SYNCHRONOUS INPUT CONTROL METHOD AND SYNCHRONOUS INPUT CONTROL DEVICE

Title:

SYNCHRONOUS INPUT CONTROL METHOD AND SYNCHRONOUS INPUT CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/154035

Kind Code:

A1

Abstract:

When switching the supply of power between a plurality of power supply sources, an input command is output to a breaker for switching when the frequency difference and phase difference between said power supply sources are respectively within a prescribed range. At least one of the power supply sources is a generator driven by a drive source via a transmission. A determination is made as to whether the frequency difference and phase difference between power supply sources are within a prescribed range. When the frequency difference and phase difference are within the prescribed range, the generator drive speed of the transmission is subjected to feedback control so that the frequency difference and phase difference are kept within the prescribed range. At this time, the generator speed command is computed by adding the output value obtained by proportional integrated control of the detected phase difference to the speed command for the transmission. The feedback control is performed on the basis of this generator speed command, and an input command is output to the breaker while the frequency difference and phase difference are in the prescribed range.
