Abstract
Aiming at the situation that a wind turbine surge accident occurs frequently in the initial stage of a thermal power plant. This paper analyzes the causes and phenomena of the surge event of the wind turbine
and propose the specific operation method when the accident is handled. Then
the primary air volume measurement equipment of the coal mill is modified and once. The optimization and adjustment of the wind control function completely solved the problem of a surge of the wind turbine and improved the safety and economy of the thermal power plant.
