Subject description

Prerequisits:

The prerequisite for the course is enrolment in the second year. The prerequisite for the oral exam is a positive assessment of tutorial report.

Content (Syllabus outline):

Introduction to power quality, basic terms and definitions, overview of power quality standards. Transient phenomena, long term voltage deviations, short term voltage deviations, voltage unbalance. Waveform distortions; dc components, harmonics, interharmonics. Voltage fluctuations – flicker. Voltage sags and interruptions. Supply interruption indices.

Measurements of power quality parameters, permanent monitoring systems. Modelling of parts of power networks and loads for power quality analysis; system impedance characteristics. Methods of sharing responsibility for power quality distortion between network and customer side. Spreading disturbances across the network.

Measures for power quality improvement.

Objectives and competences:

The student will acquire the knowledge of basic power quality terms and supply voltage characteristics and will also improve their knowledge of measurement performance, analysis of measurement results of power quality parameters, and possible measures to improve power quality.

Intended learning outcomes:

Knowledge and understanding:

Students will understand the importance of power quality for the operation of power networks and customer supply. Students will also learn about the main parameters of voltage quality and compensation methods.

Application:

Prerequisites for further study, and practical application of measurements and power quality analysis.

Reflection:

Understanding the connection between the quality of supply, compensation planning and consequences of poor quality of supply.

Transferable skills:

Knowledge of measurement procedure and analysis of measurement results is useful in the frame of various measurements.

Learning and teaching methods:

  • Lectures,
  • tutorials,
  • laboratory practice.
