Abstract
There is disclosed a method and a control system for synchronizing the frequency of electrical current produced by a generator with the frequency of electrical current in an electric power grid so that the output of the generator can be provided to the grid. The generator is driven by an expansion turbine which utilizes hot pressurized gas from a process in which the pressure must be maintained constant.
