Recent research led by Katarzyna Markowska from the Department of Transport Systems, Traffic Engineering and Logistics at the Silesian University of Technology, addresses critical challenges in power quality and electromagnetic compatibility within shipboard electric power systems (SEPS). The study, published in the International Journal of Electrical Power & Energy Systems, focuses on enhancing the operational efficiency of self-propelled floating cranes, particularly the “EXPERT 3.”
As marine industries increasingly rely on dynamic positioning (DP) capabilities, ensuring high power quality becomes essential. Markowska’s research delves into the intricacies of voltage and current waveform distortions that can arise from the use of variable-frequency drives (VFDs) in converter-based propulsion complexes (CBPCs). These distortions can lead to operational inefficiencies and increased maintenance costs, making it crucial for operators to address these issues.
The study employs a refined MATLAB model that simulates various scenarios within SEPS, allowing for a thorough analysis of harmonic current and voltage distortions, reactive power generation, and power factor. By validating distortion indicators at ship synchronous generators, the research ensures compliance with international maritime standards at critical points in the power system.
One of the standout contributions of this research is the proposal of an improved controlled filter-compensating device (CFCD). This innovative approach incorporates a resonance filter and a controllable reactor compensator, enhancing the efficiency of VFD configurations. Markowska notes, “Our findings demonstrate that the CFCD can significantly mitigate harmonic distortions, leading to more stable and reliable operations in marine environments.”
The implications of this research extend beyond just technical improvements; they present commercial opportunities for companies involved in marine engineering, shipbuilding, and electrical systems design. By adopting these advanced methodologies and technologies, businesses can enhance the performance of their vessels, reduce operational costs, and comply with stringent international standards.
In summary, this research not only addresses pressing technical challenges in shipboard power systems but also opens the door for enhanced commercial viability in the maritime sector. As industries continue to seek more efficient and sustainable operations, the insights from Markowska’s work could play a pivotal role in shaping the future of marine power systems.
