风力发电机组并网运行时,会影响电网的电能质量,如电压偏差、电压波动、瞬变、闪变、谐波、频率、三相电压不平衡等,严重时会对电网的安全稳定性造成危害。因此应用传感器对风力发电各项参数实时进行数据采集,对监测风力发电的安全方面十分必要。本文利用无线通信网络将采集的信息发送给远程控制端的PC机或者管理者的手机,由此可以实现对风力发电状态数据的实时监控与故障诊断功能,用户可以远程实时了解到当前的发电状态,并能够及时预测到故障信息,从而提高了风力发电系统的安全性和长期运行的稳定性。
When the wind turbine is running on the grid, the power quality of the grid will be affected, such as voltage deviation, voltage fluctuation, transient, flicker, harmonics, frequency, unbalanced three-phase voltage and the like, which may seriously affect the safety and stability of the grid harm. Therefore, the application of sensors on the wind power parameters of real-time data collection, monitoring the safety of wind power is necessary. This paper uses the wireless communication network to send the collected information to the remote control terminal PC or manager’s mobile phone, which can achieve real-time monitoring and fault diagnosis of wind power status data, the user can remotely understand the real-time current power generation status, And can predict the fault information in time, thereby improving the safety of wind power generation system and the stability of long-term operation.
