基于ADE7758的分布式光伏电能计量装置

Distributed Photovoltaic Energy Metering Device Based on ADE7758

针对目前屋顶分布式光伏发电系统中电能计量数据更新速度慢、观察不直观导致用户不能及时了解光伏发电量和补贴量的问题,基于ADE7758电能计量芯片设计了一种分布式光伏电能计量装置,该装置能够实现同时计量光伏发电侧和用户用电侧的电能流向和电能数值,计算光伏发电量和补贴量,并以短信发送给指定手机的功能。实验结果证明,该装置能够实现光伏发电量、用户使用量的精确测量,并能实现电量信息短信发送。

Aiming at the problem that the user cannot understand the photovoltaic power generation amount and the subsidy amount in time because of that the update of current energy metering data in the roof distributed photovoltaic power generation system is slow and the observation is not intuitive.This paper designs a distributed photovoltaic energy metering device based on the ADE7758 energy metering chip.The device can simultaneously measure the photovoltaic generation side also the electric energy flow direction and electric energy value of user’s electric power side.The device also can calculate the photovoltaic power generation amount and the subsidy amount,and send the short message to the designated mobile phone.The experimental results show that the device can accurately measure the amount of photovoltaic power generation and user usage,and can realize the transmission of power information short messages.
