Detailed description of the invention
With embodiment, the present invention is described in detail below in conjunction with the accompanying drawings.
Nuclear plant digital system provided by the present invention realizes the method for no-harass switch between each pattern of regulation valve
Mainly include following content:
Regulation valve optimization method from closed loop mode no-harass switch to open loop mode；
Regulation valve optimization method from open loop mode no-harass switch to closed loop mode；
The method that a number of plies value is followed the tracks of in DCS system two layers display.
Below each method is specifically described.
1. closed loop mode incision ring mode:
(1) former method: as it is shown in figure 1, former actuator regulation control in, the manual aperture input value under open loop mode without
The output valve of the automatic tracking regulator of method.When closed loop mode is cut to open loop mode, owing to being manually entered value with actuator during switching
Output valve inconsistent, it is possible that disturbing phenomenon.
(2) optimization method of the present invention: in order to reach the purpose of no-harass switch, the outlet side at actuator adds
One CALCA functional module, refers to Fig. 2.
From figure 2 it can be seen that RI01 (actuator output) and RI02 (input of operator under manual mode) delivers to
In this CALCA functional module.When setting value pattern switches to manual output mode, RO01 (output of functional device) is equal to always
RI01 (actuator output), so the control signal of valve is not changed in, only one layer when DCS system detects that RI02 is manual
Under pattern, the input signal of operator there occurs change, when i.e. operator have input new manual aperture input value, and this functional device
Output become RI02 from RI01, whole process achieves no-harass switch.Some are patrolled simply to need configuration in this CALCA functional device
Collect and judge to select function, can independently realize the most completely.Separately it should be noted that due to this
The no-harass switch of scheme is to complete a layer of DCS system, does not has any amendment to two layers.
2. open loop mode cuts closed loop mode:
(1) former method: as it is shown on figure 3, in the control of former actuator, although former functional diagram is drawn by BCALCI/BCALCO
Foot achieves following function.But owing to manually output (sets outside DCS system two layers under manual output mode when being cut to closed loop mode
Value can not be modified due to un-activation), outer setting value only after manual mode is cut to closed loop mode operator just can enter
Row is manually entered amendment and is adjusted controlling, and so will result in pattern switching moment, and actuator is first adjusted to former setting value
Joint, regulates to desired value again after operator inputs desired value, may there is disturbing phenomenon.
(2) optimization method of the present invention: in order to reach no-harass switch, adds a CALCA merit at actuator input side
Can module, refer to Fig. 4:
The function that this functional device completes is in an open loop mode, outer setting value RSP tracking measurement value RI02, setting of actuator
Definite value be simultaneously sent to DCS system two layers show.It is so equal due to setting value and measured value, when from open loop mode
When being switched to closed loop mode, switching moment regulator theory can be held in place, operator can be manually entered target afterwards
Setting value, completes the no-harass switch of actuator.This CALCA functional device simply need some logical judgment of configuration select function,
Can independently realize the most completely.This scheme is also to complete, to two layers a layer of DCS system
There is no any amendment.
3. a number of plies value is followed the tracks of in two layers of display
(1) problem describes
Being switched to closed loop mode or time closed loop mode is switched on ring mode when regulation valve being carried out open loop mode, needing to exist
Carry out corresponding SETPOINT or OUTPUT setting operation on guidance panel, and this operation can realize in two ways.
A kind of is to directly input the value needing to set in corresponding guidance panel input frame, adopts and does not the most appoint
What problem, will not bring perturbed problem.
Another way is the most directly to input new value in guidance panel input frame, but by clicking directly on guidance panel
On increase and decrease button corresponding value is adjusted.And in two layers of corresponding regulation valve guidance panel, SETPOINT (setting value
The setting value of regulation) value of input frame and OUTPUT (manually the output of output regulation sets) input frame is in current handoff procedure
Do not have measured value and the output valve of actuator of real-time tracking actuator, but maintain last activation under this pattern
Numerical value.When using this kind of mode, due to two layers of analog value not having to follow the tracks of one layer, the value of two layers is also maintained at original value,
The most directly carry out increase and decrease adjust if be to increase and decrease based on two layers of original value, such one layer accept value be exactly with
The value of the increase and decrease on the basis of two layers of initial value, also it is possible to bring the disturbance even situation of over control.
(2) optimization method of the present invention
In order to avoid this situation occurs, the present invention proposes two layers of DCS system also can the value of real-time tracking actuator.I.e.
SETPOINT (setting value of setting value regulation) input frame and OUTPUT (the manually output setting value of output regulation) input frame exist
The analog value of the actuator of tracking can be shown as an analog quantity display module, so in regulation in the case of nonactivated
Device carries out open loop mode and is switched to closed loop mode or time closed loop mode is switched on ring mode, no matter what carries out on operation screen
Plant operational approach, can preferably complete no-harass switch.
Obviously, those skilled in the art can carry out various change and the modification essence without deviating from the present invention to the present invention
God and scope.So, if these amendments and modification to the present invention belong to the model of the claims in the present invention and equivalent technology thereof
Within enclosing, then the present invention is also intended to comprise these change and modification.
