摘　　要：针对现有电能采集系统存在测量精度不够、软硬件设计复杂、环境受限和成本高等问题,设计了一种基于无线传感器网络的光伏逆变器电压实时监测系统,实现电网电压的多节点实时传输、测量和显示。系统以STM32为主控芯片,结合电能计量芯片和Zigbee技术实现电网电压信号的实时传输和监测,并通过上位机系统实现了多节点电压的实时采集、显示和数据处理。测试结果表明,各节点采集获得的基波三相电压均达到100 V以上,具有实时性、准确性和稳定性。Due to the problems of insufficient measurement accuracy,complex software and hardware design,inapplicable environment and high cost for the previous electric energy acquisition system,a photovoltaic inverter voltage real-time monitoring system based on the wireless sensor network technology was designed,which is aimed to realize real-time measurement and display of power grid power signals.STM32 was used as the main control chip,combined with electric energy metering chip and Zigbee technology to realize the real-time monitoring of grid voltage,and real-time acquisition.The transmission,display and data processing of multi-node voltage can be realized through the host computer system.The test results show that the acquired fundamental three-phase voltage all reach more than 100V,and this system has the advantages of strong real-time,accuracy and stability.
