Abstract
Configurable binary circuits for use in electrical power systems may include an input/output port, a binary input subsystem for receiving a binary input signal, a binary output subsystem for transmitting a binary output signal, and a switch subsystem for selecting one of the binary input subsystem or the binary output subsystem for operation. Intelligent electronic devices (IEDs) and associated methods may include one or more configurable binary circuits.
Claims20
A configurable binary circuit for use in an electrical power system, comprising:
- an input/output port to at least one of receive a binary signal input as an input port or transmit a binary signal output as an output port;
- a binary input subsystem for receiving the binary signal input via the input/output port operating as the input port;
- a binary output subsystem for transmitting the binary signal output via the input/output port operating as the output port;
- and
- a switch subsystem for selecting one of the binary input subsystem or the binary output subsystem for operation such that the configurable binary circuit operates as either a binary input circuit when the binary input subsystem is selected or a binary output circuit when the binary output subsystem is selected.
An intelligent electronic device (IED) of an electric power system, comprising:
- configurable binary circuits, each configurable binary circuit comprising:
- an input/output port to at least one of receive an input signal as an input port or transmit an output signal as an output port;
- a binary input subsystem for receiving the input signal via the input/output port operating as the input port;
- a binary output subsystem for transmitting the output signal via the input/output port operating as the output port;
- and
- a switch subsystem for selecting the binary input subsystem or the binary output subsystem for operation such that the configurable binary circuit operates as either a binary input circuit when the binary input subsystem is selected or a binary output circuit when the binary output subsystem is selected;
- and
- one or more controllers in communication with and for operating the binary input subsystem of each of the configurable binary circuits and the binary output subsystem of each of the configurable binary circuits.
A method of configuring a binary circuit of an intelligent electronic device (IED), the method comprising:
- selecting a first configurable binary circuit to operate as a binary input circuit for receiving an input signal via an input/output port operating as an input port;
- selecting a second configurable binary circuit to operate as a binary output circuit for transmitting an output signal via another input/output port operating as an output port;
- receiving the input signal with the first configurable binary circuit;
- and
- transmitting the output signal with the second configurable binary circuit.
