US 8,803,570 B2 · Multiphase electrical power assignment at minimal loss

Abstract

In a multiphase electrical power assignment, a processor: receives instructions to connect a bi-directional power device to a multiphase premise power source; determines that the power device is to be coupled to a target phase's phase connection; confirms that the power device is not coupled to any phase connections; and couples the power device to the phase connection, where the power device's power signal is synchronized with the phase connection's power signal. When the power device is in a connected state, the processor: issues a command to place each phase connection switch in an open state; in response to confirming that the phase connection switches are in the open state, issues commands to the power device so that a power signal of the power device will be synchronized with the target phase; and closes the phase connection switch corresponding to the target phase.

Dependent claims

A method for balancing the amount of power flowing through phases of a multiphase premises power source, comprising:

(a) determining that there is an imbalance in an amount of power flowing through a first phase and a second phase of a plurality of phases of a multiphase premises power source;
and
(b) delivering a power signal to the first phase using a bi-directional power device, wherein an amount of power delivered in the power signal from the bi-directional power device is derived from the determined imbalance in the amount of power flowing through the first phase and the second phase.

A computer program product for balancing the amount of power flowing through phases of a multiphase premises power source, the computer program product comprising:

a non-transitory computer readable medium having computer readable program code embodied therewith, the computer readable program code configured to:
determine that there is an imbalance in the amount of power flowing through a first phase and a second phase of a plurality of phases of a multiphase premises power source;
and
delivering a power signal to the first phase using a bi-directional power device, wherein an amount of power delivered in the power signal of the bi-directional power device is derived from the determined imbalance in the amount of power flowing through the first phase and the second phase.
