“…1. Bearing in mind that the failure rate probability of E/E/PE systems is constant and follows exponential distribution during the cause of the system's useful life [2], [8], [15], [21], the state transitions of the system depicted in Fig. 2 is, therefore, stochastic [15], [52].…”

The introduction of IEC-61850 digital-based Substation Automation System (SAS) eases implementation of elaborate schemes; however, its reliability and availability continue to be investigated for executing mission-critical applications. Independent repairable multi-channel systems with voting capability such as ‘one-out-of-two’ tripping schemes are often used for critical safety-related functions because the individual scheme channels hardly ever fail simultaneously. The system configuration enables the scheme to self-reconfigure when a link failure occurs in one of the channels, as well as being repairable with no interruption to the overall mission. This paper reviews the reliability and availability of evaluation methods to highlight their advantages and disadvantages. Structure-function modelling, as well as Markov process incorporating Systems Thinking and Mathematical Expectation are used to model the reliability of IEC-61850 based SCN to demonstrate the shortcomings of combinatorial methods in the evaluation of mission-critical systems where diagnostic capabilities of the systems and imperfect repairs should be considered. It is evident from the results of the study that system diagnostic capability and repair efficiency cannot be ignored for mission-critical applications for the reason that the simplifying assumptions of combinatorial analysis methods greatly over-state the reliability and availability performance of the system as observed from the results.

“…Finally, Ali et al [9] propose a novel network topology for the process bus where the bay Ethernet switches are connected forming a ring network, while each IED is connected to two different Ethernet switches (with its own bay Ethernet switch and to the adjacent bay Ethernet switch). In this work, the reliability and the end-to-end (ETE) time-delay performance of the network topology proposal are compared with traditional topologies such as cascade, star, ring and starring.…”

In recent years, communication networks on modern power substations have grown both in size and complexity, demanding the highest levels of reliability. However, there is no unique criterion to define the structure of the topology in such networks, since in every substation the end user implements their own topology or the topology suggested by a vendor, according to IEC 61850 standard guidelines. This paper proposes a methodology, using integer linear programming, to solve the problem of generating a reliable network topology in a software-defined power substations context. The trustworthiness of the reached solution is evaluated using terminal reliability techniques, graph metrics, and end-to-end time delay performance. The obtained results confirm that the proposed network topology is highly reliable to be implemented in power substations, according to the network redundancy considerations proposed by the IEC 62439 standard, and the operation time requirements suggested by the on IEC 61850 standard. In addition, we present software defined networking-based solutions for loop-based topologies in the proposed network topology, which would be technically unfeasible using traditional network protocols. These solutions include algorithms to solve problems related to the broadcast traffic containment and the diffusion and reliability of the multicast traffic.

With the integration of Distributed Energy Resources (DERs) into the distribution networks, the Active Distribution Network Management is becoming quite challenging. The DERs are integrated into the distribution networks through distribution substations. For achieving greater control and ease of operation substations are being automated by employing substation communication network based on standardized communication. IEC 61850 standard has emerged as the most popular standard due to its object-oriented modeling and interoperability features. To ensure smooth and efficient operation of substation automation system, the performance requirements for intra substation communication needs to be evaluated. This paper presents modelling of data traffic in the substation according to IEC 61850 and provides validation through simulation as well as through experimental setup. In the experimental setup, a real bay is replicated in the laboratory for performance validation. The scheme has been validated for VLAN and priority tagging implementation with the obtained simulation results.INDEX TERMS Active distribution system (ADS), IEC 61850, substation communication network (SCN), GOOSE.
