ABSTRACT: This paper presents the
dynamic simulation and testing to verify the smart substation solutions
designed for a brown field 110 kV retrofitting project. An IEC 61850 based
aotomation design, transitioning the conventional substation into a smart
substation, where existing current/voltage transformers remain in service, and
smart Field Apparatus Interface Units (FAIUs) are utilised to bridge the
conventional primary system to the IEC 61850 based secondary system. While
outdoor switchgears and field instrument transformers are equipped with FAIUs, MV
indoor switchgears are installed with IEDs mounted on the top. Direct
point-to-point connections serve as process buses, and a single PRP/RSTP LAN is
employed at station bus level. Extensive dynamic simulation and testing were
conducted in the Smart Substation Technologies Lab, and test results show the
smart substation performance meets and exceeds the substation reliability
requirement.
