### Industrial System Dynamics

Data is displayed for academic year: 2023./2024.

#### Course Description

Configurations of industrial power systems and their voltage levels. System components: transformers, generators, motors, power converters, filters, compensation and protection devices. Mathematical models of components and systems. Operation of an industrial system by itself or connected to the power system. Drive dynamics with and without a power converter. Total harmonic distortion of a system and filter’s parameters determination. Reactive power compensation systems and their behavior in transient and steady states. Power supply’s stability, fault and transient states. Interaction between the power system and an industrial plant’s power system in case of sudden load changes. Overvoltages of industrial power supply system caused by switching on and off different components in the system.
