基于可编程器件的电能质量监测终端设计

The Power Quality Monitoring Terminal Based on Programmable Device

针对目前电能质量监测终端存在集成度低、硬件电路调试繁琐等问题,提出一种基于FPAA(Field Programmable Analog Array)技术和FPGA(Field Programmable Gate Array)技术的远程电能质量监测系统。通过FPAA和FPGA技术的结合提高系统的集成度,利用FPAA技术的可重构特性减低电路调试繁琐问题。系统实现了太阳能并网系统电能质量基本参数、谐波、三相不平衡等参数的实时监测,实验运行证明终端具有硬件电路调试简单、升级自由度大、布置方便、智能性高的优点。

To deal with problems such as low precision and cumbersome in hardware circuit debugging , a remote power quality monitoring system based FPAA and FPGA is proposed in this paper. The system im- proves the integration of the system by FPAA and FPGA, it also reduces the debugging problem of the circuit by the reconfigurable characteristics of FPAA. The system implements real-time measurement of the basic parameters of power quality in the micro-grid, such as harmonic, there-phase imbalance, voltage/current, power factor. The terminal is easy to be debugged and installed, which is proved by ex- perimental results.
