摘要：
The traditional power frequency AC transmission mode is limited by the charging reactive power of long-distance submarine cables, and the DC transmission mode is restricted by the construction and maintenance cost of the offshore converter station. The flexible fractional frequency transmission system greatly increases the transmission capacity as well as the transmission distance by reducing the transmission frequency, and is competitive in the field of high-efficiency offshore wind power transmission. This paper firstly discusses the advantages of the flexible frequency fractional transmission system. And then, it describes the construction planning technology with frequency optimal selection and the stability analysis method with the different frequency interaction characteristics in detail. Furthermore, it analyzes how the frequency change influences the characteristics of key fractional frequency equipment, and focuses on the comparison between ferromagnetic AC/AC converter and power electronic converter. Finally, it expounds the prospect of some technical difficulties, such as static, dynamic as well as electromagnetic transient characteristics analysis, prototype development and system validation. © 2023 Automation of Electric Power Systems Press.
