Different functions developed for UFLS Module:

Under frequency Load / Generation Shedding system is to shed discrete amounts of load / generation in times

of power system under frequency in order to arrest the decline of the system frequency, or if this is not

possible, then to split the network into predefined Islands if generation exists within the respective Island

definition.

Purpose : The purpose of the Under frequency Application is to pre determine the load / generation to be

shed against each under frequency stage and to set up “paths”, via latching relays at the RTU, through which

the under frequency relay contacts will initiate the tripping of the local station breakers. The setting up of the

load “paths” is determined by means of a “Priority List” of feeders.

If an under frequency event has been detected and remains, There is no power supply to the Switching

stations and the bus bar voltage(s) indicate no voltage. In such case Circuit stripping should be enabled to the

station after prior permission from the operator.

If the system frequency has recovered to a value above the Restoration Frequency (“RFreq”) set point,

typically set to 49.5 Hz, the “Under frequency Application” will provide an alarm to the operator indicating that

the system frequency has recovered sufficiently to start restoration and, on command from an operator,

commence restoring the loads / feeders by closing the breakers which tripped during the under frequency

event in the reverse priority order as set in the priority list.

The data required for under frequency load shedding is imported from excel (Comma separated value csv)

file to the avanti database in Network manager application servers.
