Design of Intelligent Power Grid Monitor System

To solve the problems existing in current electric parameters monitoring system, such as bulky, high expense, difficult maintain, a new power monitor system is designed. The load on the system voltage, current, power factor, harmonics and other parameters are collected by MAXQ3180 chip, and through the SPI bus, data can be collected and provided to the AT89S52 microcontroller to preserve and manipulate. At the same time, in order to achieve decentralized control and centralized management, use CAN bus to communicate with the upper management machine to exchange data, and realize accurate measurement of electrical parameters and intelligent management. The system has a broad prospect of application in Chinese smart grid construction, which is a simple structure Circuit, easy operation, accurate measurement, high performance characteristics and so on.
