2. Smart Grid Distribution - Requirements
Flexible and Scalable
Secure
Self-healing
Adaptive (capacity, power flow, load, protection)
Capable of Supporting DER
Integrate with AMI, DMS, OMS, GIS, etc
Built around Modern Communications Systems
Plug-and-Play and Self-diagnostic
Upgradeable and Remotely Administered
Precision Curve Fitting – TCCs are equation based, and IntelliRupter has tight tolerances (+/- 2% in time and current versus a typical 5% or even 10% for other protection devices). Allows for easy (and automatic) protection setup by making small changes to the parameters used in the relay equation.
Automatic Protection Setup – One IntelliRupter can communicate (via the WAN radio, for example) it’s protection settings to the next downline IntelliRupter, and the downline IntelliRupter can then automatically generate an appropriate set of protection curves.
Communication Enhanced Coordination – When a fault occurs, SpeedNet radio is fast enough (and takes advantage of the priority messaging capability) to communicate it’s protection settings with upline devices to ensure the proper device trips, even when they are not fully or properly coordinated using TCCs.
Advanced Adaptive Protection – Builds even further on the above technology. Dynamically generates new protection settings based on system reconfiguration!
SpeedNet radio is the enabler of this advanced protection capability.

Distributed Intelligence
IntelliTEAM II IS Smart Grid. Works with multiple source, multiple contingencies, multiple loads.
Today, IT actions are event driven – LOV, fault. It is self-healing, adaptive, and scalable. Will migrate to an optimization - Next step is to balance the load, optimize feeder loading. Already have the distributed intelligence in place and ability to monitor the system conditions.
Restoration on real circuits is a massive process. With IT II many things are happening in parallel, not waiting for some global algorithm.

7. IntelliTEAM II
With IntelliTEAM II, teams coordinate actions to automate systems of virtually any size

8. IntelliTEAM II – What is It?
Rule-based software system
Does not require custom programming
Does not require extensive validation and testing
No reprogramming when new devices are added to the grid or when the topology of the electrical system is rearranged – just re-configure controls
Virtually maintenance-free and self-diagnostic
Communicates using standard protocols (DNP) over any communications medium

21. IntelliRupter® PulseCloser – A High Performance Fault Interrupter

22. Pulseclosing Technology
Test to see if the line is still faulted
Don’t stress or damage the power system equipment
Don’t cause voltage sags for upstream customers
CLOSING ANGLE 118° AFTER VOLTAGE ZERO
Voltage
Current
This Is the Pulse!
Take advantage of high performance control and mechanism to perform point-on-wave closing
target is 118° after voltage zero for pulsing (algorithm actually works properly for closing in the range of 90 degrees to 140 degrees) to take advantage of fault asymmetry and create a MINOR LOOP of fault current
Initiates a VERY fast close-open operation
open before current reaches zero
current pulse is 3 to 8 ms
A pulseclosing operation is ALWAYS a close-open
the pulse is analyzed, then…
IntelliRupter stays open or closes pending results

43. The Future Distribution System – Key Challenges
Significantly more complex protection due to widespread use of protective devices, DER, changing feeder topology, etc.
Frequent reconfiguration of the power grid
Unpredictable power flow
