Power Quality Management

What You Will Learn

• 1 Learn the fundamental concepts and terminology of power quality including disturbances, standards, and measurement units.
• 2 Understand voltage sags and interruptions: causes, effects, and characterization parameters like magnitude and duration.
• 3 Analyze harmonics and waveform distortion: sources, calculation of total harmonic distortion (THD), and resonance effects.
• 4 Explore transients and surges: types such as impulsive and oscillatory, origins from lightning and switching, and protection strategies.
• 5 Apply power factor correction and reactive power management: causes of low power factor, benefits of correction, and capacitor bank sizing.
• 6 Implement power quality monitoring techniques: selection of instruments, placement, and interpretation of trends and event data.
• 7 Evaluate mitigation equipment: passive and active filters, UPS systems, surge protectors, and voltage regulators.
• 8 Comprehend key standards and compliance requirements: IEEE 519, IEC 61000 series, EN 50160, and grid codes.
• 9 Assess power quality in renewable energy systems: impact of solar and wind on grid stability, harmonic injection, and islanding.
• 10 Conduct power quality auditing: systematic methodology, data analysis, reporting, and troubleshooting common issues.
