摘要:
为了满足微电网中储能蓄电池健康状态监测需求,该文基于GPRS技术设计一种远程监测系统。设计主要以检测蓄电池内阻为主,该系统以处理器dsPIC30F6012为核心,控制DDS芯片AD9833产生正弦波信号,经过恒流源驱动作用到蓄电池回路,再通过差分放大、带通滤波、有效值转换等电路采集蓄电池和参考电阻两端得到的交流电压信号,进而计算出蓄电池内阻。处理器获得相关数据后与设定限值比较,当数据异常时通过GPRS通信远程上传至上位数据中心服务器,提醒工作人员注意并进行相应处理,以提高微电网中储能装置运行的稳定性、可靠性。该系统设计简单、易于实现,具有一定的工程应用参考价值。
Abstract:
In order to meet the needs of energy storage battery health monitoring in the microgrid, a remote monitoring system is designed based on GPRS technology. The design mainly focuses on detecting the internal resistance of the battery. The system uses the processor dsPIC30F6012 as the core to control the DDS chip AD9833 to generate a sine wave signal, which is driven by a constant current source to the battery loop, and then through differential amplification, band-pass filtering, effective value conversion, etc. The circuit collects the AC voltage signal obtained at both ends of the battery and the reference resistor, and then calculates the internal resistance of the battery. The processor obtains the relevant data and compares it with the set limit value. When the data is abnormal, it is uploaded to the upper data center server via GPRS communication to remind the staff to pay attention and carry out corresponding processing to improve the stability of the energy storage device in the microgrid. The system design is simple, easy to implement, and has certain engineering application reference value.
