Advanced Phase Selection for Severe Line Protection Requirements

ABSTRACT This paper describes a new phase selector that operates reliably during many unfavorable conditions, such as high fault resistance, high load flow, power swing, Current Transformer (CT) saturation, converter-based generation, weak infeed. The phase selector is based on the angular relationship between the sequence current components and sequence voltage components. The use of voltages and currents is dynamically selected. [...]
