Abstract

Communication systems of intelligent electronic devices play a huge role in the performance of busbar protection schemes. They determine the effectiveness of the protection scheme in terms of detecting and isolating busbar faults. A literature survey has revealed that multiple proposed algorithms of busbar protection schemes have encountered a common problem of achieving interoperability between intelligent electronic devices produced by different vendors. This affects the performance of busbar protection schemes. This paper focuses on achieving interoperability between IEC 61850 standard-based multi-vendor intelligent electronic devices “SEL and ABB”. This improves the performance of busbar protection schemes between multi-vendor devices, and at the same time increases the operational reliability. The investigation is conducted using a current differential busbar protection algorithm. The study is performed by implementing hardware-in-the-loop (HIL) testing using a real-time digital simulator (RTDS). A laboratory-scale test bench is developed to achieve interoperability between the IEDs SEL-487B and REF615. A fault condition is simulated, and the behaviour of the protection scheme is analysed. The hardware-in-the-loop results demonstrate the benefit of the proposed technique.
