The Research Of The Telecontrol Realtime Data Transmits On IP Wideband Network

Based on the present application and development of electric power automation technology, computer technology and area optical fibre communication, this article elaborates the necessity of achieving network communications between area dispatching and automatic substation based on DL/T634. 5104-2002 protocal and its realization essentials. Taking a 110kv automatic substation in Yangquan Power-supply Branch as example, this article sets forth the concrete realization method. Meanwhile, the article expounds the advantage and prospect of achieving network communications between area dispatching and automatic substation by comparing with previously applied CDT protocal issued by electric power Ministry.
