Generator excitation and voltage control

Modernize excitation equipment for synchronous generators and integrate it reliably into grid operation, protection and control concepts.

Excitation system functions

VoltageRegulate generator voltage within the intended operating range.
Reactive powerImplement reactive-power or power-factor setpoints in a coordinated manner.
Grid operationTake synchronization, protection and control interfaces into account.

Excitation as a system function

Generator excitation directly affects voltage and reactive power. It must therefore be coordinated with generator parameters, the grid connection and the plant operating modes.

For modernization projects, we assess the existing excitation unit, measurement system, protection equipment and required setpoint interfaces.

Practical implementation

Clearly parameterized and documented

The implementation combines the excitation unit, measured values and plant requirements into a solution that is straightforward to operate.

Assessment: Review the existing excitation system and generator data.
Integration: Connect measurement, protection and control systems cleanly.
Commissioning: Commission setpoints and operating behaviour.
