With.;:;; It is about frequency beyond certain limits,: / - s / i; -1: 1the signal of the nonlinear block 2 .gs on the switch 4, then con: | 7 of the switch 4 is opened: :: en; the cervical block 6 is connected to pressure vopj 5. The latter is not suitable for the movement of the turbine valves. ii by the frequency regulator in block 3oim insensitivity of block 6. Thus when the frequency goes beyond the limits, the system provides: Automatic transition from pressure control mode to frequency control mode. The subject of a power supply system The boiler-turbine power unit control system with a constant rotational pressure frequency is connected, through non-linear blocks and a switch, to the turbine valve control unit, in order to automate the transition of the pressure control mode to the control mode frequencies, switch contacts are connected in parallel to the non-linear pressure regulator block, and the control input of the switch is connected to the output of the non-linear frequency control block.
