Intelligent Direct Transfer Trip (DTT) Leveraging Cellular Communications

ABOUT THIS EVENT

This webinar will focus on an Intelligent Direct Transfer Trip (DTT) solution using redundant cellular communications being deployed by today’s leading utilities.

Traditionally, Direct Transfer Trip (DTT) signals are sent between substations and remote distributed generation (DG) sites using leased copper telephone lines. If the DTT communication is interrupted, then these DTT systems automatically disconnect the DG site from the power grid. Reliable communication is crucial to avoid unwanted disconnections of DG sites, especially renewable energy power sources. Leased copper lines, however, are becoming less reliable, leading to unwanted disconnection of DG sites. Installation of fiber is not always feasible due to costs.

Join Madison Gas & Electric and Siemens Digital Grid as we discuss a recommended approach of providing intelligent DTT signals using redundant cellular communications channels.

The following topics will be covered:

• Why is there a need for a different approach to DTT?
• What makes a cellular solution desirable?
• What is new and novel in this approach?
• What are a DTT system’s design features? And what does a system deployment look like?
