Energy Central announces new webinar: Eversource's Story - Transforming Direct Transfer Trip (DTT) with LTE – on March 9th, 2021

Denver, CO Feb 15, 2021  


    Denver, CO Feb 15, 2021 - On March 9th, Tim Callahan of Eversource, Isaac Maze-Rothstein of Wood Mackenzie and Warren Westrup of Sierra Wireless will discover how New England’s largest energy provider, Eversource, implemented an innovative DTT design using SEL’s 3505 RTAC and Sierra Wireless’ cellular gateways to communicate and control reliably over LTE.

    The wide-spread introduction of renewables (solar and wind generation) has been a tremendous benefit in helping to reduce greenhouse gases and diversify the energy supply. However, integrating these new distributed energy resources (DERs) into the grid is not without challenges.

    One of the most critical factors is proper coordination between utility substations and DERs to effectively clear a fault, preventing damage to equipment and ensuring the safety of line crews working on the affected area.

    Traditionally, this coordination has been through the use of leased telephone lines that interconnect protection equipment at both the substation and the DER site. Unfortunately, over the last several decades, telecom providers have moved away from copper lease lines to more advanced services.

    Replacement options like fiber optic cables or microwave communication links are available but can be very costly. Another option is cellular LTE technology, but with the critical nature of DTT, many utilities do not feel comfortable using it for the application.

    Listen in as we explore the challenges of integrating DERs into the Distribution grid; a cost-effective and reliable way to use LTE cellular for DTT; as well as what to look for in solution partners.
