Feedforward (PDff), PID VARIABLE PARAMETER PID CONTROL etc..
Each major parameter is required for, during debugging, determining through substantial amounts of test.In DEB coordinated control system
In, the Control platform of system is affected bigger by drum heat storage coefficient.Heat storage coefficient arranges too small meeting and underestimates the accumulation of heat of boiler-steam dome
Ability, easily produces the toning of fuel quantity.If heat storage coefficient arranges relatively big, beyond the actual heat storage capacity of boiler, then lead
It is relatively slow that steam pressure can be restrained, and affects the regulation quality of main steam pressure.Therefore, in Directed Energy Balance Coordinated Control control system

Corresponding reduction；When ature of coal is poor, automatically the regulation effect of fuel master control PID regulator is strengthened, feeder command signal
Change will strengthen accordingly, accelerates the response of combustion control system.
The static load instruction feedforward of boiler oil is the boiler oil load generated with the unit Changing load-acceleration of twice
Instruction, the described load instruction needed for boiler master controller can be in advance by coal supply by the polygronal function of load with coal amount
Amount increases or is reduced to the coal-supplying amount needed for target load, reduces the pure of CFBB to a certain extent and delays
Time, improve the speed of response of boiler.
The dynamic load instruction feedforward of boiler oil is that after actual set load instruction deducts rate limit, actual set is born
The differential of lotus instruction, during by limiting the amplitude of the bound of differential and passing through different load amplitude of fluctuation correspondence difference differential
Between polygronal function determine the micro component that unit load instructs；The correction system of load dynamic Feedforward is determined by load change test
System, the micro component of load instruction is load instruction dynamic Feedforward with the product of differential correction factor.
The dynamic Feedforward of unit pressure is differential and the master that unit energy signal deducts unit energy signal after rate limit
Steam pressure setting value deducts the differential sum of main vapour pressure setting value after rate limit.Both can be come by load change test
Determine the correction factor of the bound of differential, derivative time and dynamic Feedforward.
Described bed temperature variation rate Vt to the dynamic Feedforward of boiler master be on the premise of meeting coal-air ratio according to bed temperature with
And the rate of change of bed temperature revise boiler master instruction.Bed temperature in the reasonable scope time, repaiied with fuel quantity by bed temperature variation rate
The fuel correction amount that positive function is corresponding, and according to correction factor corresponding to the deviation value of main vapour pressure, both products are boiler
Master control needs the fuel quantity revised；When bed temperature is beyond zone of reasonableness, boiler master instruction directly change 2 percent instruction, prevent
Bed temperature overtemperature.(main vapour pressure correction factor determines: Vt > 0.1 time, as pressure divergence △ P >-0.3, pressure correcting coefficient is 1, △
P <-0.5 pressure correcting coefficient is 0；During Vt<-0.1, as pressure divergence △ P>0.5, pressure correcting coefficient is 0, △ P<0.3 pressure
Correction factor is 1.) boiler master controller introduce bed temperature variation rate feedforward, due to the change of coal amount during varying duty
The change of bed temperature can be caused, without delayed due to main vapour pressure during this feedforward action, boiler master toning often occurs,
Cause coal amount too much and then cause the great fluctuation process excessively of main vapour pressure, introducing this feedforward and can make coal amount at bed temperature variable quantity very
Adjust back boiler master in time time big, make the change of boiler coal feeding amount in controlled range, it is achieved the stability contorting of main vapour pressure, enter
And realize set steady control.
The task of First air Boiler pressure control is to ensure that burning and the fluidisation wind of boiler.Primary air flow and secondary air flow pass through
Coal amount-primary air flow function, coal amount-total blast volume function form the instruction of respective air quantity, and total blast volume instruction takes with 30% minimum air quantity
Form final total blast volume instruction after big, according to boiler, primary air flow and secondary air flow illustrate that the ratio of 4:5 carries out proportioning.Boiler
Fuel command obtains the theoretical value of primary air flow through polygronal function and is multiplied by oxygen amount correction again and obtains the setting value of primary air flow.?
Adding load instruction in primary air flow command drcuit to feedover the sound state of primary air flow, load instruction is to First air air quantity
The feedforward of sound state is that the First air load instruction produced in order to the unit Changing load-acceleration of three times passes through that polygronal function is corresponding
The static of secondary air quantity feedovers, and the differential of unit load instruction refers to as primary air flow dynamic Feedforward, sound state primary air flow
Sum is made to be primary air flow instruction.The method can allow primary air flow move compared with unit load instruction and the advanced overshoot of coal-supplying amount
Make, make full use of the heat storage capacity of boiler, accelerate the response of boiler.Make main vapour pressure actual value energy fast under coordinated control mode
Speed follows the set-point of main vapour pressure.Owing to First air load instruction is more than boiler oil load instruction so that during lifting load
First air the most relatively coal-supplying amount changes in advance, and when can reduce varying duty to a certain extent, the fluctuation of bed temperature, not only increases machine
The speed of response of group, also improves the stability of boiler.
