The N60 Network Stability and Synchrophasor System is a flexible device intended for the development of load shedding, Remedial Action, special protection schemes and wide area monitoring (synchrophasors). Special protection schemes are unique to each installation and are carefully matched to a given system topology, operating practices, system and protection philosophies of a given utility. The N60 provides an exceptionally flexible platform to easily integrate and facilitate special protection schemes.

What's New in the N60:

• Decrease blackouts - By identifying network instabilities and taking fast preventative action
• Higher utilization of existing investments - Increase power transfer capability on existing lines
• Increase power system performance - Decisions & control based on fast communications, and information exchange
• Optimized data sharing and utilization - Complements existing control & protection by sharing information with existing systems for enhanced power system security
• Contingency planning through continuous synchrophasor data collection and postmortem analysis
• Reliable and secured network - Improved state estimation for SCADA for optimum system wide load shedding and remedial action schemes
• Enhanced and automated mitigation for system critical conditions such as power system dampening and loss of synchronism reducing outages
• GOOSE Synchrophasor – PMU transmission over IEC61850 and Goose messages
