Patent number: 10261535Abstract: The subject specification comprises enhanced power system balance control for a multi-tier hierarchical electrical distribution network (EDN). The EDN comprises a specified number of distribution network node controller (DNNC) components employed to desirably control power system balance, data communications, and power distribution between respective tiers of the EDN to facilitate efficient power distribution. In each tier, a power system balance component (PSBC), associated with a DNNC component, can monitor power system balance, such as load phase balance, associated with multi-phase power distribution for its tier, and detect power system imbalances in that tier. A power balance correction action can be identified and executed (e.g., automatically) in response to the detected power system imbalance to rectify the imbalance, wherein the correction action can include dynamic switching of loads between phases and/or filtering of the power signal.Type: GrantFiled: March 2, 2016Date of Patent: April 16, 2019Assignee: General Electric Technology GmbHInventors: Ethan Clair Boardman, Subrahmanyam Saraswati Venkata
