Alstom/ GE 889 Generator Protection System

GE 889 Generator Protection devices provide innovative solutions for the protection, control and monitoring of generator assets. Generator protection is critical to maintaining maximum uptime in the generating facility and providing vital protection of the generating unit. From the protection and control of utility generators to ensuring safe interconnection of renewable energy sources, to synchronization and load shedding solutions using advanced automation, GE maximizes asset reliability and operational life.
GE’s advanced generator protection applications significantly reduce installation and maintenance costs by utilizing the Multilin HardFiber IEC 61850 process bus solution.

The Multilin 889 relay, a member of the Multilin 8 Series protective relay platform, has been designed for the protection, control, monitoring and management generators and in-zone transformers used in both industrial and utilities applications.
The Multilin 889 provides advanced, high-speed protection, extensively customizable programmable logic, and flexible configuration capabilities, to maximize the operational performance and life of critical generators.
Equipped with the latest in advanced communications, the Multilin 8 Series supports IEC 61850 Edition 2 ensuring simplified device integration and dual communication ports with IEC 62439/PRP, enabling users to achieve zero latency in communications for high reliability network architectures, ensuring complete asset monitoring and control.

Key Benefits
• Enhanced generator protection algorithms provide sub-cycle differential protection, ensuring faster fault clearing times for reduced generator damage
• Dedicated generator monitoring and control functions providing mission critical operational data to enable a pro-active maintenance approach
• Additional overall generator-transformer differential (87O) providing additional back-up protection
• Advanced differential protection for both generator and in-zone transformer
• Industry standard cyber security tools such as AAA, Radius, RBAC and Syslog enabling NERC/CIP requirements
• Draw-out design simplifies testing and increases process uptime
• Optional Wi-Fi minimizes system configuration and facilitates safe relay programming and diagnostic retrieval
To simplify the migration and upgrade from an existing SR 489 protection relays, retrofit kits have been developed which significantly simplify the upgrade process.
