摘要
The power and speed control device for a turbo-generator set of the invention has a generator, a turbine, and a governing valve with a positioning control input, for regulating steam fed to the turbine. The device includes a turbine speed controller, a turbine power controller, a maximum selection circuit, a minimum selection circuit, a summing stage, and a device for supplying a constant reference value to the input of the summing stage. The controllers are connected to the maximum selection circuit and the speed controller is additionally connected to the summing stage. The summing stage is connected to the minimum selection circuit, the maximum selection circuit is connected to the minimum selection circuit, and the minimum selection circuit is fed to the positioning control input of the governing valve.
