Abstract :
The working regions of an adjustable-speed generation unit with a doubly fed machine connected to the power grid are determined. The analytical relations for the control range of the rotor voltage phasor due to the maximal permissible values of currents and voltages of the machine and supply cycloconverter are presented. Simulation results are shown to illustrate the operation of the system
