| Abstract | The traditional way to evaluate the system reliability or a probability of failure in the system is to use one of two basic approaches, direct analytical techniques or stochastic simulation. The emerging concept of Smart Grid requires advanced automation solutions for distributed electricity production and distribution. The automation system must fill the performance, availability and reliability requirements, including a probability of failure level under the specified limits. IEC61850 is a recent standard for electrical substation automation and it is also extended to the communication between substations. It provides interoperability in substation automation systems (SAS) consisting of devices by different vendors. This paper discusses about the evaluation of system reliability and the probability of failure existing in one protection intelligent electronic devices (IED), the evaluation of the general protection function and the breaker failure protection (BFP) function for practical small transmission substation T1-1. Different practical configurations are considered. A sequential Monte Carlo method is used to simulate the reliability and probability of failure. Comparison between analytical and simulation results is made by increasing the number of trails. Our result indicates how much the redundant ring architecture increases the reliability compared to the cascaded architecture. Applied Monte Carlo simulation method is also a flexible solution that has the ability to change, expand input data and include different parameters without a need to change the underlying software. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
