[Abstract]:In order to solve the problems of distribution management and power quality improvement on the low voltage side of large users, a power quality intelligent diagnostic instrument based on high grade double ATmega128L high speed AVR and Zigbee wireless communication protocol is designed, and its hardware interface circuit design is introduced in detail. The hardware program design and its application in improving power quality are verified by field test. Using the rich in-chip resources of ATmega128L and the peripheral expansion circuit, and the high-precision synchronous instantaneous sampling chip MAX125, the field signals are collected, calculated, analyzed, displayed in real time, stored and recorded by the SD card. Then the Zigbee wireless communication method is used to realize the timing upload of measurement data and the real-time analysis of power quality by the upper system software, so as to strengthen the power management of private line users, effectively improve the power quality, and achieve energy saving and consumption reduction. The instrument has the advantages of easy to carry, low cost, high measuring precision, strong anti-interference ability and easy to be popularized. It can effectively meet the demand of power quality management on the low-voltage side of large users of special line.
