Summary of Content

-2 This module examines electrical power systems technology. An understanding of power plant systems, power -3 components and their application will be developed. Special emphasis on the interaction and integration of plant is given. The student will apply modern analytical modelling techniques to evaluate the operation and performance of a power system. Commissioning, maintenance, environmental and safety issues will be covered.

Syllabus

-4 The taught syllabus covers the following areas: Overview of interconnected power system: General requirements of power system, description of plant (generators, lines, cables, transformers, switches, reactors, motors, protection devices etc.), power (real and reactive), voltage, current and their relationship, integration and interconnection of system. Modelling of Power System: Line diagrams, per-unit system, equivalent circuits for rotating and static plant, introduction to application of models for fault, load, stability and protection studies. Load Flows: Radial and ring feeder load flow calculations, interconnected system load flow analysis, computer-aided analysis. Fault Studies: Types of faults (short circuit, open circuit, balanced and unbalanced), plant representation, symmetrical components, influence of reactors and transformers, fault injection from generators and motors, computer methods. Protection: Function of protection system, design/selection criteria of protection systems, components of protection systems, zones of protection, protection schemes, primary and backup protection, protection of transmission lines/transformers/generators. Stability: Instability in power systems, swing equation, machine steady-state and transient stability, equal-area criteria, computer aided models. Power System Control: Frequency, voltage and power control, Load Frequency Control (LFC), Governors, Automatic Voltage Regulator (AVR), VAr generation, static Var compensators, and Tap-changes.

Learning Outcomes

On completion of this module the student should be able to:Demonstrate an understanding of the concepts and operation of electrical power systems and plant items. Analyse a power system, including the application of appropriate computer-based tools, to determine fault level, load flow, and stability. Critically evaluate the performance of a power system. Outline and critically evaluate methods of controlling a power system. Design and evaluate a range of protection schemes. Outline appropriate commissioning and maintenance strategies for a selected item of plant including safety requirements.
