In newbuildings and conversions of ships, electrical power quality and harmonic distortion (THD) analysis are crucial for operational safety – especially with regard to the requirements of classification societies such as Lloyd's Register, RINA, ABS or DNV.
PQ ENGINEERING offers precise grid simulations with DIgSILENT PowerFactory to ensure compliance with these limits already in the planning phase.
What we simulate:
- Harmonic Distortion (THD)
- Generator load in different load scenarios
- Effects of the Shore connection
- Feedback from frequency converters and non-linear loads
Benefits for shipyards and planners:
- Early clarity about critical network areas
- Securing class requirements
- Avoiding expensive retrofitting
- Verification of filter measures before implementation
If the THD limit is exceeded, we supply customized filter solutions (passive/active) and support the implementation – up to final acceptance by the class.
Simulation instead of surprise – with PQ ENGINEERING to a safe ship class!
