Custom Electronics Inc. (CEI) and GridEdge Networks have partnered to launch a 69-kV distributed era permissive (DGP) resolution that permits safer, more cost effective integration of distributed vitality assets (DER) into utility grids.
The brand new system addresses a crucial security problem: defending utility employees and gear when DERs are disconnected from the grid and kind an unintentional island that will trigger harmful energy fluctuations.
“As extra impartial energy producers connect with the electrical grid, utilities face new security dangers when utility crews work on energy traces,” mentioned Nachum Sadan, CEO of GridEdge Networks. “Our DGP system supplies failsafe safety by mechanically disconnecting renewable vitality sources when grid faults happen, eliminating the danger of unintentional islanding. This solves a crucial grid security downside.”
Not like conventional direct switch journey (DTT) techniques that make the most of an exterior communications methodology resembling fiber, GridEdge’s DGP expertise leverages the prevailing wires and is available, low value and inherently failsafe. The system meets the IEEE 1547-2018 interconnection commonplace and is acknowledged in IEEE 1547.1-2020 part 5.10.3 as a “Powerline Performed Permissive Sign” methodology.
The 69-kV resolution makes use of commonplace coupling capacitor voltage transformers (CCVTs) to transmit indicators, eliminating the necessity for costly fiber optic installations that may value tons of of hundreds of {dollars} relying on distance. This innovation makes renewable vitality tasks extra economically viable whereas sustaining the very best security requirements, as it’s a dependable and cost-effective different to fiber.
CEI brings six many years of experience in high-voltage capacitors and energy techniques to this strategic manufacturing partnership, with merchandise deployed in army, business and industrial purposes worldwide. “This collaboration leverages our confirmed high-voltage manufacturing capabilities to assist the clear vitality transition,” mentioned Michael Pentaris, President and CEO at CEI. “The expertise supplies important infrastructure for utilities and renewable vitality builders to function safely and effectively.”
The 69-kV DGP resolution was developed in shut collaboration with U.S. utility companions and is straight away obtainable for sub-transmission purposes. The answer contains gear and providers. GridEdge supplies an entire turnkey deployment together with system commissioning and operator coaching.
