GE N60 - Phasor Measurement Unit

GE Multilin N60 Network Stability and Synchrophasor Measurement System 5-113
5 SETTINGS 5.4 SYSTEM SETUP
5
The switch element has direct hard-coded connections to IEC 61850 model as shown in the logic diagram. This allows
remote open/close operation of each switch, using either CSWI or XSWI IEC 61850 logical nodes. IEC 61850 select-
before-operate functionality, local/remote switch functionality along with a blocking open/close commands are provided.
Note that IEC 61850 commands are event-driven and dwell time for these is one protection pass only. If you want to main-
tain close/open command for a certain time, do so either on the contact outputs using the "Seal-in" setting or in FlexLogic.
5.4.6 PHASOR MEASUREMENT UNIT
a) MAIN MENU
PATH: SETTINGS  SYSTEM SETUP  PHASOR MEASUREMENT UNIT
The N60 is provided with an optional phasor measurement unit feature. This feature is specified as a soft-
ware option at the time of ordering. The number of phasor measurement units available can also depend
on this option. Using the order code for your device, see the order codes in chapter 2 for details.
UR Synchrophasor Implementation
PHASORS are used within protection relays. If these phasors are referenced to a common time base they are referred to as
a
SYNCHROPHASOR. A vastly improved method for tracking power system dynamic phenomena for improved power system
monitoring, protection, operation, and control can be realized if Synchrophasors from different locations within the power
system are networked to a central location.
