摘　　要：针对传统无功补偿监测系统难以实时随负载的变化而进行快速精确调节尤其是在故障时存在无功监测的数据处理量大、无法实时判断并记录的问题,构建了一种基于现场总线和无线通信网络的动态无功补偿实时监测系统,即在分析传统无功补偿监测系统特点的基础上,探讨了基于现场总线的无线通信网络的实现形式,通过在虚拟仪器平台上将过程控制中的现场总线和实时操作系统相结合,采用无线专用网络和普通网络完成主从站和站级补偿节点间的通信。在实验室环境下对系统的测试结果表明,该系统监测灵活、高效,避免了数据的冗余处理,提升了大量无功监测数据的高吞吐量。An intelligent reactive power compensation system based on the process field bus and wireless communication networks is built to overcome the deficiencies of traditional power compensation system,which can satisfy the requirements of rapid and accurate adjustment when the load is changing.On the basis of the analysis of working principle of the traditional reactive power compensation system,this paper discusses the forms of wireless communication network based on filed bus,integrated the field bus and the real-time operating system on a virtual instrument platform.Simultaneously,wireless special networks and common networks are used to accomplish the communication between the master-slave station and the compensation nodes.Reactive power compensation monitoring system based on field bus in distribution networks is more flexible and efficient,avoiding redundant processing of data.It is particularly important that the system can determine and record massive data in real-time especially when the system fails.
