1. A monitoring control apparatus in combination with transformer station equipment, the monitoring control apparatus comprising:
a hardware processor configured to:
display an alarm screen for notifying a plurality of abnormalities occurring in the transformer station equipment, the transformer station equipment provided in an electric power system;
select a first abnormality among the plurality of abnormalities;
calculate, for each of one or more other abnormalities except for the first abnormality among the plurality of abnormalities, a degree of association of the other abnormality with the first abnormality; and
extract the other abnormality as an associated abnormality associated with the first abnormality when the degree of association of the other abnormality is not less than a threshold,
wherein the alarm screen includes an associated alarm for notification of the extracted associated abnormality,
wherein the hardware processor is configured to, when a schematic diagram including a detection circuit for the first abnormality is identical to a schematic diagram including a detection circuit for the other abnormality, increase the degree of association of the other abnormality with the first abnormality by a first reference value.
