N60 Network Stability and Synchrophasor Measurement System
MDS Wireless Communications
Many remote communities need to produce and manage all of the power required to support their loads. Providing the means to monitor the load of the entire system and optimize and dispatch the different types of generation available to meet load requirements is needed to reduce the overall electricity operating costs. The GE Microgrid Control System uses power generation information to select the most cost effective method of providing uninterrupted supply, while also providing the ability to control and optimize generation, storage and delivery of cleaner power.
DGT Distributed Generation Transfer Trip
Connecting Distributed Generation (DG) to the grid is required to meet the growing demand for power, while reducing carbon emissions produced by traditional coal generating stations. GE Digital Energy’s DGT enables the safe connection of Distributed Generation to the grid. Our fast, 2-way wireless network sends emergency disconnect signals from the utility to distributed generation sites. Trip confirmation status is returned back to the utility control center. This wireless infrastructure reduces communications costs while ensuring safe interconnection to the grid.

Our solutions increase reliability and optimization allowing utilities to monitor synchrophasor information, providing demand response initiatives to manage the overall power system. Digital Energy enables remedial action schemes, wide area protection, and fault and disturbance analysis tools which increase utility system reliability and customer service.

N60 Network Stability and Synchrophasor Measurement System
JungleMUX SONET Multiplexer
Smart transmission networks require a self-healing grid that identifies blackouts in the network and automatically re-routs power to the effected areas. GE Digital Energy’s solution detects outages and automatically reconfigures the network in real-time. GE’s JungleMux multiplexers create the communications backbone with a secure high-speed network. Over this network GE’s Multilin N60s share real-time information and intelligently shed load, or identify if additional generation is available elsewhere in the system and re-rout this available power to the blacked out areas.

   IEC61850 Process
   Bus Solution
The HardFiber Process Bus System represents a true breakthrough in the installation and ownership of protection and control systems, by reducing the overall labor required for substation design, construction, and testing. This solutions eliminates miles of expensive copper wires and thousands of individual terminations by using fiber optic cables. This reduces the labor required to upgrade or construct power substations by up to 50%.  

Digital Energy enables the efficient recovery of distribution system networks via fault isolation, sectionalization and power system restoration schemes. Digital Energy improves safety through the detection of fallen power lines and damaged underground cables with the use of Downed Conductor (Hi-Z) Detection and Incipient Cable Fault Detection.

Feeder Protection System
Detecting live downed power lines, which can cause fires and safety hazards, is a key requirement for a safer smart grid. GE Multilin’s Hi-Impedance Fault detection technology, developed over the past 20 years, provide utilities with the ability to detect when power lines have been knocked loose by falling trees branches or had their supporting poles knocked down by storms or vehicle accidents. Using a Safety-first approach, distribution utilities have the ability to detect and shut down these power lines before emergency and repair personnel approach these dangerous zones.
   URC Controller
Digital Energy enables the efficient recovery of distribution system networks via fault isolation, sectionalization and power system restoration schemes. GE’s Recloser Control System (URC) provides an intelligent, high speed and reliable DAS solution that enables fast service restoration and reduces customer outages. Our high speed, wireless capability provides peer to peer communications, enabling each URC to make intelligent decisions and respond quickly and efficiently to interruptions.  

Digital Energy provides solutions for Industrial, Commercial and Microgrid applications featuring communications that enable efficient control of the electrical protection system. Digital Energy enables demand side management in order to maximize overall plant efficiency, and delivers in-depth system analysis via Asset Monitoring.

Automation Logic
Energy Management
Digital Energy’s Load Shedding solution keeps critical processes running. The system utilizes C90 Automation Logic Controllers and the PMCS Energy Management System to identify when there are disruptions to the utility power supply, resulting in a shortage of power required to supply loads. Then, the system dynamically and safely sheds the least critical loads. This ensures that processes essential to production are unaffected, thereby reducing the costs associated with downtime.
