Multilin G30

Protection for Small to Medium Generators Combined Generators and Transformers

The G30 generator 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. 

Key Features

Monitoring & Metering

  • 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

Advanced Automation 

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.

Communication 

  • 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

Advanced Communication

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 Ed. 1/Ed. 2 with 61850-9-2 (Process Bus) and 61850-90-5

  • 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)

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.

The UR Switch Module includes all of the management and features that come with all MultiLink managed switches, and can be easily integrated into a network that has other Ethernet switches.

When used in a ring topology with other UR Switch Modules or MultiLink Switches, the UR Switch Module can be configured to use MultiLink’s Smart RSTP feature to provide industry-leading network recovery for ring topologies, at a speed of less than 5ms per switch. 

Interoperability with Enbedded IEC 61850

Use the G60 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 G60’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.

Sofeware & Security

Cyber Security - CyberSentry UR (FW v7.4xx)

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:

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 G60 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 G60 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.

The G30 is the single point for protection, control, metering, and monitoring in one integrated device that can easily be connected directly into HMI or SCADA monitoring and control systems like Viewpoint Monitoring as shown.
