The G30 generator protection system provides comprehensive protection for small to medium-sized steam, hydraulic and combustion-turbine generators as well as applications that have both the generator and transformer in the same zone of protection. The G30 is ideal for protecting single and multi-pole generators with single or split-phase winding configurations of generators. The G30 includes advanced automation and communication capabilities, extensive I/O options, and powerful fault recording features that can simplify fault and disturbance troubleshooting and minimize generator downtime. As part of the UR family, the G30 provides superior protection and control.

• Metering - current, voltage, power, energy, frequency
• Oscillography – analog and digital parameters at 64 samples/cycle
• Event Recorder - 1024 time tagged events with 0.5ms scan of digital inputs
• Data Logger - 16 channels with sampling rate up to 1 sample / cycle
• Setting for security audit trails for tracking changes to G30 configurations

The G30 incorporates advanced automation features including powerful FlexLogic™ programmable logic, communication, and SCADA capabilities that far surpass what is found in the average generator relay. The G30 integrates seamlessly with other UR relays for complete system protection, including unit and auxiliary transformers, and balance of plant protection.

Key Features

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, HSR or dual HSR support

Advanced Communications

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 or IEC 61869 point-to-point or 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
• Modbus RTU, Modbus TCP/IP
• HTTP, TFTP, SFTP and MMS file transfer
• Redundant SNTP and IEEE 1588 for time synchronization
• PRP as per IEC 62439-3
• Supports Routable GOOSE (R-GOOSE)

Interoperability with Enbedded IEC 61850

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

The G30’s IEC 61850 Process Bus module is designed to interface with the Multilin HardFiber System, allowing bi-directional IEC 61850 fiber optic communications. The HardFiber System is designed to integrate seamlessly with existing Universal Relay applications, including protection functions, FlexLogic, metering and communications. Learn more

The G30 can also connect to GE Vernova MU320 or third-party merging units using standard IEC 61869 or IEC 61850-9-2LE communication protocols.

CyberSentry enables UR devices to deliver full cyber security features that help customers to comply with NERC CIP and NITIR 7628 cyber security requirements through supporting the following core features:

Secure FW upgrade

UR FW files v7.9 and up now include a hash code that allows for authentication prior to being used for upgrading UR devices.

Password Complexity

Supporting up to 20 alpha- numeric or special characters, UR passwords exceed NERC CIP requirements for password complexity. Individual passwords per role are available.

AAA Server Support (Radius)

Enables integration with centrally managed authentication and accounting of all user activities and uses modern industry best practices and standards that meet and exceed NERC CIP requirements for authentication and password management.

Role Based Access Control (RBAC)

Efficiently administrate users and roles within UR devices. The new and advanced access functions allow users to configure up to five roles for up to eight configurable users with independent passwords. The standard “Remote Authentication Dial In User Service” (Radius) is used for authentication. 

Event Recorder (Syslog for SEM)

Capture all cyber security related events within a SOE element (login, logout, invalid password attempts, remote/local access, user in session, settings change, FW update, etc), and then serve and classify data by security level using standard Syslog data format. This enables UR devices integration with established SEM (Security Event Management) systems.

EnerVista™ Software

The EnerVista™ suite is an industry-leading set of software programs that simplifies every aspect of using the G30 relay. The EnerVista™ suite provides all the tools to monitor the status of the protected asset, maintain the relay, and integrate information measured by the G30 into DCS or SCADA monitoring systems. Convenient COMTRADE and Sequence of Events viewers are an integral part of the UR setup software included with every UR relay, to carry out postmortem event analysis and ensure proper protection system operation.
