Person skilled in the art more fully understands the technical solution in the embodiment of the present invention, and make the present invention above-mentioned purpose, feature and
Advantage can be more obvious and easy to understand, is described in further detail below in conjunction with the accompanying drawings to technical solution in the present invention:
As shown in Figure 1, being a kind of thermoelectricity load distribution method embodiment based on multifactor impact provided by the invention, packet
It includes:
S101:Calculate unit heat consumption curve function;It specifically includes:By the variable working condition theoretical calculation of heat supply extraction steam unit,
The structure of unit heat consumption value relation curve when obtaining unit difference main steam flow and different electric load and Load Distribution
And form, and then obtain unit heat consumption curve function.

Data establish the mathematical model of each equipment of unit, and the mathematical modulo of basic each equipment of thermodynamic cycle structures to form according to unit
Type forms complete unit data model.
Wherein, the magnanimity thermal history data, including:Main steam pressure, main steam temperature, reheater entrance pressure
Power, reheater inlet temperature, each exhaust point temperature, each steam extraction point pressure, each regenerator exit water temperature, inlet water temperature, hydrophobic temperature
Degree, each regenerator shell pressure, pipe lateral pressure, boiler final feed temperature, pressure etc. include under each typical condition of unit
(each typical condition includes unit correlation heating power under 50%, 60%, 70%, 80%, 90%, 100% rated load to thermodynamic data
Learn data), accurate mathematical model foundation is carried out to unit using these thermodynamic datas, model is fully considered in foundation
Nonlinear characteristic and dynamic characteristic.
Unit associated hot Mechanical Data is acquired first, i.e., each temperature, pressure, whole parameters of flow measuring point are based on vapour
Turbine flow passage component characteristic, surface-type Regenerator characteristics, oxygen-eliminating device characteristic, water supply pump characteristics scheduling theory knowledge, are distinguished by model
Knowledge method recognizes correlation performance parameters, establishes above equipment mathematical models;And by following each section models (grade group is through-flow portion
Divide, regenerator, feed pump) spliced according to the basic thermodynamic cycle structure of thermodynamic conditions, form complete steam turbine heating power
EQUILIBRIUM CALCULATION FOR PROCESS model.
Wherein, it is as follows to establish process for the mathematical model of each equipment of unit:
1, grade group model
Expansion process line is that a smooth curve can for large steam turbine in actual stage group
Complete machine is divided into grade group several different being considered as more bleedings, the smooth thermal expansion process of such steam turbine complete machine is bent
Line can be divided into many sections by grade group, and each section of graph then can approximatively regard straight line as.By verification, by single grade group
Thermal expansion graph make the calculated value of steam condition parameter at different levels in the grade group obtained after line processing and disclosure satisfy that engineering
Using required precision.
In steam turbine, when flow passage component structure size is all constant, grade group (arbitrary several steam flow approximately equals
Series-connected stage) forward and backward steam parameter has following relationship with its flow:
Temperature correction term in above formula, is approximately equal to 1 under normal circumstances, can not consider, and in some special cases
Except (such as initial temperature or reheat temperature change).To Condensing steam turine, if being discussed with grade group between steam extraction section, pressure
Very little more usual than P1/P2 can be ignored, therefore above formula has lower reduced form:
Wherein G=KP, as Fu Liugaier simplify formula.In thermodynamic system of steam tur, it will be assumed that every grade is not stayed
Gale formula values of factor K is constant.
Whether become with the size of load by grade flow area, stage can be divided into governing stage and non-regulated grade.To more
Level steam turbine, it refers to first acting grade of steam turbine, and flow area can change due to partial-air admission with load variations
Become, has the function that adjusting, therefore be referred to as governing stage.
In general, governing stage efficiency is lower than intermediate stage efficiency, why using the relatively low grade of this efficiency, be because
High pressure cylinder air inlet will consider variable working condition, and main steam flow is different under different load, and governing stage is needed to be adjusted, to ensure
The safety of the efficiency of entire thermodynamic system of steam tur and intermediate each level work and stability.
(1) governing stage efficiency is with the change of main steam flow and great changes will take place, should take governing stage in the calculation
Efficiency curve is fitted, to achieve the purpose that reduce error.
(2) it can be obtained in the comparison with other off-design behaviours, except winter heating period operating mode and minimum steam extraction operating mode
(in the case of there is extraction steam for factories and heating steam extraction) needs outside individually consideration, and rest working conditions tubine grade group stage efficiency can
It is considered as a definite value.
2, feed pump model
In thermodynamic system of steam tur, deaerator feed water pump is a critically important part, for by boiler recirculated water from
Oxygen-eliminating device saturation pressure is promoted to boiler feedwater pressure.
Relationship is known as below by feed pump physical characteristic:
Wherein:The volume flow that G- passes through the water of feed pump;
H- water supply pumps lift;
η-feed pump working efficiency;
The mass flow for the water that Gs- feed pumps flow through;
Hout- water supply pump discharge water enthalpies;
Hin- entrance of water-supplying pump water enthalpies;
3, regenerator model foundation
As shown in Fig. 2, for the basic model schematic diagram of surface-type Recuperative heat exchanger.
Its basic model to establish process as follows:
When giving a regenerator outlet temperature Tout, that is, there are following temperature and pressure dependence.
TBackheat=Tout+TUpper end is poor
By regenerator saturation state it is assumed that saturation pressure P backheats by regenerator at this temperature is calculated.
When known to P backheats, there is following relationship:
PBackheat=Ps×(1-Ks)
Wherein, KS is extraction line pressure drop coefficient.
Grade group steam extraction point pressure can be obtained by the average extraction line pressure drop coefficient operation being calculated, is utilized
Fu Liugaier, which simplifies formula G=KP, can obtain after the grade of this level-one flow before flow, with grade and subtract each other that this grade of steam extraction can be obtained
GS is measured, i.e.,:
Gs=K0P0-K1P1
Meanwhile the enthalpy and stage efficiency acquired using the temperature of main steam before grade and pressure can be in the hope of main steam after grade
Enthalpy, and the pressure of main steam has been obtained by steam extraction point pressure after grade, it can be in the hope of exhaust point temperature TS using Matlab programs.
Following balanced type can be obtained using the thermal balance relationship of main steam steam extraction heat release and boiler feedwater heat absorption:
Gs×Hs+GHigher level is hydrophobic×HHigher level is hydrophobic-GIt is hydrophobic×HIt is hydrophobic=G × (Hout-Hin)
Wherein Hs=f (Ps, Ts);
HHigher level is hydrophobic=f (PHigher level's backheat, THigher level is hydrophobic)
HIt is hydrophobic=f (PBackheat, TIt is hydrophobic)
GIt is hydrophobic=GHigher level is hydrophobic+Gs
Hout=f (PWater supply, Tout)
Hin=f (PWater supply, Tin)
In balanced type only there are two unknown parameter Tin and T it is hydrophobic, and the two parameters by surface-type regenerator lower end difference pass
Known to system:
TIt is hydrophobic=Tin+TLower end is poor
By iterative calculation, can in the hope of-must meet balanced type two parameters solution, to acquire regenerator entrance water
Temperature, concrete operations flow is referring to Fig. 3.
During establishing model, this concept of introducing grade control volume.Grade control volume refer to include certain primary heater,
And include the connected part boiler feedwater of this grade of heater or the control of condensate line, bleed steam pipework and part hydrophobic pipeline
