IMPROVEMENTS IN OR RELATING TO ELECTRIC POWER PLANT SYSTEM AND METHOD FOR OPERATING A STEAM TURBINE ESPECIALLY OF THE NUCLEAR TUPE WITH ELECTRONIC REHEAT CONTROL OF A CYCLE STEAM REHEATER

摘要

An electronic system is provided for operating a nuclear electric power plant with electronic steam reheating control applied to the nuclear turbine system in response to low pressure turbine temperatures, and the control is adapted to operate in a plurality of different automatic control modes to control reheating steam flow and other steam conditions, each of such modes of control permitting turbine temperature variations within predetermined constraints and according to predetermined functions of time.
