MingYang Smart Energy has deployed energy storage technology at the 43MW Huian Quanhui offshore wind farm in China’s Fujian province.
The turbine manufacturer’s subsidiary, Quant-Cloud, developed the storage technology to enhance the typhoon resiliance capabilities of MingYang’s offshore wind turbines.
At the Huian Quanhui wind farm an energy storage system is installed in the tower of each turbine.
It marks the first installation of an energy storage system in the region’s typhoon zone, following the demonstration of MingYang’s MySE5.5MW typhoon-proof offshore turbine at Xinghua Bay offshore wind farm.
When a power outage is caused by typhoon, normal operation of the wind turbine’s yaw system has to be maintained to prevent excessive load on the grid, caused by yaw failure, said MingYang.
Backup power supply can ensure the continuous operation of the yaw system in the extreme case of power failure and reduce the load of the turbine, said MingYang.
MingYang’s Quant-Cloud team initially proposed a solution of applying an energy storage system to a wind turbine in a typhoon area to ensure safety during a grid outage.
Compared with a diesel generator, the energy storage system is a cleaner, safer alternative, MingYang said.
Quant-Cloud’s technology also deploys ‘big data’ to support the turbine to track wind direction changing in real time when the grid is cut off during a typhoon, to reduce the impact of extreme winds blowing against the nacelle.
