Title:
可変速発電電動機の運転制御方法及び運転制御装置
Document Type and Number:
Japanese Patent JP5207910
Kind Code:
B2
Abstract:
An excitation device supplies a three-phase AC excitation current to a variable speed generator-motor, and controls the variable speed generator-motor based on a three-phase AC excitation current command value obtained by vector-synthesizing, based on a slip phase from an exciting phase detector, a torque direction excitation current command value from a power adjustment computing device, and a magnetic flux direction excitation current command value from a voltage adjustment computing device by an excitation current adjustment computing device. The variable speed generator-motor includes a power fluctuation suppression circuit that causes the torque direction excitation current command value fixed to a value before switching to follow a torque direction excitation current command target value calculated from an effective power by a predetermined conversion circuit, filter circuit, and limiter circuit during a synchronous operation in an operation control method for operating to switch a variable speed operation method and a synchronous operation method.
