Glencane Bioenergia was looking for a solution to ensure continuous uptime of the plant's main process and avoid costly production downtime. They also sought to optimize the use of electricity in the plant and improve the control of the contracted power demand to avoid penalties from the utility.
To ensure continued power supply to the most important loads in the plant, ABB proposed an authentic IEC 61850 load-shedding solution, by integrating Relion® protection relays, the load-shedding controller PML630 and the Substation Management Unit COM600S. The seamless integration of these devices ensures a high performance load-shedding solution. The load-shedding function prevents a total shutdown in plant power distribution. This is done via switching off non-critical loads and securing power to critical loads accurately and quickly, ensuring a total response time within a few tens of milliseconds.
To ensure power system reliability and performance, the compact solution utilizes the benefits of horizontal GOOSE-based communication technology between the protection and control devices. GOOSE (Generic Object Oriented Substation Events) is part of the IEC 61850 standard for power system automation.
Customer benefits include fast return on investment - in about seven months, and secured continued power supply to the most important loads.
