Line distance protection REL670
Version 2.2
Analog, integer and double indication values are also
transferred through the EVENT function.
Generic communication function for Single Point
indication SPGAPC
Generic communication function for Single Point
indication (SPGAPC) is used to send one single logical
signal to other systems or equipment in the substation.
Generic communication function for measured
values MVGAPC
Generic communication function for measured values
(MVGAPC) function is used to send the instantaneous
value of an analog signal to other systems or equipment
in the substation. It can also be used inside the same
IED, to attach a RANGE aspect to an analog value and to
permit measurement supervision on that value.
Measured value expander block RANGE_XP
The current and voltage measurements functions
(CVMMXN, CMMXU, VMMXU and VNMMXU), current and
voltage sequence measurement functions (CMSQI and
VMSQI) and IEC 61850 generic communication I/O
functions (MVGAPC) are provided with measurement
supervision functionality. All measured values can be
supervised with four settable limits: low-low limit, low
limit, high limit and high-high limit. The measure value
expander block (RANGE_XP) has been introduced to
enable translating the integer output signal from the
measuring functions to 5 binary signals: below low-low
limit, below low limit, normal, above high limit or above
high-high limit. The output signals can be used as
conditions in the configurable logic or for alarming
purpose.
Insulation supervision for gas medium function
SSIMG
Insulation supervision for gas medium (SSIMG) is used
for monitoring the circuit breaker condition. Binary
information based on the gas pressure in the circuit
breaker can be used as input to the function. In addition,
the function can be used with an analog value of gas
pressure and temperature of the insulation medium and
binary inputs. The function generates alarms based on
received information.
Insulation supervision for liquid medium SSIML
Insulation supervision for liquid medium (SSIML) is used
for monitoring the oil insulated device condition. For
example, transformers, shunt reactors, and so on. Binary
information based on the liquid level in the circuit
breaker can be used as input to the function. In addition,
the function can be used with an analog value of liquid
level and temperature of the insulation medium and
binary inputs. The function generates alarms based on
the received information.

Circuit breaker condition monitoring SSCBR
The circuit breaker condition monitoring function
(SSCBR) is used to monitor different parameters of the
breaker condition. The breaker requires maintenance
when the number of operations reaches a predefined
value. For a proper functioning of the circuit breaker, it
is essential to monitor the circuit breaker operation,
spring charge indication or breaker wear, travel time,
number of operation cycles and estimate the
accumulated energy during arcing periods. Each SCCBR
function instance is made to be used with a 1-pole, 1-
phase breaker.
Fault locator LMBRFLO
The accurate fault locator is an essential component to
minimize the outages after a persistent fault and/or to
pin-point a weak spot on the line.
The fault locator is an impedance measuring function
giving the distance to the fault in km, miles or % of line
length. The main advantage is the high accuracy
achieved by compensating for load current and for the
mutual zero-sequence effect on double circuit lines.
The compensation includes setting of the remote and
local sources and calculation of the distribution of fault
currents from each side. This distribution of fault
current, together with recorded load (pre-fault)
currents, is used to exactly calculate the fault position.
The fault can be recalculated with new source data at
the actual fault to further increase the accuracy.
Especially on heavily loaded long lines, where the source
voltage angles can be up to 35-40 degrees apart, the
accuracy can be still maintained with the advanced
compensation included in fault locator.
Event counter with limit supervison L4UFCNT
The Limit counter (L4UFCNT) provides a settable
counter with four independent limits where the number
of positive and/or negative flanks on the input signal
are counted against the setting values for limits. The
output for each limit is activated when the counted
value reaches that limit.
Overflow indication is included for each up-counter.
Running hour-meter TEILGAPC
The Running hour-meter (TEILGAPC) function is a
function that accumulates the elapsed time when a
given binary signal has been high.
The main features of TEILGAPC are:
