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 (MVGGIO)
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-high limit or above
high limit. The output signals can be used as conditions in the
configurable logic or for alarming purpose.
9. Basic IED functions
Time synchronization
The time synchronization source selector is used to select a
common source of absolute time for the IED when it is a part
of a protection system. This makes it possible to compare
event and disturbance data between all IEDs in a station
automation system.
10. Human machine interface
Human machine interface
The local HMI is equipped with a LCD that is used among
other things to locally display the following crucial information:
• Connection of each bay, respecting the two differential
protection zones and the check zone. In the Parameter
Setting Tool the user sets individual bay names to
facilitate the identification of each primary bay for station
personnel.
• Status of each individual primary switchgear device, for
example, open, closed, 00 as intermediate state and 11
as bad state. In PCM600 the user sets the individual
primary switchgear object names to facilitate the
identification of each switchgear device for the station
personnel.
The local HMI is divided into zones with different functionality.
• Status indication LEDs.
• Alarm indication LEDs, which consist of 15 LEDs (6 red
and 9 yellow) with user printable label. All LEDs are
configurable from PCM600.
• Liquid crystal display (LCD).
• Keypad with push buttons for control and navigation
purposes, switch for selection between local and remote
control and reset.
• Isolated RJ45 communication port.
