【摘要】 智能配电网的建设,紧紧依赖于可靠的数据采集与监控系统的建立。在智能配电网的环境下,主站与子站间数据通信大幅增加,同时要求数据采集系统提供全面、实时的动态数据,而目前SCADA系统及PMU均无法满足此需求,为此提出一种将SCADA系统升级为动态SCADA的方法:通过引入新型采集终端动态RTU,从硬件和软件两个层面对SCADA系统进行改造,使其满足智能配电网动态信息采集的需求。在此基础上,搭建动态SCADA原型系统,详细研究其通信实现中存在的通信阻塞问题,提出非阻塞式IEC 104规约实现方法。最后在所搭建的动态SCADA原型系统中,对此方法进行压力测试,结果表明,该方法能够显著提高动态SCADA系统通信的可靠性。更多还原

【Abstract】 The development of smart distribution grid strongly depends on the establishment of reliable communication platform. Nowadays,communication between stations is increasing rapidly and real-time data of the whole network is required,which SCADA and WAMS could not provide. This paper proposed a method to upgrade SCADA into dynamic SCADA by installing a new equipment called dynamic RTU. On this basis,the paper built a prototype system and proposed an analysis of the traditional implementation of IEC104 protocol communication and pointed out its shortcoming. And implementation of the non-blocking 104 protocol communication using the non-blocking implementing method significantly improves communication performance in the dynamic SCADA.更多还原
