Improving ATC is important in the current deregulated environment of power systems. In this paper, ATC is computed using Continuous Power Flow (CPF) method considering line thermal limit and bus voltage limits. Flexible Alternating Current Transmission system (FACTS) can control magnitude of voltage, phase angle and circuit reactance and the load flow may be re-distributed to regulate bus volta...

Compensation is crucial in the inductive power transfer system to achieve load-independent constant voltage or current output, near-zero reactive power, higher design freedom, and zero-voltage switching of driver circuit. This article proposes a simple, comprehensive, innovative graphic methodology for compensation topology realize output at zero-phase-angle frequencies. Four types graphical mo...

In this article, a multi-objective planning is demonstrated for reactive power compensation in radial distribution networks with wind generation via unified power quality conditioner (UPQC). UPQC model, based on phase angle control (PAC), is used. In presented method, optimal locating of UPQC-PAC is done by simultaneous minimizing of objective functions such as: grid power loss, percentage of n...

An AC chopper controller with symmetrical Pulse-Width Modulation (PWM) is proposed to achieve better performance for a single-phase induction motor compared to phase-angle control line-commutated voltage controllers and integral-cycle control of thyristors. Forced commutated device IGBT controlled by a microcontroller was used in the AC chopper which has the advantages of simplicity, ability to...

Motor drive systems based on diode-rectifier are utilised in many industrial and commercial applications due to their cost-effectiveness simple topology. However, these diode rectifier-based can be affected by power quality harmonics distribution networks. Thus, this paper investigates the impact of grid voltage operation converters with three-phase rectifier using mathematical formulation curr...
