Reliability for critical environments
A team of Electrodrives technicians traveled to the Soto de Ribera thermal power plant for a first-hand assessment of some operational issues affecting the equipment.
The installation includes two independent systems, each composed of a subsynchronous cascade and a resistor chopper as backup, used for the control of two 1,500 kW fans, one per system.
After replacing damaged mechanical components and correcting a faulty speed sensor, it was confirmed that the equipment, after more than 25 years of service, still maintains its original performance, demonstrating a level of reliability far above industry standards.
The consistency of this behaviour reflects the design philosophy inherited by Electrodrives from IES: “equipment built to last, withstand, and operate in scenarios where failure is not an option.”
Specialized technical support for legacy equipment over 30 years old
Soto de Ribera is currently undergoing a major energy transition, phasing out coal in favor of gas to leverage existing infrastructure. The goal is to maintain operations and ensure grid stability through the use of synchronous condenser systems.
Electrodrives continues fulfilling the commitments inherited from IES and from its customers. In a context where many industries choose to discard “old” systems, we commit to extending the service life of robust designs, supported by specialized engineering capable of providing long‑term technical support.
