Comprehensive Excitation and Protection solutions for Steam Turbine Synchronous Generators

We participate in the commissioning of excitation and protection systems for synchronous generators within steam turbine sets. Our focus is on functional verification, control loop tuning, and the testing of protection functions to ensure the stable, safe, and long-term reliable operation of the equipment.

WE OFFER

Benefits of Our Approach to Generator Excitation and Protection

1.

Reliability During Commissioning

We perform detailed functional verification of the generator excitation and protection systems under real operating conditions. Thanks to systematic testing, we minimize risks during the initial start-up and the transition to continuous operation.

2.

Verification of Rapid and Correct Protection Response

We test protection behavior during limit and fault conditions in compliance with the design, standards, and grid operator requirements. We place emphasis on selectivity, correct timing, and the safe disconnection of the generator.

3.

Control Tuning Tailored to the Specific Machine

We adapt excitation and control parameters to the specific generator, turbine output, and operating conditions. We do not work with generic values, but with data corresponding strictly to the specific technology.

 

4.

Diagnostics, Measurements, and Documentation

We perform measurements of electrical quantities, waveform recordings, and test data archiving. The output consists of clear technical reports for both the customer and the generator manufacturer.

Verification of Generator Excitation and Protection Functions in real operation

During generator commissioning, we conduct functional tests of the excitation and protection systems under defined operating and limit conditions. We monitor the dynamic response of the control loops, protection behavior, and interactions with the control system and the grid. The output consists of measured waveforms and records that serve as the basis for the final evaluation and handover of the equipment for operation.

Generator Excitation Control

Testing the dynamic response of the excitation control during load and voltage changes.

Generator Protection

Verification of protection functions during limit and fault conditions in compliance with the design and standards.

Stability and Synchronization

Evaluation of generator stability during synchronization and grid operation.

 

Integration into Control Systems

Verification of interfaces with the TCS, switchgear, and supervisory systems, including communication and signals.
