Export Transformer Switching Transient Mitigation in HVDC Connected Offshore Wind Farms
IEEE Transactions on Power Delivery(2020)
摘要
An increasing number of offshore wind farms are connected to the public grid with large-scale HVDC links. The electrical transients caused by the energization of the export transformers appear more significant in the converter-driven offshore AC grid with low short-circuit power, than in direct AC grid connections. This may lead to a violation of the 2% voltage dip criterion, thus seriously affect...
