In recent modernisation of a large coal-fired power plant in Denmark, Solvina successfully conducted a grid compliance testing of the new excitation system. The work was a mix of theoretical studies and measurement and testing.
Solvina carried out:
- Simulation of grid compliance regarding fault ride through, PSS function, SC currents, stability margins
- Tuning of PSS and AVR in order to obtain optimum functionality within grid code boundaries
- Tuning of UEL in order to comply with grid code requirements
- Test and measurements on site as part of FAT for V&V and additional tuning.
The work required fine detail modelling of excitation control system that is of non-IEEE type.
