3.2 Definitions
3.2.1 area electric power system (EPS): An EPS that serves local EPSs. Note that, typically, an area EPS has primary access to public rights-of-way, priority crossing of property boundaries. etc., and is subject to regulatory oversight.
3.2.2 clearing time: The time between the start of the abnormal condition and the distributed resources’ (DR’s) ceasing to energize the area electric power system (EPS). It is the sum of the detection time, any adjustable time delay, the operating time for any interposing devices (if used), and the operating time for the interrupting device (used to interconnect the DR with the area EPS).
3.2.3 commissioning test: A test conducted when the equipment is installed to verify correct operation.
3.2.4 design test: See: type test.
3.2.5 detection time: The minimum length of time from the inception of the abnormal condition to the change in state of the device or function dedicated to controlling the interrupting device. Syn: processing time.
3.2.6 distributed generation (DC): Electric generation facilities connected to an area electric power system (EPS) through a point of common coupling (PCC): a subset of distributed resources (DR).
3.2.S electric power system ([PS): Facilities that deliver electric power to a load. Note that EPS may include generation units. See also: area electric power system (PS): local electric power system (EPS).
3.2.9 interconnection system (ICS): the collection of all equipment and functions, taken as a group. used to interconnect a distributed resources (DR) unit to an area electric power system (EPS).
3.2.10 interrupting device: A device capable of being opened and reclosed whose purpose is to interrupt faults and restore service or disconnect loads. These devices can be manual, automatic, or motor-operated. Examples include circuit breakers, motor-operated switches, and electronic switches.
3.2.11 inverter: A machine, device, or system that changes dc power to ac power.
3.2.12 island: A condition in which a portion of an area electric power system (EPS) is energized solely by one or more local EPSs through the associated points of common coupling (PCCs) while that portion of the area EPS is electrically separated from the rest of the area EPS.
3.2.13 local electric power system ([PS): An EPS contained entirely within a single premises or group of premises.
3.2.14 nominal: The value or range of a parameter being within expected norms or being the normal operating level of that parameter.
3.2.15 paralleling device: A device (e.g., circuit breaker) operating under the control of a synchronizing function to electrically connect two energized power sources together.
3.2.16 point of common coupling (PCC): The point where a local electric power system (EPS) is connected to an area EPS.
3.2.17 point of distributed resources (DR) connection: The point where a DR unit is electrically connected in an electric power system (EPS).
3.2.18 productIon test: A test conducted on every unit of equipment prior to shipment.IEEE 1547.1 pdf free download.
