Changing load by way of switching steam turbine pitch aperture is rapidly, and to be protected by way of changing boiler oil amount
The energy requirement for demonstrate,proving steam turbine is more slow.Most domestic power plant units use direct-firing medium-speed milling pulverization system, and boiler steams
Vapour generation delay time is larger, reaches between 2 minutes to 3 minutes mostly, and the old fired power generating unit time of some long services is longer,
Reach 5 minutes to 8 minutes, causes unit AGC load responding slow, Load Regulation precision is overproof.In this case, with traditional
AGC control strategy is extremely difficult to the AGC check requirements of scheduling, and will lead to unit main steam pressure and main steam temperature substantially
Fluctuation, influences unit safety operation.
During varying duty, due to the significant difference of dynamic characteristic between boiler and steam turbine generator, simply pass through tune
Steam turbine pitch aperture is saved to change load, will lead to the reversed variation of main steam pressure, unit load variation tendency slows down.Cause
This, in traditional coordinated control, in order to guarantee regulating effect, boiler master feedforward needs to carry out the overshoot control of coal amount, will go up and down
To the load coal amount in advance plus or minus.After unit throws upper AGC, AGC load instruction frequent movement is dispatched, is just had this
Design scheme will lead to the fluctuation up and down of coal amount, confluent, cause the more unstable of unit.
In Control System for Thermal Power Units, the command signal equal proportion of numerous controlled parameters follows fuel quantity command signal to become
Change, including coal-supplying amount, primary air flow, secondary air flow, direct current cooker feedwater flow, denitration spray ammonia flow etc..Fuel quantity instruction
Fluctuation will lead to boiler combustion fluctuation, in turn result in primary wind pressure, secondary wind pressure, oxygen amount, furnace pressure, superheat steam temperature,
A series of major parameters such as reheat steam temperature, dum boiler steam water-level or direct current cooker centrum's temperature, DS NOx Est concentration
Fluctuation, unit safety, economy, environmental protection operation are adversely affected, and these parameter fluctuations finally also will affect main steaming
The stability of steam pressure.When unit key parameter is unstable, generated output Con trolling index will necessarily also decline.Therefore it designs
Suitable generated output instructs feed forward control logic, is that unit quick response AGC is instructed and guaranteed self-operating parameter stability
Essential condition, such as application No. is: 201510133100.6, the generated output for disclosing a kind of fired power generating unit coordinated control system refers to
Feed forward control method is enabled, thermal power unit boiler accumulation of heat is rationally utilized, power regulation scheduling method has been effectively relieved, and (R dispatches mould
Formula) under improve AGC instruction the speed of response and reduce boiler oil amount fluctuation between contradiction.It can not only be instructed substantially in AGC
Steam pressure is stablized before guaranteeing steam turbine when unidirectional variation, and boiler can be avoided to fire when AGC instructs slightly frequently variation
Doses fluctuation only increases a low-pass filter, it is only necessary to debug filter inertia relative to conventional feed forward control program
This parameter of time, and this parameter is only related with boiler heat storage size, has a setting parameter explicit physical meaning, configuration,
The advantages that debugging process is simple and convenient, but the significant difference of dynamic characteristic is asked between its still unresolved boiler and steam turbine generator
Topic.

Total fuel quantity, which is superimposed to form fuel quantity instruction and control to main vapour pressure actual value, refers to boiler input energy with generation load
It enables trend match, completes the overall process of unit varying duty response.
Core of the invention part: the level-one temperature reducing regulation of the superheater the following steps are included:
S1:AGC load instruction and unit actual load will be conveyed to accumulation of heat feedforward after forming unit load deviation；
S2: accumulation of heat, which feedovers, is converted into the knots modification of level-one attemperation water flow according to unit load deviation, is converted into knots modification
Duration and die-away time, and form control instruction, control instruction is sent to the Water flow adjusting valve of level-one desuperheat.
S3: the Water flow adjusting valve of level-one attemperator is adjusted level-one attemperation water flow according to control instruction；

Level-one attemperation water flow changes the accumulation of heat of superheater metal and carrys out quick response load scheduling, and instructs rationally cooperation with boiler, holds
Main steam pressure fluctuation caused by changing because of steam turbine pitch.
The principle analysis of scheme in the prior art: existing fired power generating unit coordinated control system generated output instructs feedforward control
Logical construction are as follows: AGC command signal forms the practical hair of unit after amplitude of variation limiting element, rate of change limiting element
Electrical power command signal after unit actual generation power command signal is using an advanced Dynamic mode, forms generated output
Feedforward control output signal is instructed, but under R scheduling method, when AGC instruction frequently slightly variation, this feedforward is logically present
A significant disadvantage, i.e. differentiation element boiler oil amount will lead to the amplification of high-frequency signal there are big ups and downs,
Detailed analysis is as follows: since differential part output valve is related with actual generation power instruction rate of change in differentiation element, working as change
When change rate setting value is relatively high, even if AGC instruction slightly variation, it is very big but lasting that differential part can also export an amplitude
Time very short pulse, so cause the instruction of boiler oil amount also occur significantly, the pulse change of short time, especially work as AGC
When instructing frequently small size forward and reverse variation, the positive and negative pulse that feed forward control logic meeting output amplitude is very big, the duration is very short,
It causes fuel quantity instruction substantially to swing, seriously affects boiler combustion stability.
The basic principle proposed by the present invention for participating in coordinated control using superheater accumulation of heat is: during unit generation, pot
It include a large amount of energy storage in the superheater heat exchange pipeline of furnace side, boiler superheater system includes roof enclosure wall pipe, pendant superheater, low

Metal accumulation of heat in formula superheater pipeline, makes to change into main steam flow, and the variation of main steam flow cooperates steam turbine
The degree collaboration that tunes to open unit actual load is regulated and controled, the variation cooperation boiler combustion of main steam flow is adjusted by master
Steam pressure actual value is regulated and controled, so as to achieve the purpose that the short time changes the power of the assembling unit and main steam pressure.
After method of the present invention is carried out engineering processing, using in Mr. Yu power plant 340MW Subcritical Units, process
It is as follows: first respectively it is high, in and underload section carry out level-one spray water flux upset test, to obtain level-one spray water flux and machine
