Research Of New Generation Inverter With Intelligent Monitoring System

With the strong requirement of digitization and automation in electrical power engineering, higher requests are made by modern power supply equipments, to better support on-site commission and network administration. In this dissertation, the realization of both hardware and software in the intellectualized monitoring system of an inverse power supply system are systemically researched.The monitoring module in inverse power supply equipment is system engineering, composed of four parts:local resource management, human-machine interface, inverter monitoring module and remote monitoring. The kernel of the monitoring system is micro processor STM32F103ZET cored with Cortex-M3, which can realize the coordinately controlling of mass peripherals, communicating with external equipments using standard communication interface like RS-232, RS-485, CAN bus and USB bus, etc., afford administer with big touch-panel LCD, and also realize remote monitoring base on SNMP protocols with the assist of W5100.In this paper, the basic principles, structure and classification of inverse power supply technology are firstly introduced, and then, the superiority of the system core STM32 is presented, then the general design plan of the system is formed based on project requirement. After the basic research, the detail implementation descriptions of intellectualized monitoring system hardware and software are taken presented, and complex resource management with OS-free environment is described, also implement reliable digital communication protocol under strong EMI. At last, system testing, result analysis and conclusions are detailed in this paper. All the researches in this thesis play an active part in further research.
