Changing the demand to the module will create an error between demand and feedback and the module will accordingly increase or decrease current to get a different position feedback and correct the error.

    Manual 26518V1 MicroNet TMR 5009FT Figure 4-2. Pump or Compressor Suction Pressure Control with Turbine Inlet Pressure Limiting and Dual Coil Actuator For this application a limiting type of control function was required to help preserve inlet header pressure in case of system header problems. Because the Auxiliary PID is the only controller that has this capability, it is used to sense turbine inlet pressure and limit governor valve position, based on a low inlet pressure setting.
  • Page 50 In order to limit generator load, the 5009 Control must be able to sense generator load. As shown in Figure 4-3 generator load is being sensed with a Woodward Real Power Sensor (RPS) and supplied to the 5009 Control’s KW droop input. Generator over-load protection is performed by a combination of the Speed PID and the speed setpoint maximum limit.

  • Page 51: Figure 4-3. Exhaust Pressure Control With Generator Power Limiting And Plant Import/Export Limiting

    With this RPS 12 mA represents zero power flow. Because of this feature, the RPS #8272-726 cannot be used with the 5009 Control to sense generator load/power. Please check with a Woodward certified distributor or factory for the correct RPS to use as a generator load sensor.
  • Page 52 Manual 26518V1 MicroNet TMR 5009FT This application uses a DSLC™ control for synchronization only.

When paralleled to the utility, turbine load varies based on the plant power demand.

Analogy: Accelerating into high speed lane with merging traffic. Derivative, sometimes called “preact” or “rate”, is very difficult to draw an accurate analogy to, because the action takes place only when the process changes and is directly related to the speed at which the process changes.

    Proportional effect. Integral Response Integral Gain as stated in the Woodward controls is repeats per minute (or Reset Rate). Therefore, a high amount of Integral gain (high number) would result in a large amount of Reset action. Conversely, a low Integral gain (low number) would result in a slower reset action.

The curves are relative since it depends on what type of control is desired in order to properly adjust Derivative time. For example, if minimum cycling is desired (as is shown here) then Derivative is added to the 1/4 decay cycle provided by Proportional until more than one cycle is removed and of course the 1/4 decay is destroyed.
