit by accident, and for for every coal pulverizer, calculating, coal pulverizer is on duty averagely to give coal rate F；Wherein, F=(C2-
C1)/T, C2Handed over to the next shift ins and outs, C for coal pulverizer2Unit be t, C1Succeeded ins and outs, C for coal pulverizer1Unit be t, T for it is on duty when
Between, T unit is h, and F unit is t/h；Judge that coal pulverizer is on duty and averagely give coal rate to whether coal rate F is more than default maximum, if
It is, it is determined that the coal pulverizer coal-supplying amount ins and outs of collection is wrong.
7. coal fired thermal power plant gross coal consumption rate statistical analysis system as claimed in claim 6, it is characterised in that the erroneous judgement module
Also include：
Flow modular converter, if being data acquisition mistake for sentencing result by mistake, is transferred to manual entry data manipulation flow.
8. coal fired thermal power plant gross coal consumption rate statistical analysis system as claimed in claim 7, it is characterised in that the Coal-fired Thermal Power
Factory's gross coal consumption rate statistical analysis system also includes：
Memory module, for correct result of calculation to be deposited in into the webserver, and generates message by set form.
