A power system always contains parametric uncertainties. In the design of a controller the uncertainties have to be considered. Otherwise, if the real plant differs from the assumed plant model, a controller, designed based on classical controller design approaches, may not ensure the stability of the overall system. In this paper design of robust control for the UPFC controllers including powe...

There are several problems existing in the direct starting of asynchronous motor such as large current, reactive power absorption from network side and weak interference-resistance, etc. Aiming at this, a comprehensive energy-saving optimization model for voltage regulation based on static synchronous compensator (STATCOM) is put forward. By analyzing working principle operation performance reg...

Abstract Traditional on-load tap charger (OLTC) transformer use mechanical switch or anti-parallel thyristor as changers. By changing the position of chargers, transformation ratio is changed, so to achieve discrete step voltage regulation function. In this paper a novel Flexible On-Load Voltage Regulator (Flexible OLVR) proposed, which integrated design Power Electronic Converter (PEC) and OLT...

This paper investigates performance of Fuzzy Supervisory Controller (FSC) in control of power converters. A FSC module is added to conventional narrow bandwidth voltage regulator in Power Factor Corrected (PFC), Voltage Source Converter (VSC) to improve DC bus voltage regulation. PFC converter is selected for this work as conventional design of the PFC converter requires narrow bandwidth DC bus...

The present work studies the modelling and PID controller tuning aspects of an automatic voltage regulator. is tuned using a hybrid optimization algorithm. This paper tunes BF-PSO Simulation results comparative analysis have been provided to validate Time-domain as well frequency domain has carried out. In order keep at terminals, VAR fixed set operational parameters. Different electrical devic...

By combining the field-weakening control principle of a new axial flux-switching permanent-magnet motor (AFFSSPM) with the space vector pulse width modulation (SVPWM) and maximum torque per voltage (MTPV) control principle, a novel field-weakening control strategy for AFFSSPM is proposed in this paper. In the first stage of the field-weakening, the difference between the reference voltage updat...
