System and method for operating a steam turbine with digital computer control having improved automatic startup control features

摘要

A steam turbine operates with a control system having a programmed digital computer for automatically controlling steam flow to satisfy turbine speed or load demand during turbine startup, synchronization and load operation. Steam flow is controlled throughout the entire startup sequence by means of speed control signals determined by the computer as a function of monitored turbine operating conditions. While under load operation the turbine is under digital computer load control, and operational parameters are monitored by the digital computer.
