摘　　要：介绍了一种基于CAN总线的风电场电能质量监测系统的设计方法,对风电场的风电机组、箱式变和开关柜的电压、电流、频率、谐波、闪变以及现场风向风速进行监测,并将数据经CAN总线上传到上位机进行处理、分析及显示。监测网络有4层结构,即数据采集层、数据处理层、数据传输层、用户层。该系统已在广东某风电场投入使用,获得良好效果。The design of the real-time power quality supervisory system based on the CAN bus for wind power plants is presented. This system supervises the voltage, the current, the frequency, the harmonic and the flicker of wind turbine generators, box type transformers and high-tension switchgears, moreover, the field wind speed and wind direction. And the data are transmitted by the CAN bus to top-layer computer to be managed. The supervisory system has four layers, namely, data acquisition station layer, data processing layer, data transport layer and user layer. This system is put into operation in a wind power plant in Guangdong and favorable effects is achieved.
