Ac transmission system for offshore power transmission and heating
The granted patent US12074438B2 outlines an innovative AC transmission system designed for efficient power transmission to offshore plants, particularly in the context of oil and gas extraction. The system comprises an onshore power station, an offshore plant, and a first subsea cable connecting the two. Additionally, it features at least one pipeline equipped with an electrical heating system, which is linked to the offshore plant via a second subsea cable. This configuration allows for the management of power flow and enhances the stability of the transmission system, especially during significant power load fluctuations or overvoltage conditions.
The patent also details methods for mitigating overvoltage in the AC transmission system. This includes monitoring power loads at the offshore plant and strategically connecting the electrical heating system to control the power factor. The system can adapt to changes in power demand by connecting the heating system to the onshore power station through the subsea cables when necessary. Furthermore, the patent describes the integration of a wind power plant into the system, which utilizes variable frequency drives to further regulate the power factor. Notably, the first subsea cable is specified to be at least 100 km long, emphasizing the system's capability for long-distance power transmission.
