Abstract
Means for better balancing and controlling of circuit loadings in electric power transmission networks to significantly reduce the number and/or cost of the transmission lines and facilities required to make a specific power transfer by significantly increasing the transmission capability of a given network by superimposing controlled circulating alternating currents for redistribution of power and current flows in the network.
Claims15
In an AC transmission network for supplying power, a power injection system for controlling current and power flow in separate portions of the network, said power injection system comprising:
- a source of AC power;
- a means to provide a DC source from said source of AC power;
- a means to provide a rapidly controlled AC source from said DC source;
- and
- a means to employ said controlled AC source at the most advantageous locations in the network to control the magnitude and distribution of AC current and power.
An AC electrical grid comprising:
- a power generating system;
- means connected to said power generating system to distribute AC power to a transmission network;
- at least one load station for using the power from said transmission network;
- and
- injection means in series connection with said transmission network, said means comprising a power injector transformer in at least one line controlling the current and power flow in that line and thereby controlling power flows in other lines of said transmission network.
A means to control AC transmission lines of a network comprising:
- a power injector transformer in series connection in a line;
- and
- a means to provide a controlled AC source controllable in magnitude and phase angle to said power injector transformer to control real power flow, reactive flow, and short-circuit currents in lines of said network, said means operable by a power rating of a small fraction of that flowing in the line.
