The subject of the speed in order to group turbo - alternator

摘要

Device for regulating the speed in order to group turbo - alternator, characterized in that it comprises a first regulator (i) for the small movements intended to ensure an automatic control of power operation, this first regulator (i) being optimized in order to maintain the stability of the alternator about its permanent mode, whatever the configuration of the network in question, a second regulator (ii) for the large movements intended to work efficiently to disturbances, the more violent likely to occur, and a device (iv) detector of the variations of the signal of the electrical power for the switching of the first and second regulators (i, ii) in order to control by the first regulator or by the second, the degree of opening of the valves high pressure and low pressure of the turbine for driving the turbo - alternator.
