Power Automation Communication Management Machine

With the further development of the national economy, the demand to improve the automation level of power system is greatly needed. In the whole power automation system, power communication plays an important role. As a part of power communication, the communications of the Integrated Electronic Devices( IEDS) in the field with the local supervisory and the remote management center is discussed in the paper. To realize this, design and implementation of Management Machine of Power Communication is set forth in the paper.Firstly, the present condition of the power communication is discussed. At the same time, the necessity of the paper, and the function of the Management Machine of Power Communication, Protocol conversion and Communication Management, are also presented. Secondly, the scheme of the Management Machine of Power Communication, whose hardware architecture is based on C32 Digital Signal Processor (DSP) and software is based on Real Time Operation System (RTOS), is discussed. And also the possibility of realization of the scheme is demonstrated. In the following parts, the detailed implementations of hardware and software, such as serial communication extension, the LCD's interface with DSP, RTOS module, Protocol Conversion module, etc. are presented. After that, the result of experiment and the corresponding analysis are given. At last some problem of the paper and some followed work which can be done are summarized.
