CONTROLLING CIRCUIT FOR POWER CONVERSION SYSTEM

摘要

PURPOSE:To contrive to effectively use power and to prevent the failure of a power conversion device by maintaining a generator terminal voltage at a set point in a system for linking a permanent-magnet generator to an electric power system via frequency converter. CONSTITUTION:A generator side control system is provided with a voltage regulator 30 and the ignition phase command of a power conversion device 2a is outputted by a firing-angle regulator 32 so that the terminal voltage of a generator 1 detected by a voltage detector 28 coincides with a voltage command value E*. Thus, the phase of the generator terminal voltage relative to an electro-motive force induced in the generator is operated and the phase and magnitude of a generator output current are regulated so that the generator terminal voltage is maintained at a set point.
