Title: Control system for variable speed transmission
Inventor: TANAKA HIROYUKI
IPC: H02P9/14
Filed: 1987-03-02
Abstract: PURPOSE:To increase the operating range of a variable speed transmission by constant current-controlling the excitation of a variable speed pumping-up power generator system. CONSTITUTION:An output from a measuring unit 7 is applied to a slip detector 6 to measure the rotating speed of a rotor 2. The detector 6 detects the slip frequency, and supplies its detected signal to a gate controller 4. The controller 4 generates a voltage responsive to the slip frequency through an automatic voltage regulator AVR on the basis of the voltage of a variable speed transmission terminal 8 to excite secondary exciting windings 21a-21d by a cycloconverter 5. Thus, even if it is operated at any rotating speed, an armature winding can always generate a voltage of system frequency.
