No ethical clearance was required for the study, HDC approved the study to proceed.

The Datasets are the configuration of the nine-bus system network in RSCAD, the design of different control logic. Power system data used in the study of the design and development of the Multi-Vendor Based Transformer Protection Scheme for Transmission Network. In order to test this protection, a lab-scale test bench is set up at the CPUT CSAEMS laboratory utilizing a transformer protection relay and CMS omicron injection device.

This research aims to develop a transformer current differential protection scheme, investigate the IEC61850 standard-based interoperability challenges between the Intelligent Electronic Devices produced by different vendors (Multi-Vendor), and propose solutions for improving communication between these devices. Using system simulation software tools, researchers employ IEEE systems to implement and test creative ideas and concepts. The transmission system of IEEE 9-Bus is selected as a case study, and IEEE 9 has been modified at bus 6 with sub-transmission and distribution with two parallel transformers. The study utilized the parallel transformers that have a 110/22kV with a 56MVA protected by two IEDs (SEL-487E and ALSTOM MiCOM-P645 relays) differential protection, with a speed of fewer than 20 msec responding to the faults and has communication capabilities of the IEC 61850 standard.

The test plan aims to evaluate the performance of parallel transformer differential protection schemes through hardware-in-the-loop (HIL) testing. The methodology involves implementing HIL testing with the RTDS simulator, utilizing MiCOM-P645 and SEL-487E relays for protection scheme testing, and subjecting the system to various fault scenarios and abnormal operating conditions for in-depth analysis. The rationale behind this plan is based on several key factors.
