Adaptive automatic power capacitor controller for controlling a capacitor bank of a power distribution system |
摘要 |
A power capacitor controller that adaptively and/or automatically determines a variety of operational parameters, including adaptively and automatically establishing the line phase angle correction value; adaptively and automatically establishing the appropriate electrical levels determining connection and disconnection of the capacitor bank relative to the line; adaptively and automatically establishing appropriate guard voltage levels determining connection and disconnection of the capacitor bank relative to the line; automatically determining when the capacitor bank is inoperative; automatically determining when a reverse power line condition and a reverse current line condition exists; automatically determining when a capacitor bank switching operation is a result of multiple capacitor banks on the line, and automatically determining when the operational set points of the controller are reversed.
