Abstract

1433611 Automatic control systems WESTINGHOUSE ELECTRIC CORP 16 April 1973 [24 April 1972 25 April 1972 26 April 1972] 18237/73 Heading G3R Steam valves in an electric power generating plant are controlled by a position reference signal digitally derived in response selectively to any of the following control loops:-speed (by analogue or digital signals) impulse chamber steam pressure, or megawatt output, and the invention is concerned with "bumpless" transfer from one control loop to another by calculating and applying a new reference value such that after change over the control signal will have the same steady state value as it had before change over. Details of the calculations for various combinations of transfer are given.
