New excitation concepts for turbine generators

Today, there are two major influences on the life-cycle of turbine generators. The integration of volatile energy generation and the impact of liquid natural gas (LNG) lead to new operation conditions. Gas turbine systems increasing in importance. To modify synchronous generators and motors to fit new requirements, a closer look onto the excitation system is inevitable. The exciter has a major influence on the dynamics of the system. Therefore, a new excitation concept for turbine generators is discussed in the paper at hand.
