Definitions
- the invention relates to a method and a device for power control on a power plant block consisting of a once-through steam generator, steam turbine and generator according to the preambles of claims 1 and 2.
- DE-C-942 514 describes such a control for steam engines, it has two control loops, namely a power control loop with the generator power output as a control variable and the primary energy supplied to the steam generator as a control variable, and a pressure control loop that measures the steam pressure upstream of the turbine or at the outlet of the steam generator at a predetermined setpoint by engaging in the steam throughput of the turbine via a control valve.
- a device for power control in particular the model simulation of the controlled system "steam generator” can be accomplished with relatively simple means.
- the power plant block consists of the once-through steam generator 1, the steam turbine 2 and the electric generator 3.
- the feed water supplied via line 4 is evaporated with the aid of the fuel or fuel-air mixture supplied via line 5 and supplied to the steam turbine 2 via the inlet valve 6 at pressure p 1 .
- the electrical power P e , i emitted by the generator 3 is compared in a comparison point 7 with a power set point P ei s set in the set point adjuster 8.
- the resulting control difference dP el is fed to a power controller 9 with PID behavior, the output variable of which acts as control signal YL on an actuator 10 engaging in the energy supply 5 and possibly on an actuator engaging in the feed water flow.
- the actuator YL of the power controller 9 is fed to the positive input of a differential element 11 and the input of a higher-order transmission element 12, in which the steam generation behavior of the “steam generator” controlled system is electrically simulated.
- the output signal of the transmission element 12 is connected to the negative input of the differential element 11, the output of which is connected to the input of a delay element 13 of the first order, which electrically simulates the storage behavior of the steam generator.
- the output of the delay element 13 carrying the pressure correction signal p k is connected to the negative input of a second differential element 14, to the positive input of which the pressure setpoint p s is connected.
- the reference variable dynamically corrected in this way is fed to a pressure regulator 15 with PI behavior; its controlled variable is the actual pressure value p, measured at a pressure measuring point 16 in the steam line to the steam turbine 2.
- the control signal y T of the pressure regulator 15 actuates the turbine inlet valve 6 and thus influences the steam throughput through the turbine.
- This pressure control loop is fast and uncritical, so that in connection with the power control loop, which is also fast and uncritical, there is a largely instantaneous response of the overall control of the power plant block to changes in the command or control variable "electrical power".
