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.

“…If the modified indices at all the load points satisfies the constraints (17) and (18) the procedure is terminated and final FOR for all the distributor segments are provided as targets to maintenance and repair crew. Otherwise again TCIP's are calculated for all the segments and another feeder section is selected for modification of failure rate/repair times.…”

This paper describes an algorithm for forced outage rate (FOR) allocation to each section of an electrical distribution system subject to satisfaction of reliability constraints at each load point. These constraints include threshold values of basic reliability indices, for example, failure rate, interruption duration and interruption duration per year at load points. Component improvement potential measure has been used for FOR allocation. Component with greatest magnitude of credible improvement potential (CIP) measure is selected for improving reliability performance. The approach adopted is a monovariable method where one component is selected for FOR allocation and in the next iteration another component is selected for FOR allocation based on the magnitude of CIP. The developed algorithm is implemented on sample radial distribution system.
