Embodiment 1
Static Simulation in this part, mainly comprises design conditions calculating and calculates with the stable state under the different off-design operating modes, as shown in Figure 4.Usage range: based on energy island system miniature and that small size gas turbine is formed, combustion acc power 0～1000KW can be to medium-sized and large scale system application facet expansion after the leakage of considering unit, inertia and performance change.Waste heat boiler: gamut from the hot-water type boiler to the vapor type boiler.Direct combustion machine: provide 10 degree following chilled water, and can expand fan coil or the like subordinate equipment.
Example 1: under the system design operating mode for Fig. 5, gas turbine 60KW generated output, efficient is 28%, configuration hot-water type waste heat boiler, design conditions cold water outlet temperature 90 degree, discharge 0.359 Kilograms Per Second, UTILIZATION OF VESIDUAL HEAT IN efficient is 71%.Then the part display result of static Simulation design conditions and off-design operating mode by be provided with or the result check can show any parts all parameters as shown in Figure 6 and Figure 7.Wherein, Fig. 7 is environment temperature is elevated to 300K from the 288K of design conditions systematic steady state output result.From figure as can be seen, when environment temperature raises, fuel engine power generation power will descend to some extent, and still, the waste heat amount that waste heat boiler obtains will increase, thereby make refrigerating capacity to rise.But the efficient of system will descend generally.
Dynamic simulation is mainly concerned with in the dynamic simulation and decides rotary speed system and variable speed system two big classes, and the variable speed system will provide concerning according to becoming of rotating speed and load, sees Fig. 8 for details.And each type systematic can carry out following variable working condition Calculation of transient process simulation.Main transient process comprises: a load variations dynamic process---comprise step variation, removal of load transient process and the self-defined dynamic process of selecting or import arbitrary proportion.B fuel change---program provides the physical data storehouse of more than ten kind of miniature gas turbine gaseous fuel commonly used, and the user can directly obtain composition and the calorific value of different fuel by selecting, and sees Fig. 9; The c start-up course---in order to simulate the dynamic start-up course of different units, provide three kinds of typical Starting mode, and can import self-defined Starting mode by the user; The thermoelectric cold Comprehensive Control of d---the automatic control of combined supply system under conditions such as different load demand, the variation of different working condition, different-energy allocation proportion is provided, moves dynamic transition process automatically; The self-defined dynamic process of e---become dynamic changing processes such as relation when becoming relation and heating load when becoming relation, refrigerating capacity when providing power load, in order to simulate dynamic transition process arbitrarily by the user.
Example 2: load variations system dynamics transient process, as shown in figure 10, take back the miniature gas turbine system of heat, under full load operating mode situation, the dynamic changing process of the suddenly negative step 30% of load, Figure 11, Figure 12 show the dynamic process analog result of deciding revolution speed control system and variable speed control system respectively.Working condition: operating mode, full-load conditions---generated output 60KW; Efficient 28%; Fuel Consumption 4.2g/s.From simulation result as can be seen, dispose under the rational condition, no matter decide rotating speed or variable speed system, can both guarantee the little fluctuation of rotating speed after the load variations, and can control soon in the gas turbine rotary speed controlled variable.In output power, efficient and fuel quantity transient process, it is violent that the overshoot of variable speed and fluctuation situation are all decided rotary speed system, this mainly is owing in the new rotating speed forming process, fires machine system rotating speed and set rotating speed to form bigger deviation, due to feasible adjusting is excessive.The two stable back output power is identical, and Fuel Consumption and efficient are suitable substantially.
Example 3: fuel change dynamic transition process simulation, system at Figure 10, under the condition of operating at full capacity, suddenly fuel type changes or fuel value changes or fuel pressure changes, and calorific value is changed to the variable speed control system control of 31715KJ/Kg and response dynamics transient process as shown in figure 13 from 57300KJ/Kg.From figure as can be seen, when fuel value took place to bear step, beginning power changed to some extent, and rotating speed reduces, and revolution speed control system works, and fuel flow rate increases, and through reaching new stable state after the convergence oscillatory process: rotating speed is the design conditions rotating speed; Power and efficient are the design conditions value, but fuel flow rate increases, and the adjusting time of whole dynamic process is about 60s.
