Product Introduction

Compared with power frequency transmission systems, flexible low-frequency transmission helps increase linetransmission capacity, reduce voltage loss and fluctuation, decrease cable charging reactive power, and provide flexible power support to the grid. It has significant economic advantages in scenarios such as mid-to-long distance offshore wind power transmission, multi-island interconnection, urban grid partition interconnection, and large-scale wind and photovoltaic power base transmission in areas like “deserts, gobi, and wilderness". The flexible low-frequency transmission technology will lay an important foundation for the development and utilization of new energy in China, the safe, economical, and stable operation of the power system, and the construction of a new type of power system. It has broad social, economic, and ecological benefits. 

Compared with DC transmission systems, it does not require DC circuit breakers, is easy to transform, and has the advantage of convenient networking, particularly in the 70km-200km range. There is no need for offshore converter stations and it features easy maintenance, reduced construction and maintenance costs; and high reliability with no primary equipment bottlenecks.
