摘 要: 风电场电磁环境恶劣,其监测系统实时性强,监测数据多,受电磁干扰影响大。针对并网型风电场监测系统的实际运行,介绍了基于控制器局域网(CAN)总线的监测系统的结构特点,分析了影响风力发电机组正常运行的各种电磁干扰及其危害。通过对防雷措施、数据采集装置、CAN总线数据传输的电磁兼容、机壳设计以及风电场特殊接地等部分的具体分析,提出了改善监测系统和设备电磁兼容性能的具体方法。 Monitoring systems of wind farms located in severe electromagnetic environment have strong real-time and multi-channel, and may be interfered with EMI seriously. To counter the specializations of monitoring system base on CAN bus of grid-connected wind farm, the structure of system is introduced and different electromagnetic interferences as well as their damage infrueneing normal operation of wind turbine are analyzed. By analyzing lightning protection, DAS, EMC of CAN bus transmission, case design and wind farms special grounding ways, some effective methods are put forward to improve systems and equipments electromagnetic compatibility.
