GE Multilin G30 Generator Protection Relay

$1.00

Generator Protection Systems

Built on the industry-leading UR platform, the G30 provides advanced protection for small to medium-sized steam, hydraulic and combustion-turbine generators. The G30 is also well suited for applications where both the generator and transformer are in the same zone of protection, providing the required protection in one device. The G30 provides advanced communication with an integrated managed Ethernet switch, while supporting standard communication protocols including IEC 61850.

Key Benefits:

  • Complete protection for small to medium-sized generators and transformers
  • Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
  • Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
  • Combined generator and transformer protection
  • Robust network security enabling Critical Infrastructure Protection through user command logging, and dual permission access control
  • Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
  • High-speed peer-to-peer communications allowing reduction of relay-to-relay wiring and associated installation costs
  • An integrated large, full color display, provides real-time visualization and control of the protected bay, via a bay mimic as well as annunciator functionality and graphical visualization of phasors

Description


UR Switch Module:

In addition to providing high-speed connectivity directly to your Universal Relay, the UR Switch Module provides an additional 4 fiber Ethernet ports, for connection to other relays in the system as well as upstream connectivity. It also provides 2 RJ45 copper Ethernet ports which can be used to connect local devices such as PCs, meters, or virtually anything else in the system.

The UR Switch Module provides a simple way to add fully-managed Ethernet networking to your relays and devices without the need for additional hardware or a dedicated communications cabinet.

 

Interoperability with embedded IEC 61850

Use the G30 with integrated IEC 61850 to lower costs associated with generator protection, control and automation. GE’s leadership in
IEC 61850 comes from thousands of installed devices and follows on years of development experience with UCA 2.0.

 

The G30 has been designed for the protection, control, and management of small generators.

Applications:

  • Small to medium-sized generators typically driven be steam, gas or hydraulic turbines
  • Distributed generation (DG) interconnect protection
  • Combined generator and transformer in the zone of protection
  • Pumped storage generators

Communications:

  • Complete IEC 61850 Process Bus solution providing resource optimization and minimizing total P & C life cycle costs
  • Three independent 100Mbps Ethernet ports enable purpose specific LAN support that eliminates latency effect of heavy traffic protocols on mission critical communication services
  • Embedded IEEE 1588 time synch protocol support eliminates dedicated IRIG-B wiring requirements for IEDs
  • Direct I/O secures high-speed exchange of binary data between URs
  • Increase network availability by reducing failover time to zero through IEC62439-3 “PRP” support
  • Simplify set-up and configuration
  • Simplify diagnostic retrieval
  • Eliminate personnel in front of switchgear
  • WPA-2 security

The G30 provides advanced communications technologies for remote data and engineering access, making it the easiest and most flexible generator protection relay to use and integrate into new and existing infrastructures. Direct support for fiber optic Ethernet provides high-bandwidth communications allowing for low-latency controls and high-speed file transfers of relay fault and event record information. The available three independent and redundant Ethernet options provide the means to create fault tolerant communication architectures in an easy, cost-effective manner.

The G30 supports the most popular industry standard protocols enabling easy, direct integration into DCS and SCADA systems.

  • IEC 61850-9-2LE networked or IEC61850-9-2 Hardfiber process bus support
  • DNP 3.0 (serial & TCP/IP)
  • Ethernet Global Data (EGD)
  • IEC 60870-5-103 and IEC 60870-5-104
