Laboratory of Electrical Power Engineering 1

Course Description

The course is organized in three laboratory blocks. In the first block students should get acquainted with Power Plant Simulator AES 2000 (manufactory is Applied Educational Systems, Inc.), to understand the dynamic behavior of the thermal power plant in the different operation conditions and interactions between power plant and power system. In addition they should be able to calculate thermal efficiency of the steam (Rankine) and gas (Bryton) power conversion cycles in thermal power plants, basic flow relationships in hydro and wind power plants, power production in nuclear reactor core and heat transfer in electric power network components. In the second block by using the software package Matlab ? Simulink (manufactory is MathWorks, Inc.) students be able to develop dynamic model of electric power system for investigations of frequency variations after the disturbances. And in the third block students should get acquainted with power systems environment, be able model power system elements and system.

General Competencies

Students will be able to recognize main problems in power plant control. They will get practical experience with state estimation, power flow, short circuit and security analyses. Students will be able to develop dynamic models of electric power system. Students will be able to model main components of thermal, nuclear, hydro and wind power plants to check basic power conversion characterisitics using modern state of the art computer codes and models. Student will have basic capabilities to calculate heat production and dissipation in electric power system components.
