系统采用PLC智能开关为控制器,风流中CH4浓度、风速为控制变量,变频器作为执行装置对局部风机进行闭环控制;采用振动监测技术,采集局部风机的振动信号,进行分析处理判断局部风机运行状态。智能控制自诊断局部风机实际应用效果良好,可以实现风电闭锁、瓦斯电闭锁、故障保护、主备电磁启动器断电切换、自动调节风速等智能控制及风机故障的诊断分析,且节能减耗效果明显,达到节能近40%。
The system adopts PLC intelligent switch as the controller, CH4 concentration in the wind flow and wind speed as the control variable. The inverter acts as the executive device to control the local fan closed-loop. Vibration monitoring technology is adopted to collect the vibration signal of the local fan and analyze the local fan operation status. Intelligent control self-diagnosis local fan practical application of good effect, you can achieve the wind power lock, gas lock, fault protection, the main electromagnetic turn off power switch, automatic adjustment of wind speed and other intelligent control and fan fault diagnosis and analysis, and energy saving effect Obviously, nearly 40% energy saving.
