摘要
指出了在配电网管理和配电自动化系统实施过程中 ,通信是最为棘手的事情之一 ,其设计的合理性直接影响了DMS/DA系统的成败 ,利用配电线载波技术具有诸多优点。对配电线载波技术进行了介绍 ,比较了其与传统的电力线载波的异同。根据其工作原理 ,分析了影响配电线载波通信质量的主要因素 ,提出了改善配电线载波通信质量的措施。同时 ,对配电线载波通信方式和其他配电网通信方式的对接作了简单的说明。通过分析可以看出配电线载波虽然还有不少有待解决的问题 ,但具有很好的竞争力 。
In distribution management system & dispatch automation system,the communication is one of the most important and difficult problems.The rationality of the communication system has direct effect on the actualization of DMS/DA.It introduces the application of distribution line carrier(DLC)and compares it with power line carrier(PLC).The main factors that have effects on the DLC are analyzed.The methods to improve the DLC qualities are discussed here.It is simply advised how to connect DLC with other communication system in DMS/DA.There exist many difficulties of this technology in DLC,but it can be well used widely in the DMS/DA.
