Abstract
The present invention provides a central current share coordinator for use with remotely and non-remotely controllable rectifiers coupled to an output bus. In one embodiment, the central current share coordinator includes a rectifier current resolver configured to determine an existing current share condition for the remotely and non-remotely controllable rectifiers. Additionally, the central current share coordinator also includes a load share adjuster coupled to the rectifier current resolver and configured to adjust an output current of the remotely controllable rectifiers toward a target current share distribution on the output bus.
Claims21
A central current share coordinator for use with remotely and non-remotely controllable rectifiers coupled to an output bus, comprising:
- a rectifier current resolver configured to determine an existing current share condition for said remotely and non-remotely controllable rectifiers;
- and
- a load share adjuster coupled to said rectifier current resolver and configured to adjust an output current of said remotely controllable rectifiers toward a target current share distribution on said output bus.
A method of current sharing for use with remotely and non-remotely controllable rectifiers coupled to an output bus, comprising:
- determining an existing current share condition for said remotely and non-remotely controllable rectifiers;
- and
- adjusting an output current of said remotely controllable rectifiers toward a target current share distribution on said output bus.
A battery plant, comprising:
- a battery string coupled to an output bus;
- remotely and non-remotely controllable rectifiers coupled to said output bus;
- a power system controller coupled to said remotely and non-remotely controllable rectifiers;
- and
- a central current share coordinator coupled to said power system controller, including:
- a rectifier current resolver that determines an existing current share condition for said remotely and non-remotely controllable rectifiers, and
- a load share adjuster, coupled to said rectifier current resolver, that adjusts an output current of said remotely controllable rectifiers toward a target current share distribution on said output bus.
