Synthesis program design and compilation instructions for phase-modulating pressurized water and control lifting machine

Abstract: The information on the design and preparation of the synthesis program of the phase-modulated pressurized water and the control lifting machine is provided by the excellent manufacturers of flowmeters and flowmeters. Synthesizing program design and compilation instructions for phase-modulating pressurized water and control lifting machine Program design General idea The control program adopts a block structure. Set the subroutine SBR0 to control the phase-modulating pressurized water system of the unit; the subroutine SBR1 controls the unit to make up to the runner room immediately without delay when the load is shed. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the design and compilation of the synthesis program of the phase-modulated pressurized water and the treatment of the lifting machine. Synthetic program design and compilation instructions for phase-modulating pressurized water and control lifting machine General idea of ​​program design The control program adopts a block structure. Set the subroutine SBR0 to control the phase-adjusted pressurized water system of the unit; when the subroutine SBR1 controls the load rejection of the unit, the appropriate amount of gas will be added to the runner chamber immediately without delay [08>. The main program OB1 calls the SBR0 and SBR1 subroutine blocks respectively to control the two different simultaneous events. The specific control process in the main program uses subprogram calling and load shedding and lifting PID algorithm to interrupt the program to build a block structure. During the operation of the hydro-generator unit, the main program of this small system only needs to continuously query the starting conditions of the two subprograms. , and according to the starting conditions, decide whether to call the phase-modulating pressurized water subroutine or the load shedding and lifting subroutine. The control algorithm uses the algorithm to control the air intake to the runner chamber after load rejection, so as to control the water level or pressure in the state space of the runner chamber. The ping-pong strategy is used for phase adjustment, and the PID algorithm is used when the load is dumped and the machine is lifted. , the output value of PID is used to control the opening size of the main air supply valve (electric regulating valve). control program·OB1·(Main program) LDSM0.0AI0.0//The guide vane is in the fully closed position AI0.2//The generator outlet circuit breaker is in the closed state SM0.0, 1//The unit phase modulation operation status flag is set to SQ0.0 , 3//Add working power to the main gas supply valve and electrode water level signal device; open the main gas supply valve. =Q0.3//Open the auxiliary air supply valve CALLSBR_0LDSM0.0AI0.1//The opening position of the guide vane is above no load ANI0.2//The circuit breaker has tripped SM0.1, 1//The unit load rejection has occurred sign Set SQ0.0, 2//Add working power to the main gas supply valve and open the main gas supply valve without delay immediately =V5000.0//Send the upper computer to start the unit accident shutdown command CALLSBR_1LDV5000.1OV5000.2RM0.0, 1 //The unit phase modulation operation status flag reset RQ0.1, 2//Close the main gas supply valve, DSX cut off the power = Q0.4//Close the auxiliary gas supply valve LDQ0.1TONT37, 50//Delay 5SLDT37RQ0.0, 1 //Remove the main air supply valve power supply.
