多功能测风参数监测系统研究

Multifunctional monitoring system of wind parameters

为了实现对风电场区域风资源评估,设计了一种多功能测风参数监测系统,从高可靠性、强扩展性的角度出发,采用PLC作为核心,对监测系统的硬件连接、数据采集、监测界面进行了设计。监测系统具有用户管理、实时监测、趋势图、报表显示和报警信息等功能。该系统特点在于对电压信号、电流信号、Modbus协议信号等都能实现采集监测,有工控机、触摸屏两种监测方式,采用工业上通用的OPC Server,能兼容其他系统的数据信息。实验表明:该系统功能齐全,在就地和远程均能实现监测,具有良好的可靠性和监测效果。

Wind farm construction and operation are dependent on the weather service. In the early days of wind farms, the wind resources and meteorological conditions should be monitored in real time, and the regional wind resources should be assessed. In order to realize the regional wind resource assessment of wind farm, we designed a muhifunctional monitoring system of wind parameters. From the point of high reliability and strong expansibility, PLC is adopted as the core to design the hardware connection, data acquisition and monitoring interface. The monitoring system has the functions of user management, real-time monitoring, trend diagram, report display and alarm. The system is characterized by the acquisition of voltage and current signals, Modbus protocol signals with two monitoring methods of IPC and touch screen. The system uses the industry＇ s common OPC Server which is compatible with other systems of data information. Experiments show that： the system is fully functional, in both insitu and remote monitoring, and shows favorable reliability and monitoring effects.