Example 4: start-up course emulation Starting mode one, Starting mode one are the most frequently used a kind of startup forms of gas turbine engine systems, and it starts relation curve as shown in figure 14.Its whole process is: at first, drive the rotation of axle system by starting engine and reach warming-up rotating speed 19200rpm, warming-up 20s begins to quicken then, begins to spray into fuel ignition after a while, rotating speed quickens with given pace, temperature in and rotation speed relation be by starting curve definitions, and control regulate fuel flow by temperature in, after reaching certain rotating speed, actuating motor is threaded off, and drives generator by turbine this moment and continues to accelerate to given load.This Starting mode had both been taken into account and has been unlikely to give birth to the turbine thermal mechanical strength problem that warm excessive velocities causes, and simultaneously, accelerated speed has guaranteed that also pneumatic plant can not enter surge region, was a kind of quick Starting mode that guarantees under the safety.For this routine miniature gas turbine system, as can be seen from Figure 15, whole full load start-up course approximately needs about 120s.
Example 5: the thermoelectric cold dynamic transition process that jointly controls, system as shown in figure 16: the combustion gas that turbine is discharged is not directly to enter regenerator, but divide three with one by the waste heat divider, give regenerator, waste heat boiler and direct combustion machine respectively, the allocation proportion of this example is set by the user and is set at 20% backheat, 40% refrigeration, 40% heats.Dynamic process is: from originally seeing Figure 17 without any direct combustion machine under the afterburning situation and waste heat boiler initial steady state operating mode, it is that 2.5Kg/s and 0.5Kg/s rising are 1.0Kg/s that flow raises from 1.5Kg/s respectively, set outlet temperature and be respectively 278K and 363K, at this moment, the generated energy of gas turbine raises 20%, this transient process such as Figure 18.From example figure as can be seen when design temperature that changes direct combustion machine and waste heat boiler and the inlet water flow, the refrigerating capacity and the heating load of total system have been equivalent to change, simultaneously, the generated output of gas turbine also correspondingly improves, this just makes electric load, refrigeration duty and the thermal load of total system adjust simultaneously, and the way of the afterburning amount that system will be by changing gas turbine fuel amount, waste heat boiler and direct combustion machine realizes the load set.As can be seen from Figure 18, approximately through the time of 40～80s, system reaches new steady operation point.Here, the retardation time of direct combustion machine and waste heat boiler, the value of giving was smaller owing to there is not measured data, and the user can provide corresponding lag time constant according to the system of reality, and so, will change transit time, but can not change whole control process.Operation and Control and Optimization, mainly providing the user that the Control Parameter Optimization of system is seen Figure 19, mainly comprise: start-up course optimization---the starting process, the start-up parameters optimization that provide start mode optimization to change different start mode optimization system change the parameter optimization of determining under the start mode; The rotating speed Control and Optimization---by changing the rotating speed control mode poor regulative mode, indifference regulative mode arranged, regulate the rotating speed control effect that dynamic process is optimized and investigated to parameter; The temperature in Control and Optimization---according to the turbine temperature characterisitic of reality, optimize the temperature control characteristic by changing controlled variable.
Example 6: the control of quality under the different rotating speeds controlled variable is relatively controlled integration time constant by changing rotating speed, and gas turbine rotary speed control of quality comparative result is seen Figure 20.Among the figure, when the adjusting deviation metric was taken as rpm, 210s place from top to bottom integration time constant was respectively: 1e-4s; 5e-4s; 1e-5s; 5e-5s; 1e-6s; 5e-6s; 1e-7s.As can see from Figure 20, integration time constant from little to the process of big variation, rotating speed control has been experienced one from dispersing-constant amplitude-convergence-constant amplitude-diverging oscillation process variation characteristics, this just explanation, the gas turbine controlled variable must provide suitable parameter value according to different unit characteristics, otherwise can not reach the purpose of rotating speed control.Be directed to the situation of this example, it is proper that integration time constant should be taken as the 1e-5s-1e-6s interval.And in this interval, controlled variable still has the problem of an optimization.Systematic analysis mainly comprises heat-economy analysis, analysis of Available Energy, economic evaluation analysis.
