Extraction and Admission Turbines The 505E control can be configured to operate single automatic extraction and admission turbines by controlling the interaction of the governor (HP or high pressure) valve and the extraction (LP or low pressure) valve. Single automatic extraction and admission turbines have a high pressure stage and a low pressure stage, each controlled by a valve. Steam enters the turbine through the HP valve (see Figure 1-2). At the downstream end of the HP turbine stage and before the LP valve, steam can either be extracted or admitted (inducted) into the LP turbine stage. The LP valve controls the entry of steam into the LP turbine stage. As the LP valve is opened, more steam enters the LP stage and less is extracted. In most cases, the operator of an extraction turbine needs to maintain both turbine speed/ load and extraction or admission pressure/flow at constant levels. Changing the position of either the HP valve or the LP valve affects both turbine speed/load and extraction or admission. If either the load on the turbine or the extraction / admission demand changes, both the HP valve position and the LP valve position must be changed to maintain speed/ load and extraction/ admission. The movement of both valves is automatically calculated by the 505E’s ratioing logic based on the turbine performance parameters to minimize valve/process interaction. Speed Control The speed control receives a turbine speed signal from one or two magnetic pickups or proximity probes. The speed PID (proportional, integral, derivative) control amplifier then compares this signal to the speed setpoint to generate an output signal to the ratio/ limiter (through a low signal select bus).
al 85018V1 505E Digital Governor Woodward 11 The speed control amplifier can also receive a programmable (optional) droop feedback signal to increase the stability of the turbine/governor system. This droop signal can be proportional to the controller’s output signal or to the system’s generator load (kW) signal. The speed control’s setpoint is adjustable with raise or lower commands through the keypad on the front of the control, remote contact inputs or Modbus. The setpoint can also be directly set by entering the new setpoint from the keypad, or through either Modbus communications link. In addition, a remote speed setpoint analog input can be programmed to remotely position the speed setpoint.
