ELECTRONIC GOVERNING SYSTEM FOR TRIPLE PRESSURE STEAM TURBINE HA VING TMR ARCHITECTURE

摘要

An electronic governing system for triple pressure steam turbine having TMR architecture comprising of a plurality of control islands (EHTC TMR1, EHTC TMR2, EHTC TMR3), each such control island comprising of - Turbine Startup and Load Limiting Equipment (TSLLE), (3.20), - speed controller (3.03), - admission controller (3.09) - HP inlet pressure controller (3.12), - IP inlet pressure controller (3.14), - LP inlet pressure controller (3.16) and - HP exhaust temperature controller (3.18), characterized in that the said governing system ensures electronic governing of start up and shut down of turbine in a safe manner and synchronization of the generator without support of mechanical governors and in that the electronic governing system can continue to function without fault even in case of a single failure of either processor or module or channel or any field transmitter.
