Document Type and Number:
WIPO Patent Application WO/2022/230689
Kind Code:
A1
Abstract:
Provided is a highly reliable power system. The power system (100) comprises a synchronous phase modifier (11) that has: an armature winding (11a) electrically connected to a power grid (P1); and a field winding (11b) that functions as a magnetic excitation circuit. The power system is configured such that: power is supplied from the power grid (P1) to the field winding (11b) when the power grid (P1) is operating normally; and the source of power supply to the field winding (11b) is switched from the power grid (P1) to a power grid (P2) when the power grid (P1) has an error.
