Title:
SYNCHRONOUS START CONTROLLER FOR GENERATOR MOTOR
Document Type and Number:
Japanese Patent JP2014221006
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform smooth synchronous start by suppressing a level of oscillation generated at an electric current between power generators.SOLUTION: In synchronous start, a field circuit breaker 6A is turned on under a state where a mechanical brake 10A constrains rotation of a rotor 4A and supplies a field current Ifg to a field winding 5A. At this time, a preset signal from field current presetting means 18, because a change rate of a field current is limited by change rate limiting means 27, can suppress an oscillation level of an electric current I between generator motors running between a generator motor on start target side and itself immediately after a field circuit breaker 6A is turned on.
