Power Quality Engineering and Active Filters: Harmonics, Flicker and Standards

The Power Quality Engineering and Active Filters programme gives you a solid, applicable foundation across industrial, commercial, utility and renewable-energy settings (harmonics, flicker, voltage sags, unbalance, passive and active filtering, compensation devices, monitoring and compliance). The training combines power system analysis, modelling and simulation, real-time control implementation and measurement per IEC 61000-4-30, linking diagnosis, mitigation design and verification so you can make faster decisions and demonstrate compliance with grid and equipment standards.

The approach combines technical rigour with business criteria to deliver efficient, safe and scalable solutions: from the power quality audit and harmonic study to filter sizing, commissioning tests and compliance reporting. On completion, you will be able to lead end-to-end power quality projects, design and tune shunt active power filters, hybrid filters and related compensators, use advanced tools (MATLAB/Simulink, PSCAD, DIgSILENT PowerFactory, DSP/FPGA platforms) and coordinate multidisciplinary teams in demanding environments.

Target keywords (used naturally in the text): power quality, active power filter, harmonics, flicker, IEEE 519, EN 50160, IEC 61000-4-30, THD, shunt active filter, STATCOM, power quality monitoring, grid compliance.
