A pilot protection algorithm for TCSC compensated transmission line with accurate fault location capability
Ghorbani, Amir; Mehrjerdi, Hasan; Heydari, Hamed; Ghanimati, Saeed ( Elsevier , 2020 , Article)This paper introduces a communication-aided scheme to enhance the fault detection, and fault location calculation for a thyristor-controlled series capacitor (TCSC) compensated transmission lines. In the proposed method ... -
Accelerated distance protection for transmission lines based on accurate fault location
Ghorbani, Amir; Sanaye-Pasand, Majid; Mehrjerdi, Hasan ( Elsevier , 2021 , Article)The accelerated operation of distance relay is an important issue to improve the power system stability. The zone-1 of distance relay usually covers about 80% of the transmission line length with an instantaneous operation, ... -
Accurate fault location algorithm for shunt-compensated double circuit transmission lines using single end data
Ghorbani, Amir; Mehrjerdi, Hasan ( Elsevier , 2020 , Article)This paper introduces an accurate fault location algorithm for double-circuit transmission lines compensated by Static Var Compensator (SVC). The proposed algorithm is based on the negative-sequence circuit of the transmission ... -
Accurate fault location element for series compensated double-circuit transmission lines utilizing negative-sequence phasors
Nemati, Mojtaba; Bigdeli, Mehdi; Ghorbani, Amir; Mehrjerdi, Hasan ( Elsevier , 2021 , Article)Obtaining the accurate fault location in the series compensated double-circuit transmission lines (SCDCTL) is a challenge due to the presence of series compensator, fault resistance, and mutual the coupling between parallel ... -
Adaptive algorithm for transmission line protection in the presence of UPFC
Mehrjerdi, Hasan; Ghorbani, Amir ( Elsevier Ltd , 2017 , Article)The presence of flexible ac transmission system (FACTS) controllers in transmission lines causes mal-operation of distance relays. The series-shunt FACTS devices have larger influence on the performance of the relays compare ... -
Adaptive control strategy for velocity control of a linear switched reluctance motor
Masoudi, Siamak; Mehrjerdi, Hasan; Ghorbani, Amir ( Institution of Engineering and Technology , 2020 , Article)A new adaptive control strategy for a double-sided linear switched reluctance motor is proposed in this work. Switched reluctance motors inherently have non-linear dynamics that complicates their analysis and control. The ... -
An Accurate Non-Pilot Scheme for Accelerated Trip of Distance Relay Zone-2 Faults
Ghorbani, Amir; Mehrjerdi, Hasan; Sanaye-Pasand, Majid ( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)The delayed operation of distance relays zone-2 element for the faults at the end of the line is excessive. It reduces the fault clearing speed and therefore, is one of the main factors that can endanger power system ... -
Distance-differential protection of transmission lines connected to wind farms
Ghorbani, Amir; Mehrjerdi, Hasan; Al-Emadi, Nasser A. ( Elsevier Ltd , 2017 , Article)Distance relays are often used in the protection of the transmission lines connected to the wind farms. The distance relay using the transmission line impedance measurement identifies the type and location of the fault. ... -
High-speed auxiliary fault location element for distance relays in double-circuit lines
Mehrjerdi, Hasan; Ghorbani, Amir ( Elsevier , 2021 , Article)In multi-zone distance relays, zone-2 has an intentional time delay which is considered for the coordination among the other distance relays. This delay is unnecessary for faults that occur at the end of the protected line ... -
Negative-Sequence Network Based Fault Location Scheme for Double-Circuit Multi-Terminal Transmission Lines
Ghorbani, Amir; Mehrjerdi, Hasan ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)The fault resistance and infeeded currents from tapped transmission lines are the two main challenges to establish correct fault location estimation in multi-terminal transmission lines. Also, fault location estimation in ... -
New elevator system constructed by multi-translator linear switched reluctance motor with enhanced motion quality
Masoudi, Siamak; Mehrjerdi, Hasan; Ghorbani, Amir ( Institution of Engineering and Technology , 2020 , Article)In this work, a new elevator system created by a linear switched reluctance motor is presented. Unlike conventional linear motors, the proposed linear motor has more than one translator. Each phase in a translator generates ... -
Synchrophasor-based backup distance protection of multi-terminal transmission lines
Al-Emadi, Nasser A.; Ghorbani, Amir; Mehrjerdi, Hasan ( Institution of Engineering and Technology , 2016 , Article)The distance protection of multi-terminal transmission lines need to be redesigned due to possible changes in the backup protection emanating from probable infeed currents produced from tapped transmission lines. Furthermore, ...
