Training courses on the components and systems used in power system compensation and harmonic filtering can be provided on an individual or group level. These courses normally extend over two days and deliver specific, detailed knowledge on the products we offer and the tools needed to implement and use them.
Training is also provided on site and hands-on during installation and commissioning, where the focus is more on operation, maintenance, safety and life time management of equipment. Such training is normally tailored to suit the exact requirements of our clients.
A typical training course syllabus intended for power system design engineers can contain the following:
Introduction: The context of filters in the modern grid – Time and frequency domain analysis – Causes of harmonic distortion – Impact of harmonic sources on the network – Capacitor banks
Components of passive harmonic filters: High voltage capacitors and banks (construction, rating, standards, tests) – grounded or ungrounded – Air core reactors – Thermal design – Resistance of the reactor – Mechanical design – Acoustic design – Insulation design – Installation of a reactor – Occupational safety of reactors – Standards, tests and enquiry information – Resistors (construction, standards and enquiry information) – Related equipment (Instrument transformers, switchgear)
Harmonic measurements: Standard for measurement – Measurement guidelines – Errors due to instrument transformers – Verification of coincidence factors – Recording existing harmonic levels – Measurements during commissioning
Design: Analysis process (loads, networks) – filters (operation, types, applications) – Scenario management – Analysis for compliance – Design for reliability
Protection and control: Filter capacitor bank protection (Unbalance, bank configurations, settings, over current) – fuses – control
Use of simulation tools: DIgSILENT PowerFactory – Study requirements – Network description – PowerFactory building blocks- Scripting
