Extraction Turbines The 505E control can be configured to operate single automatic extraction turbines by controlling the interaction of the governor (HP or high pressure) valve and the extraction (LP or low pressure) valve. (The 505E can also operate the governor valve and the first extraction valve of multiple extraction turbines). Single automatic extraction 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 be extracted. The LP valve controls the entry of steam into the LP turbine stage, and the diverting of steam through the extraction line. 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 pressure/flow at constant levels. Changing the position of either the HP valve or the LP valve affects both turbine speed/load and extraction. If either the load on the turbine or the extraction demand changes, both the HP valve position and the LP valve position must be changed to maintain speed/load and extraction. 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.
The 505E control can be configured to operate single automatic admission turbines by controlling the interaction of the governor (HP or high pressure) valve and the extraction (LP or low pressure) valve. Single automatic 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 1-3) and at the downstream end of the HP turbine stage, before the LP valve. The LP valve controls the entry of steam into the LP turbine stage and through the admission line. As the LP valve is opened, more steam enters the LP stage. In most cases, the operator of an admission turbine needs to maintain both turbine speed/ load and admission pressure/flow at constant levels. Changing the position of either the HP valve or the LP valve affects both turbine speed/load and admission. If either the load on the turbine or the admission demand changes, both the HP valve position and the LP valve position must be changed to maintain speed/load and 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.
