ABSTRACT:
A method for controlling a turbine-generator including: detecting a power-load unbalance between a turbine and a generator; measuring the duration of a power-load unbalance; measuring the rate of loss of an electrical load; and regulating steam flow through the turbine responsive to the rate of loss of an electrical load and the duration of the power-load unbalance; all of which results in more accurate and robust control of turbine-generator speed.
