An Efficient Phase-Locked Loop for Distorted Three-Phase Systems

This paper proposed an efficient phase-locked loop (PLL) that features zero steady-state error of phase and frequency under voltage sag, phase jump, harmonics, DC offsets and step-and ramp-changed frequency. The PLL includes the sliding Goertzel discrete Fourier transform (SGDFT) filter-based fundamental positive sequence component separator (FPSCS), the synchronousreference-frame PLL (SRF-PLL)...

Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

Three Phase Power Flow for Distribution Systems with Dispersed Generation

This paper describes the development of a three phase distribution system power flow program. The program is developed without any radial topology assumptions and thus can be used to solve both radial as well as meshed networks without any restrictions. Distributed generation, any combination of different types of loads including constant power, constant current and constant impedance with floa...

Quality Power Provider Operating in Distorted and Unbalanced Three- phase Supply Condition

The quality of voltage and current delivered by the power utilities has become a major concern of the modern industries. The common power quality problems are voltage sag, voltage imbalance, transients, interruptions and harmonics. The two major power quality disturbances are voltage sag and harmonic distortion. In this paper, a Quality Power Provider (QPP) based on voltage source inverter is m...

Numerical modeling of three-phase flow through a Venturi meter using the LSSVM algorithm

One of the challenging problems in the Oil & Gas industry is accurate and reliable multiphase flow rate measurement in a three-phase flow. Application of methods with minimized uncertainty is required in the industry. Previous developed correlations for two-phase flow are complex and not capable of three-phase flow. Hence phase behavior identification in different conditions to designing and mo...
