Power Quality Simulation using MATLAB

Conducting power quality simulations using MATLAB can yield highly detailed results for various analyses including harmonic assessment, imbalance detection, and voltage deviation evaluation. These simulations enable engineers to comprehensively understand different aspects of power quality and make more precise decisions in power system design and maintenance. For harmonic analysis, MATLAB implementations typically involve Fast Fourier Transform (FFT) algorithms to decompose signals into individual harmonic components, allowing engineers to quantify each harmonic's contribution and develop solutions through fundamental waveform modifications. Imbalance detection algorithms in MATLAB often utilize three-phase voltage measurement data and calculate imbalance factors using symmetrical component methods, helping engineers determine whether three-phase voltages are balanced and prevent power quality degradation from unbalanced loads. Voltage deviation assessment employs RMS calculation functions and statistical analysis tools to monitor voltage stability thresholds, enabling engineers to ensure optimal power system operation. The simulation results provide crucial data for maintaining grid stability and improving power delivery quality.
