General course objectives:
The purpose of the course is to equip the students with knowledge of operation, control, and automation of electrical power systems.
The course is divided into two parts. Part one deals mainly with power system operation including renewable energy and different power system control systems that is required to control active power, reactive power, voltage and frequency whilst keep the power system stable with renewable energy sources. In this part students will be shown how to simulate these different control systems using PowerFactory as well as how to use different tools in PowerFactory to check for system stability.
Part two deals with power system automation focusing on the different SCADA communication protocols, e.g IEC 608705-101 & 104, IEC 61850, GOOSE, etc., power system automation systems, e.g. SICAM PAS, and SCADA systems, e.g. SICAM SCC. The students will achieve knowledge about SCADA principles and their relation to power systems.
This background allows the students to analyse existing energy systems and evaluate trends towards intelligent systems and components, i.e. Digital Grid, Grid 4.0 & Smart Grid systems.
Learning objectives
A student who has met the objectives of the course will be able to:
Understand the principle and use of governor-, AVR- and PSS controllers in a power system and how to model them using PowerFactory
Understand how to test for transient stability during fault condition on a power system using PowerFactory
Understand oscillatory stability, how to determine the eigenvalues using PowerFactory and how a PSS controller can solve oscillatory problems in a power system
Understand frequency stability in a power system and how to simulate this using PowerFactory
Understand conventional and renewable energy power generation including PV, wind and energy storage and their models in PowerFactory
Understand the stability of the power system with renewable energy integration and the impact of the low inertia and how it can be mitigated by use of virtual inertia and virtual synchronous machines
Understand voltage stability in a power system and how to use PV & QV curves in PowerFactory to determine the level of voltage stability and the reactive power requirements of a power system
Understand the basic principles of contingency analysis and how to simulate this in a power system using PowerFactory
Understand the principles of economic dispatch, unit commitment, optimal power flow and the energy market
Understand the difference between the different SCADA protocols, e.g. IEC 60870-5-101/104, IEC 61850, Modbus, etc.
Understand the basic principles of substation automation using GOOSE and a power automation system, e.g. SICAM PAS and be able to implement basic automation using GOOSE messaging and CFC programming
Understand the basic principles of SCADA configuration ("programming"), event recording and alarm handling
