风机安全链电路分析及安全控制策略的探讨

Analysis on Safety Chain Circuit of Wind Turbine and Discussion on Safety Control Strategy

风机安全链是风机控制系统的核心控制电路,它实时监控涉及风机安全的各部分控制环节,是确保风机安全可靠稳定运行的重要保障。文章以MITA WP3100主控系统为例,从安全链的电源、安全链自锁回路、安全链触发、安全链复位等几个方面分析了风机安全链电路,对提高风机安全链电路的认识及故障处理有指导作用;对风机安全控制策略提出了改进思路。

Safety chain of the wind turbine is the core control circuit of the wind turbine control system. It can monitor all ports of wind turbine safety control links in real-time, can ensure the security, reliablity and stability of the wind turbine. Taking MITA WP3100 master control system as an example, the wind turbine safety chain circuit is analyzed from the power safety chain, safety chain self-locking circuit, safety chain trigger and safety chain reset, which has a guidance on raising awareness of the safety chain circuit and troubleshooting, and proposes improvement ideas on the safety control strategy of wind turbine.
