Description

Processor Unit PM861

Processor Unit PM861

 

If required, this CVGAPC function can be used in directional comparison protection scheme for the power line protection if communication channels to the remote end of this power line are available. In that case typically two NegSeq overcurrent steps are required. One for forward and one for reverse direction. As explained before the OC1 stage can be used to detect faults in forward direction.

The built-in OC2 stage can be used to detect faults in reverse direction. However the following shall be noted for such application:

• the set values for RCADir and ROADir settings will be as well applicable for OC2 stage

• setting DirMode_OC2 shall be set to Reverse • setting parameter StartCurr_OC2 shall be made more sensitive than pickup value of forward OC1 element (that is, typically 60% of OC1 set pickup level) in order to insure proper operation of the directional comparison scheme during current reversal situations

• start signals from OC1 and OC2 elements shall be used to send forward and reverse signals to the remote end of the power line • the available scheme communications function block within IED shall be used between multipurpose protection function and the communication equipment in order to insure proper conditioning of the above two start signals Furthermore the other built-in UC, OV and UV protection elements can be used for other protection and alarming purposes.
