Modernization of Protection and Control of Turbine Generators
The challenge
Turbogenerators 3 and 4 are essential for:
- To guarantee steam supply to external consumers.
- To supplement the factory's exhaust steam.
- To provide electricity for internal consumption and sale (cogeneration).
However, its protection panels used obsolete electromechanical relays that had already reached the end of their useful life. This equipment caused false faults, resulting in economic losses due to generation deficits and limitations on exports. The reliability and safety of the operation were at risk.
The solution
Comprehensive modernization of the Turbogenerator protection and control system..
A comprehensive upgrade of the protection and control system was carried out, replacing obsolete equipment and consolidating all functions in digital protection relays.
Key Actions:
- Removal of old electromechanical relays.
- Complete configuration of protections on the multifunctional relay.
- Development of CAD blueprints and configuration parameters.
- Reconfiguration using GE Enervista software.
- Continuity, insulation, and online operation testing.
- Comprehensive labeling of the installation to facilitate operation and maintenance.
The benefits
Correction and control of production processes, ensuring the objectives of the business process such as the sale of energy.
- More robust and efficient system.
- Reduced control wiring.
- Advanced generator protection with digital technology.
- Operational safety guaranteed and complying high standards.
- Reduced synchronization times, optimizing operation.
- Reduced economic losses due to failures and unscheduled downtime.
Impact on the plant
Reliability in the supply of energy for local consumption as well as reduction of operational risk and unexpected downtime.
The upgrade ensured that the turbogenerators operate with a modern, reliable and safe control system, guaranteeing the continuity of power generation, reducing risks and increasing the capacity for electricity export.
