Abstract
The power distribution control system of the present invention provides a distributed intelligence, data acquisition and control system which collects and analyzes large amounts of data representing power usage from a power distribution substation and remote control units spread throughout a power distribution network. The system also provides the capability of various control functions for the substation and remote locations such as capacitor banks and pole switches along a distribution line. The system provide communications capabilities between local devices and also with remote control units. The system provides real time monitoring of power usage and real time control of various functions in the power distribution network.
Claims15
A control network for a power distribution system having at least one distribution subsystem, said control network comprising:
- a plurality of control units distributed at control locations throughout the power distribution system, at least one of said plurality of control units comprising a substation data acquisition controller which monitors power equipment at a substation within the power distribution system, said data acquisition controller having an analog-to-digital converter which receives signals from A.C. waveforms for current and voltage within a power line of said power distribution system, a memory device and a central processing unit to control said data acquisition controller, said at least one control unit determining the voltage and current in said power line;
- and
- a microprocessor-based system controller comprising a central processing unit, a plurality of communications channels with an interface and a memory module, wherein one of said interface connects said system controller to said plurality of control units via a shared communications link.
A control network for a power distribution system having at least one distribution subsystem, said control network comprising:
- a plurality of control units distributed at control locations throughout the power distribution system, at least some of said plurality of control units comprising power equipment controllers which monitor power equipment within the power distribution system, said control units comprising a microprocessor based central processing unit, monitoring inputs, control outputs and a memory;
- and
- a system controller in communication with said plurality of control units to provide coordinated control of said power distribution system.
