基于IEC61850的变电站自动化系统可靠性评估
Reliability evaluation of substation automation system based on IEC61850
摘要
Abstract
The substation automation system based on IEC61850 standard supports free distribution of functions and its reliability is closely related to the distribution mode of its functions. The realization principles of functions' free distribution are introduced and the method of reliability evaluation of substation automation system is proposed based on IEC61850. The system's functions are deposed into the connection diagram of logical nodes based on IEC61850 which consists of logical nodes and logical connections. The fault rates of logical nodes and logical connections are calculated based on the fault rates of physical devices and physical connections, then using fault tree analysis method to calculate the availability of system's functions and using it as the reliability index of system. Finally, the interval interlock function is taken as an example to introduce the method and confirm its feasibility which provides guidance to improve the distribution mode of system's functions and enhance the reliability of system.关键词
