Analysis and methodology for measuring the IEC61850 GOOSE messages latency: Gaining interoperability testing

Abstract

IEC61850 standard provides new kind of solution and offers efficient performance within a substation automation system (SAS). This efficiency has been introduced by means of exchanging real-time information, reducing life-cycle costs and interoperability. Measuring the transferring messaging latency and interoperability testing within the Substation Automation System (SAS) are crucial tasks that require special efforts based on several modern hardware and software tools have to be used. Since, these tasks are an important issue that must be realized by Power Utilities within the design and implementation of the SAS process. Therefore, this paper provides the analysis and the methodology for measuring the transferring messaging latency of the Generic Object Oriented Substation Event (GOOSE) within the SAS. Successful measurements for the transferring GOOSE messages latency within different case study scenarios have been achieved in which that illustrate the Device under test (DUT)s are compliant with the IEC 61850 criteria. Moreover it proves the interoperability concept that the DUTs subscribe to the GOOSE messages from the third party Intelligent Electronic Devices (IED). Tasks have been implemented using a round trip time measuring method.

Enhancement of IEC 61850 AS using Vendor-Natural system tool

“…As a result from the above discussion and from the increased demand to overcome the lack and the limitation of the existing (IED, system) configuration tools [2][3][4][5][6][7][8][9][10] (based on the IEC61850 extending standardizing concept include the protection and setting level), a platform of simple network Vendor-Natural configuration tool had been invented in which that can be used to design and configure different vendors' instruments and systems. Vendor-Natural configuration tool provides an answer to a real end-user need.…”

“…However, those projects are trivial they facing some big challenges based on the configuration of the IEDs and the AS using different vendors' proprietary configuration tools to achieve a seamless communication system network among the multi-vendor IEDs. Moreover projects in [2][3][4][5][6][7][8][9] had been identified that the major challenges facing the implementation of the IEC 61850 standard within a multi-vendor IEDs and the most costly, efforts and consuming-time process are the configurations of the IEDs based on the existing AS configuration process in order to reach a smooth communication and gain the interoperability. They are commonly believed that the reasons for these challenges are the open nature of the IEC 61850 standard gives wide range of freedom for the vendors to operate with.…”

Analysis of GOOSE message and the engineering application for GOOSE message in the intelligent substation

“…The application of GOOSE in the process layer of the intelligent substation is mainly for the purpose of ‘protecting the trip’ and other important messages, which must be transmitted to the destination in time within the specified time. Therefore, it is of great significance to and it has a practical value to study and analyse GOOSE and SV messages in the IEC61850 standard environment [8–11].…”

Interoperability Performance Assessment of Multivendor IEC61850 Process Bus

“…Consequently, many utilities are not confident in the full adoption of the standards, and especial concern is given to the process bus. Numerous validation exercises have been conducted to assess the performance of SV and GOOSE on systems supplied by a single vendor [9]- [12], or a small group of collaborating vendors [13]- [15]; but limited interoperability results have been presented for complex systems that involve multiple devices from different vendors. An experimental approach is proposed in this paper, which assesses and analyses the interoperability performance of an IEC 61850 process bus architecture utilising devices supplied by four major vendors.…”
