Abstract

PURPOSE:To make it possible to prevent output-fluctuation at the time of switching a governor and perform optimal regulation of parameters of the governor for control by installing two governors for control and tracking on a control loop for controlling the rotational speed of a turbine. CONSTITUTION:In governors for a condensing extraction turbine, the operation of a desired set-point OMEGA* of rotational speed is performed by a rotational speed setter 2, the operation of a desired extraction pressure set-point P* is performed by an extraction pressure setter 3, and these obtained set-point values are input into a non-interference matrix circuit 36 through respective governors 39, 40, and 37. The two governors 39, 40 for control and tracking are installed on a speed control loop. In the case of automatic operation mode, the signals of an integral operation-enable signal generator 43 are input into the governor 39, where integral operation is performed, and the initial value of an integrator of the governor 40 follows the output of the governor 39. In this state, even if making a changeover to manual operation mode, the input of a servo-amplifier 28 would not change abruptly.

When describing an electric turbine governor having an automatic operation mode and a manual operation mode, for example, for an extraction condensation turbine, both the rotational speed and the extraction pressure (flow rate) must not change when the operation mode is switched. Therefore, in the manual operation mode, the valve drive signal on the automatic operation mode side is made to match the valve drive signal on the manual operation mode side, and there are setting signals and feedback signals for the rotation speed and extraction pressure (flow t;:). It is necessary to change the setting (No. a) to maintain the relationship. Conversely, in automatic operation mode, it is necessary to match the valve drive signal on the manual operation mode side to the valve drive signal on the automatic operation mode side. This kind of operation is called tracking.

In automatic operation mode, each (switch switch 5゜7, 9
, 11, J, and 3 are all APC11i11 contacts, and are push buttons (W shown in the figure) of the rotation speed setting device 2.
i: According to the counter control number 46- generated by the operation, the Norse pulse from the /P pulse generator 16 is
The count result is converted into an analog signal by the A/D converter 24, and the target value Ω of the rotation speed is calculated.
Output as 7. Similarly, the target value of the bleed pressure can be obtained by operating the bleed pressure setting device 3. In automatic operation mode, the rotation speed and extraction pressure are each set to the target value Ω1. The speed regulating valve lift X1 (and the pressure regulating valve lift XL are automatically changed so that P* is reached. At this time, the manual operation side tracks the servo amplifier output so that it becomes the same as the automatic operation side. In other words, The outputs of the servo amplifier 28 on the automatic operation side and the servo amplifier 27 on the manual operation side are monitored by a deviation monitor 3), and a counter control signal is generated based on the magnitude relationship of the output signals, and a changeover switch 5, counter 19, and D/A converter are used. With 23 routes,
The governor valve lift target value XH in the manual tJJJ operation mode is changed so that the outputs of the servo amplifiers 27 and 28 are made the same. Similarly, the pressure regulating valve lift target value X in the manual operation mode is changed so that the output of the servo amplifier 29 on the automatic operation side and the output of the servo amplifier 3o on the manual operation side match. Even if you switch from automatic operation mode to manual operation mode in this state, the signals to the electro-hydraulic converters 33 and 34 will not change, so neither the speed control valve nor the pressure control valve will move, which will affect the speed Ω and pressure P. There isn't.

In manual operation mode, each selector switch 5゜7.9,1
1, 12.13i1: All MPC (lll) contacts, governor valve lift target value X1- in manual operation mode determined by push button (not shown) operation of governor valve lift setting device 1
The pressure regulating valve lift XH is controlled so that the pressure regulating valve lift becomes the target value XL of the manual operation mode *' which is determined by operating the push button (not shown) of the pressure regulating valve lift setting device 4. Lift XL is controlled. At this time, in the automatic operation mode f, 11, the servo amplifier output is tracked so that the servo amplifier output on the operation mode side of f11 is the same as the amplifier output. That is,
The outputs of the servo amplifier 29 and the servo amplifier 30 are monitored by the deviation monitor 32, and the counter control (iZ signal is generated, the selector switch 12, the counter 2
), the target value Pf of the extraction pressure is generated in the path of the D/A converter 25, and finally matches the outputs of the servo amplifiers 29 and 30 via the regulator 37 and the non-interference control matrix circuit 36. . In addition, the outputs of the servo amplifier 27 and the servo amplifier 28 are monitored by the deviation monitor 3, and a p counter control signal is generated depending on the magnitude relationship of the output signals, A target value Ω of rotational speed is generated, and is finally sent to servo amplifiers 27 and 28 via a regulator 38 and a non-interference matrix circuit 36.
Match the output of . At this time, if the target value Ω of the rotation speed and the actual rotation speed Ω do not match, the output of the servo amplifiers 2g and t9 changes due to the integral operation of the regulator 38, so that when tracking is completed, the servo amplifiers 27 and 28L7
) The outputs of the servo amplifiers 29 and 30 are equal, and Ω and Ω are equal. In this tracking method in manual operation mode, the same regulator is used for both control and dragging, so if you adjust the regulator parameters optimally for the original control, the tracking may be too slow or the tracking may be the main focus. ■There was a drawback that control performance deteriorated if the parameters (of the controller) were adjusted individually.

First, the automatic driving mode will be explained. In Figure 2, selector switches 5, 7, 9, 11° 12. 13, 41, 4
2 and 44 are all contacts on the APC side. The output signal of the integral operation enable signal generator 43 is input to the regulator 39, so that the regulator 39 performs a normal integral operation. On the other hand, the regulator 40
Since the g-minute computation enable signal is not input to , no integral computation is performed and the initial value of the integrator follows the output signal of the regulator 39. Therefore, the driving mode can be changed from automatic to manual.
At the moment when the switch is switched, all the changeover switches become the MPC side contacts, so the regulator 40 enters the integration state. However, since the initial value of the integrator of the regulator 40 matches the output of the regulator 39, the changeover switch becomes the MPC side contact. The input of the amplifier 28 will not suddenly change at the moment of . The configurations and functions of other elements are the same as those explained with reference to FIG. 1, and therefore their explanations will be omitted.

Next, the manual operation mode will be explained. Changeover switch 5
.. 7, 9, 11, 12, 13, 41°, 42.44 are all MPC side contacts. Integral operation enable signal generator 4
Since the output signal of No. 3 is input to the regulator 40, the regulator performs a common integral calculation. On the other hand, since the integral calculation enable signal is not input to the regulator 39, no integral calculation is performed and the initial value of the integrator follows the output signal of the regulator 40. Therefore, at the moment when the operation mode is switched from manual to automatic, all the changeover switches become APC side contacts and the regulator 39 is in the integrating state. Since it matches the output,
Switching II! There is no sudden change in the input of the servo amplifier 28 during this period. At that time, the output of the servo amplifier 28 matches the output of the servo amplifier 27, so the turbine speed does not fluctuate at the moment of switching. The 1-m structure of the other elements and their functions are the same as those explained with reference to FIG. 1, so their explanations will be omitted.

According to the present invention, by providing two regulators f, one of them (e.g. -11" adjuster 39) can optimally adjust the parameter for control, and the other one (e.g. the adjustment The device 40) can optimally adjust the parameters for tracking. Also, the initial value of the integrator of the regulator that is not performing the integral action (idling side) is made to follow the output value of the regulator that is performing the integral action (actual operation side). Therefore, even if the actually operating 11' unit is switched due to switching of the operation mode, the output of the regulator will not change at that moment. Therefore, excellent effects such as efficient turbine control and smooth switching of operation modes can be achieved.
