Embodiment
The present invention is that a kind of RB tests without trip method, and the variable parameter control of regulating system when RB occurs reaches the emergent compensation of incorgruous equipment in the same way, adheres to not switching to when the anti-overcurrent trip of surplus equipment and regulation quality are abominable manually.
Adopt when described RB occurs and become the pid parameter adjusting; Co-directional device strengthens and exerts oneself, and incorgruous equipment reduces exerts oneself, and the equipment maximum output is carried out amplitude limit to prevent its excess current, adheres to its automatic adjustment state when RB occurs, and no matter how regulation quality does not badly withdraw from auto state yet.
RB test of the present invention comprises without trip method:
1, the rapid reaction of regulating system.
Rapid reaction refers to that regulating system adopts two cover pid parameters, and a cover is used for regulating when unit normally moves, and is another set of for the adjusting under the unit RB state, and the reaction when normal of the adjusting under the RB state is fast, and effect is strong;
2, the emergent compensation of regulating system.
Emergent compensation refers to quick increase or the minimizing of exerting oneself to reaching in the same way incorgruous residue working equipment, take the pressure fan tripping operation as example, another pressure fan that do not trip is its co-directional device, two induced draft fans are its incorgruous equipment, if it all is 30% that RB tests the baffle opening of front two pressure fans, B blower fan tripping operation, then system becomes sum of the two 60% with the baffle opening of A blower fan rapidly, compensates the adjusting loss that the tripping operation of B blower fan causes with the emergency reaction of A blower fan.The simultaneously baffle opening instruction with induced draft fan reduces certain value, and to the 600MW unit, this value selection 6～8% is comparatively suitable.
3, the tolerance of the abominable degree of regulation quality.
If regulate parameter during the unit normal regulating badly to a certain degree, should remove automatic adjustment state, concurrent warning transfers operations staff's manual adjustments to, should tolerate the abominable quality of regulating parameter during RB, all the time adhere to system in automatic adjustment state, because fast more than the reaction of running person's manual adjustments of the reaction when automatically regulating.
4, prevent surplus equipment overload tripping operation.
Behind the unit trip, the rapid reaction of surplus equipment is easy to cause overcurrent trip, should limit the maximum output of surplus equipment, prevents its overcurrent trip, usually the baffle opening with surplus equipment is limited in about 80～85%, and occurrence should be groped when static debugging.
This engineering DCS regulating system adopts I/A ' the S scattered control system of Shanghai Fox's POLO company limited, and the larger regulating effect of scale parameter is more weak, and integral time is longer, and regulating effect is more weak.
Method 1: take pressure fan RB as example, the utilization of method 1 when pressure fan RB once is described.
Running person is pressing the manual stop button of B pressure fan on the spot, causes the tripping operation of B pressure fan, triggers unit RB action, utilizes method 1, adopts to become pid parameter control method, and regulate parameter before RB occurs and be: scale parameter P is 250, and integral parameter INT is 0.3 minute; RB adopts new adjusting parameter after occuring, and scale parameter P is 150, and integral parameter INT is 0.25 minute.No matter from scale parameter still from integral time, all strengthened the adjusting strength of system, make the response speed of system faster, the adjusting better adaptability when RB.
Method 2: take pressure fan RB as example, the utilization of method 2 when pressure fan RB once is described.
Running person is pressing the manual stop button of B pressure fan on the spot, causes the tripping operation of B pressure fan, triggers unit RB action, and before RB occured, two pressure fan baffle openings were 30%, two induced draft fan baffle opening and are 40%; The A pressure fan is forward device to the burner hearth air blast at this moment, and two induced draft fans of A, B are counter-directional device from the burner hearth air draught, and the effect of regulating system is the adverse effect of eliminating an air-supply tripping operation, keeps the relatively stable of furnace pressure.According to method 2, moment occurs in RB, and the instruction of A pressure fan baffle opening is increased to former two pressure fan baffle opening instruction sums 60% by original 30%; The baffle opening instruction of two induced draft fans respectively deducts 5% on original basis, become 35%, and participates on this basis separately the PID conciliation.The emergent compensation of system that Here it is, under proper parameter, it is faster that this compensation is reconciled speed than simple PID.
As shown in Figure 1, Fig. 1 is the recording curve that the tripping operation of B pressure fan triggers unit RB, and curve A O164102 is the baffle opening of residue co-directional device A pressure fan, as seen its should acutely open greatly when RB; Curve IDFAAO is the baffle opening curve of incorgruous device A induced draft fan, as seen its should acute aperture reduce when RB.
Method 3: as shown in Figure 2, the difference of setting value SP and regulated variable PV greater than tolerance value A after, illustrate that regulating system reconciles quality and worsen, when normal regulating, during non-RB, excise the regulating system automatic loop, change the manual adjustments by the running personnel.But this abominable regulation quality is frequent during unit RB, and manual adjustments can't satisfy the requirement of response speed under the RB operating mode, so will tolerate the generation of abominable regulation quality under the RB operating mode, setting value and regulated variable deviation greatly do not switch to manually yet;
Method 4: as shown in Figure 3, the unit tripping that RB triggers is to be tripped by the overload of surplus equipment to cause under many circumstances.Prevent unit RB emergency stop valve trip, just must limit the maximum output of unit surplus equipment, the maximum output of every equipment all is different, and this parameter need to be groped in static debugging.Take pressure fan RB as example, static state is found out when movable vane aperture A pressure fan 85% time and is reached its maximum output in this example, so as shown in Figure 3, the maximum baffle opening with pressure fan when RB occurs is limited in 85%.
