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.

Why is Distributed Control Better for DA? Speed Increased Security Lower Lifecycle Cost Flexibility and Scalability Reliability Lower Communications Bandwidth Demand

Enabling the Smart Grid Today – S&C Products IntelliTEAM II Automatic Restoration System Universal Interface Module IntelliRupter PulseCloser SpeedNet Radio Next Generation IntelliTEAM Other products IntelliCAP Capacitor Controls NaS Battery Energy Storage CES (Community Energy Storage) Emphasis on keeping the technology up-to-date. The basic foundation has been proven in the field for over 10 years and hundreds of “system” installations, but new features, new technology, and new devices (SpeedNet, IR) keep it on the leading edge of DA.

IntelliTEAM Concept Original IntelliTEAM Introduced in 1996 Limited to 2 sources of power Must contain an open switch No radial circuits Real-time load data to prevent overloads Automatic return to normal configuration DNP 3.0 protocol Distributed intelligence

IntelliTEAM II – Evolution Self-healing Fault Isolation and Circuit Restoration System Introduced in 2002 Proven technology used by over 130 utilities Easily applied to complex feeder systems Accommodate more than two sources of power Accommodate multiple tie points to adjacent feeders Real-time load data to prevent overloads 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.

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

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 IntelliTEAM II IS Smart Grid.

IntelliRupter® PulseCloser – A High Performance Fault Interrupter

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
