The Localization of the Wind Turbine Passive Spindle Brake Based on Mechanical Mechanics

Abstract:

Wind turbines typically run in harsh environments region, but the general requirements in the case of work unattended. Therefore, the brake system is a key component to protect the safe operation of wind turbines. When the wind turbine over speed occurs, overload or other abnormal conditions, the brake system needs to start immediately, so that the whole unit into the shutdown state to ensure crew safety. This article describes the role of wind turbine brake system, composition, operation principle, comparing the advantages and disadvantages of the most commonly used active and passive spindle brake doubly-fed wind turbine. Completion of a wind turbine import passive brake design, manufacturing localization, combined with wind turbine machine operating parameters, developed analytical test program brakes and the test results, and for the test questions are designed to improve.
