IEC 61850 based substation automation systems simplify the design, installation and maintenance with significantly reduced cost. Its real-time, security and reliability are of concern and are vital important to the industry. This paper presents the development and application of an established platform for evaluating process bus applications. The evaluation platform consists of a number of GOOSE,...
A major challenge facing utilities today is the successful configuration and testing of multi-vendor protection schemes using the IEC 61850 standard. Even though the IEC 61850 standard allows for interoperability between different manufacturers' relays, the implementation of the communication protocol varies greatly from vendor to vendor. The standard does not mention how the IED should be configured...
Since IEC 61850[1] became the widely used standard for substation communication with a lot of implementations testing is an important issue. The standard in its current version covers some possibilities and approaches for testing in general and for measurements of performance. They will be described and analysed. According to the approach of IEC 61850 the IEDs (Intelligent Electronic Devices) contain...
This paper outlines the design challenges facing the protection and control systems required for offshore wind farms. In particular, the focus will be upon the integration of these systems and the distinct differences between the approaches taken for offshore compared to those of traditional onshore substation systems.
Testing IEC 61850 devices is a critical part of any substation automation scheme. Many IEDs have been installed and configured to provide status and control via GOOSE messages. IEDs can also be configured to listen to sampled value data. An important part of IEC 61850 data being transmitted can be the test and quality information. Real time digital simulation using a closed loop environment was done...
Standard communication protocols have been used for substation automation for many years. The applications are mainly on the station level communication to indicate alarms and events within a substation and make them visible to the operator. However the configuration and implementation of the protocols have differed widely between manufacturers leading to difficulties when attempting to support product...
For the Delayed Auto-Reclose (DAR) and Autoswitching (ASW) systems in Mesh Corner circuits, taking into consideration the desire to minimise the overall system cost by reducing hardwired connections and auxiliary relays, the advanced multifunctional numerical relays with GOOSE (Generic Object Oriented Sub-Station Event) Communication interface via UCA2 (Utility Communication Architecture) protocol...
