Transceiver Interface for Power System Monitoring
First Claim
1. A system for providing power system information to a monitoring scheme, comprising:
- a monitoring scheme associated with an electric power system;
a faulted circuit indicator associated with the electric power system, comprising;
an acquisition circuit configured to monitor a power system condition;
a processor in communication with the acquisition circuit configured to detect an event on the electric power system based on the power system condition; and
,a radio transmitter in communication with the processor and configured to transmit a status message upon detection of the event;
a transceiver interface associated with the electric power system, including;
a radio receiver configured to receive the status message from the faulted circuit indicator;
a logic module in communication with the radio receiver, configured to compare the status message against other power system information and communicate the status message to a transceiver; and
,a transceiver in communication with the logic module and configured to transmit the status message to the monitoring scheme.

Abstract
A system and method for filtering electric power system data communicated from faulted circuit indicators (FCIs) and at least one other source before the electric power system data is further communicated to a monitoring system such as SCADA. The power system data from the FCIs may include an event such as a fault on the electric power system. To avoid sending incorrect or excess information along to the monitoring system, the present disclosure describes a system and method for comparing data from the FCIs against electric power system data gathered either directly from the electric power system or from an intelligent electronic device (IED). If the two sets of data agree, then the information is passed on to the monitoring system. The FCIs may communicate to a transceiver interface periodically, upon detection of an event, and/or upon interrogation by the transceiver interface.

43. A method for reducing an amount of communication from faulted circuit indicators to a monitoring system of an electric power system including a transceiver interface for filtering status messages from the faulted circuit indicators in communication with an electric power system and sending electric power system information to the monitoring system, the method comprising the steps of:
-
detecting a power system event by the faulted circuit indicator; transmitting a status message to the transceiver interface; receiving power system information by the transceiver interface; comparing the status message against the power system information; and transmitting the status message to the monitoring system.
