Development And Implementation Of Substation IED Base On IEC61850

IEC61850 is the International Organization for Standardization released the latest standards for substation automation system, Aimed at harmonization of current into one of the substation automation of various communication systems, improve system maintainability, openness and scalability, the promotion of electric power system network, information technology development. In this paper, IEC61850 series of standards in-depth analysis and research, introduced the main contents of the IEC61850 standard, the main technical characteristics, Substation Configuration Language (SCL) and other content, and to propose the standard understanding. OPNET network simulation software, analysis of the characteristics and application of the process bus and substation bus simulation. Analysis of network bandwidth, network load, exchange rate, the sampling frequency, CPU utilization and other factors and the relationship between delay and, based on experimental results of the hardware system design.
