国产某1.5MW双馈型风电机组安全链复位无效故障分析及改进

A Domestic 1.5MW Double-fed Wind Turbine Analysis and Improvement of Invalid Failure of Safety Chain Reset

风力发电机组安全系统也叫安全链,是由符合国际标准的逻辑控制模块和硬件开关节点组成。在风力发电机组控制系统中,安全链电路作为最高级别的保护,也是最后一道防线,其是否能够正常工作对机组的安全性、可靠性来说尤为重要。

The wind turbine safety system is also called the safety chain,which is composed of logic control modules and hardware switch nodes that comply with international standards.In the wind turbine control system,the safety chain circuit is the highest level of protection and the last line of defense.Whether it can work normally is particularly important to the safety and reliability of the unit.
