Simple distance protection scheme

WebbDistance protection is a mature protection mainly used in transmission systems . It is based on the observation that the protected line impedance is proportional to its length: monitoring changes in the impedance (e.g. by measuring locally voltage and current) thus enables the identification of a fault without any communication device. WebbThe selected protection function is an impedance relay that provides basic protection for phase and ground faults. It uses a mho characteristic, polarized with positive-sequence memory voltage [10]. A four-shot auto-recloser logic scheme is presented as well. The calculation of impedance is simple in the RTDS, using the
