Elements of Electrical Power Networks

The course focuses on the analysis of the operation of power distribution networks, where we are facing challenges due to the connection of renewable energy sources and the electrification of transport and heating. 

Historical overview of the development of the power system, structure of modern power networks. Mathematical basis for network analysis, analysis of unbalanced systems. 

Electrical parameters of lines. Distributed parameters line model, Pi line model, three-phase line model for unbalanced conditions. Resistance, inductance, and capacitance of lines. 

Transformer equivalent circuit. Load equivalent circuit. 

Passive and active compensation devices in power networks. Basic calculation of passive compensator elements. Structure and operation of a voltage source converter. 

Operation of distribution networks. Renewable energy sources and their impact on the network. Smart grids. 

Mechanical parameters of overhead lines, calculation of the height of transmission line poles.

The student will acquire the knowledge of main elements and devices of electrical power networks and the basic knowledge of mathematical modelling and parameters of electrical power elements used in power systems analysis.
