Delta Supervision Of Real Input Delspvc; Identification; Application - Hitachi Relion 670 Series Applications Manual

1MRK511407-UUS Rev. N
Imin: The minimum pickup level setting should be set as % of IBase. This setting enables the function to
start detecting delta. Typical setting is 10% of IBase.
MeasMode: To detect the mode of measurement; phase to phase or phase to ground.
OpMode: To select the mode of operation. For protection applications, this should be set to
Instantaneous 1 cycle old. Load supervision can be done using DFT mag mode.
DelI>: To detect the pickup value for instantaneous sample, RMS, DFT mag based delta detection. Set a
typical value of 200% of IBase to use this function as fault detection.
DeltaT: This setting defines the number of old cycles data to be used for delta calculation in RMS/DFT
Mag mode. Typical value is 2 cycles.
tHold: This setting defines the pulse length for supervision pickup signal. Typical value is 100 ms.
EnaHarm2Blk: This setting should be set to ON, to enable blocking for heavy inrush currents or other
sources of 2
Harm2BlkLev: This is the blocking level of 2
setting is 15% of fundamental signal.
EnStValAdap: This setting should be set to ENABLE in special networks where settings in the network
are adapted with respect to 3
Harm3Level: This is the set level of 3
should be modified. Typical setting is 15% of fundamental signal.
StValGrad: To modify the DelI> based on 3

Delta supervision of real input

Application

Delta supervision of real input DELSPVC is a general processed input delta supervision. It is used to
configure any processed inputs such as:
• Power (S)
• Active power (P)
• Reactive power (P)
• Thermal heat content (ɸ)
• Energy
The change over time of these quantities with respect to the old value can be supervised with this
function.
