“…The IEC 61850 standards introduced the concept of multifunctional IEDs. The multifunctional protection IEDs for Main and Back-up Protections are assumed to have a MTBF of 100 years [7] (Z=1-1/100=0.99) and are connected in parallel. The resulting reliability for the protection function is 99.99% (X=0.9999), for an average downtime of 52.56 minutes.…”

The introduction of IEC61850 standards for substation automation requires the specification of the reliability and availability performance parameter. Presently, the methodology to calculate and verify the parameters is not readily available. This paper proposed a methodology to calculate the parameters at device level, bay level and substation level. The paper will propose suitable monitoring and evaluation of those parameters for future improvement.

“…Assuming that the Station Control IED and the Local Control IED has a protection grade reliability of MTBF = 300 years [7], its availability is 99.67% (C=1-1/300=0.9967). Therefore, the overall Station Automated Control System's availability may be calculated and found as 99.24% (SACS= C*S*C*Y = 0.9924).…”

“…In order for the protection scheme to be successful it is important to carry out the following specifications: Selectivity, Stability, Sensitivity, and Speed. To meet all of the above requirements protection must be reliable, meaning that the protection scheme must trip when called up to do so (dependability) and it must not trip when it's not supposed to (security) [2][3][4].…”

-This paper focuses on the reverse blocking busbar protection scheme with aim to improve the speed of its operation and at the same time to increase operational reliability, flexibility and stability of the protection during external and internal faults by implementation of the extended functionality provided by the IEC61850 standard-based protective Intelligent Electronic Devices (IEDs). The practical implementation of the scheme by the use of IEC 61850 standard communication protocol is investigated. The proposed scheme is designed for a radial type of a distribution network and is modeled and simulated in the DigSILENT software environment for various faults on the busbar and its outgoing feeders. A laboratory test bench is built using three ABB IEDs 670 series that are compliant with the IEC 61850 standard, CMC 356 Omicron test injection device, PC, MOXA switch, and a DC power supplier. Two types of the reverse blocking signals between the IEDs in the test bench are considered: hard wired and Ethernet communication by using IEC 61850 standard GOOSE messages. Comparative experimental study of the operational trip response speeds of the two implementations for various traffic conditions of the communication network shows that the performance of the protection scheme for the case of Ethernet IEC 61850 standard-based communication is better.

“…In real substations, IEC61850 performs only a limited protective operations, but the main time-critical protections remain unchanged [2], [3]. As protection tasks are mission-critical, they must be executed in a timely and reliable manner [4]. In fault detection, protection devices trigger their output relay or send a high-speed peer-to-peer communications message to other IEDs in order to trip a breaker or initiate some other control and protective functions [5], [1].…”

“…Thus, the network designer must consider practical implementation issues, such as latency and speed of various messages and data that should be delivered to the intended recipients. Also, a designer should evaluate multiple possible designs and topologies that may meet the required specifications [4]. More importantly, the failure of an element or a connection may cause an undesirable delay or critical interruption in protection that seriously endangers the power grid's reliability and security [6].…”

This paper deals with stochastic latency in modern substation automation systems based on IEC61850. In order to meet the real-time requirements of mission-critical protection functions, latency evaluations are necessary to assess the expected performance level. A thoroughly-analyzed system under various contingencies ascertains that the communications design architecture is sufficiently fast and reliable. The presented methodology is demonstrated via a case study related to antiislanding protection of a power plant. The base case latency and stochastic latency were calculated and compared. This investigation reveals that a failure in the communications network can compromise the performance of the protection function without proper mitigation strategies such as utilizing devices with higher reliability, considering redundant parts, equipping network devices with monitoring and indication systems, and deploying GOOSE as opposed to ARQ.
