Abstract
An example of the present disclosure provides a protective relay inspection device including: a connection unit connected to a protective relay; and an inspection unit which, upon receiving a relay setting-providing signal including relay setting information for the protective relay via the connection unit, processes an inspection of a relay function of the protective relay on the basis of the relay setting-providing signal. Here, the inspection unit includes: a plan generation unit which generates inspection plan information for an automatic inspection function on the basis of the relay setting-providing signal; and an inspection processing unit which inspects the relay function of the protective relay on the basis of the inspection plan information.
Claims20
A device for inspecting a relay function of a protective relay, the device comprising:
- a connector connected to the protective relay;
- and
- an inspector configured to receive a relay setting providing signal including relay setting information of the protective relay via the connector, and to execute inspection of the relay function of the protective relay, based on the relay setting providing signal,
- wherein the inspector includes:
- a plan creator configured to create inspection plan information for an automatic inspection function based on the relay setting providing signal;
- and
- an inspection processor configured to inspect the relay function of the protective relay based on the inspection plan information,
- wherein the relay setting information includes information about at least one enabled relay element as at least some of a plurality of the relay elements provided via the relay function of the protective relay, and information about a trip condition of each enabled relay element,
- wherein the inspection plan information includes information about an inspection sequence of the at least one enabled relay element based on the relay setting information, a trip condition of each enabled relay element, at least one inspection target signal corresponding to the trip condition of each enabled relay element, and a trip critical period corresponding to each inspection target signal.
A device for inspecting a relay function of a protective relay, the device comprising:
- a connector connected to the protective relay;
- an inspector configured to receive a relay setting providing signal including relay setting information of the protective relay via the connector, and to execute inspection of the relay function of the protective relay, based on the relay setting providing signal;
- and
- inspection mode setting means configured to deliver an inspection mode request signal to the protective relay via the connector, based on an inspection start signal of the inspector,
- wherein the inspection mode setting means is configured to:
- when a current time reaches a predefined notification period after delivering the inspection mode request signal corresponding to the inspection start signal, deliver the inspection mode request signal to the protective relay via the connector;
- and
- deliver an inspection termination notification signal to the protective relay via the connector, based on an inspection termination signal of the inspector,
- wherein the relay setting information includes information about at least one enabled relay element as at least some of a plurality of the relay elements provided from the protective relay, and information about a trip condition of each enabled relay element.
