Intelli. TEAM II • With Intelli. TEAM II, teams coordinate actions to automate systems

Intelli. TEAM 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 reconfigure controls • Virtually maintenance-free and self-diagnostic • Communicates using standard protocols (DNP) over any communications medium © 2009 www. sandc. com

Intelli. TEAM II – Key Features • Intelli. TEAM restores power in seconds without overloading any section of the power grid • Can handle multiple fault contingencies • Restores power from alternate sources as long as there is capacity left, whether the power source is conventional, DER, wind, storage, etc. • Intelli. TEAM supports islanding with Na. S storage systems. © 2009 www. sandc. com

Intelli. TEAM II Works with… non-S&C Devices via the Universal Interface Module (UIM) • Intelli. TEAM is an Open System • Allows a relay, recloser control, or switch control to be a part of an Intelli. TEAM system • UIM polls the External Device to acquire the data it needs to make Intelli. TEAM II logic decisions • Protective functions of the relay or recloser are not affected • Intelli. TEAM II takes over after the device locks out © 2009 www. sandc. com
