Abstract: Disclosed is a reactance-injecting module used to balance the currents among the phases of polyphase electric power transmission lines or to manage power flow among alternate paths, where the reactance-injecting module has high-speed, dedicated communication links to enable the immediate removal of injected reactance from all phases of a phase balancing cluster when a fault is detected on any one of the multiple phases. The reactance-injecting module may communicate information on a detected fault to the other reactance-injecting modules of the phase balancing cluster within 10 microseconds after the fault is detected to allow the phase balancing cluster to eliminate injected reactance from all phases within 1 millisecond after the fault is detected. This provides extremely fast neutralization of injected reactance to minimize interference with fault localization analyses.

Abstract: Disclosed is a reactance-injecting module and its method of use to balance the currents among the phases of polyphase electric power transmission lines or to manage power flow among alternate paths, where the reactance-injecting module has high-speed, dedicated communication links to enable the immediate removal or reduction of injected reactance from all phases of a phase balancing cluster when a fault is detected on any one of the multiple phases. The reactance-injecting module may communicate information on a detected fault to the other reactance-injecting modules of the phase balancing cluster within 10 microseconds after the fault is detected to allow the phase balancing cluster to eliminate injected reactance from all phases within a time that is short compared to a cycle of the alternating current, such as 1 millisecond after the fault is detected. This provides extremely fast neutralization of injected reactance to minimize interference with fault localization analyses.

IPC: H02J3/00
CPC classification number: H02J3/0012
Abstract: A power flow control system is disclosed. The system includes impedance injection modules (IIMs) distributed along and connected in series to one or more power transmission lines. The system further includes dual-ring fiber optic networks, with each dual-ring fiber optic network including a pair of fiber rings that provide data flow in opposite directions. The system further includes redundant power line coordinators in communication with the IIMs through the dual-ring fiber optic networks.

Abstract: In an impedance injection module in which multiple converter units are placed in series to realize a high level of impedance injection, switches, preferably vacuum interrupters, are connected to short the input and the output terminals of each individual unit. Unlike the fault-protecting switch across the entire module, these switches at the individual converter unit level serve several purposes, overload and surge protection of a unit, insertion loss minimization of an idle unit when the required impedance injection is small, and electrically removing a defective injection unit from the power flow to increase the overall reliability of the impedance injection module in the face of the failure of one unit or a few units. For more rapid response, particularly in response to faults, the vacuum interrupter at the unit level may be accompanied by an SCR switch in parallel with it.

Abstract: Systems and methods for controlling power distribution in a power distribution system are disclosed. The system comprises a first group of impedance injection nodes that includes two or more impedance injection nodes. Each of the impedance injection nodes of the first group is attached to a respective powerline of the power distribution system, and is configured to: respectively receive messages from other impedance injection nodes in the first group sent at different respective time slots, where each of the received messages includes node information of at least one of the other nodes, and broadcast a message to the other nodes in the first group at a time slot that is different from the respective time slots of the other nodes, where the broadcasted message includes node information of the impedance injection node, or node information of the at least one of the other nodes, or both.
