“…15 Al-Amin et al probed the use of a silicone-based synthetic ester as an insulating uid in transformers and found that this uid had the capacity to reduce operational risks in transformers. 16 Thiena et al investigated palm and coconut oils and found that their breakdown voltages (BDV) were comparable to mineral oil. 17 Liao et al showed that though the natural ester, BIOTEMP, had higher acidity and absolute humidity upon aging, its lower relative humidity ratio is bene-cial for maintaining the AC breakdown voltage higher than that of mineral oil.…”

“…Hence, the incorporation of these losses in transformer DTR modelling is compulsory for accurate HST and TOT determination. Similarly, the transformer oil viscosity can vary significantly with temperature and this variation depends on the type of oil used and the variation is maximum for low ambient temperatures, which is common in OWPP applications [55]. The development of TOT and HST is therefore influenced by the type of transformer oil because viscosity affects the flow patterns and convective cooling.…”

With recent developments and cost reduction, offshore windfarms are set to lead the energy markets of the west by 2030. This development can further be accelerated if the wind intensive periods can be utilized efficiently by optimizing the limited network capacity and if the energy output is increased during contingency outages. Therefore, dynamic rating operation of components that are primary system bottlenecks becomes crucial. This paper identifies potential bottlenecks in offshore windfarm export systems and provides an extensive state-of-the-art review of dynamic thermoelectric models which are applicable for real-time loadability assessment of the identified components. The loadability of these components is directly dependent on their thermal state, which is evaluated based on analytical solutions of the dynamic thermoelectric model, including the complicated heat transfer and temperature development phenomena in the identified components. Moreover, potential risks of using these models for offshore windfarm applications are also identified.

“…However, liquid filled transformers are more efficient and reliable [57]. As such, there is significant research into alternative, non-flammable transformer insulating fluids, e.g., [58]. These have been demonstrated in MV:HV transformers [59] for the specific application of lightweight offshore substation modules.…”

Electrical Components for Marine Renewable Energy Arrays: A Techno-Economic Review

et al. 2017

View full text Add to dashboard Cite

This paper presents a review of the main electrical components that are expected to be present in marine renewable energy arrays. The review is put in context by appraising the current needs of the industry and identifying the key components required in both device and array-scale developments. For each component, electrical, mechanical and cost considerations are discussed; with quantitative data collected during the review made freely available for use by the community via an open access online repository. This data collection updates previous research and addresses gaps specific to emerging offshore technologies, such as marine and floating wind, and provides a comprehensive resource for the techno-economic assessment of offshore energy arrays.
