BREIF DESCRIPTION OF THE UNIT

Power System Plant:

• Overhead Lines: basic design, air-gap clearances, conductor electro-mechanical aspects, thermal rating, current rating, insulation design, environmental aspects including EMFs, conductor vibrations, and lightning protection.
• Power Cables: basic design, cable ducting, installation and lay formation, cable materials and electrical parameters, thermal rating calculations.
• Switchgear: types of switchgear, circuit breaker technologies, interruption media, characteristics of an electric arc, high and low resistance interruption methods, transient recovery voltage.
• Transformers: structure and functions of basic components, volts per turn calculation, tap changers, oil/cellulose insulation materials.

Power System Analysis:

• AC circuits: complex impedance, phasors, real and reactive power, and power factor.
• Three-phase systems: delta and wye connections, line-line and line-neutral quantities, instantaneous and complex power.
• Per-unit calculations for single and three-phase circuits: calculating different bases, converting between bases, equivalent circuits and one-line diagrams.
• Review of the main electricity generation technologies used in modern power systems and the nature and types of demand.
• Power flow calculation in simple two-bus system: transmission of real and reactive power, calculation of losses, voltage drop and maximum power transfer. Calculation of symmetrical fault currents.

On successful completion of the course, a student will be able to:

ILO 1: Describe the function, structure and design of the main power system components.

ILO 2: Explain the ageing, degradation and failure mechanisms of power system components.

ILO 3: Calculate design and operating parameters of power system components.

ILO 4: Design a simple electrical network and justify the selection of power system components.

ILO 5: Describe methods for generation of electrical energy in a modern power system and the nature and types of demand.

ILO 6: Analyse single-phase and balanced three-phase AC circuits using phasor diagrams and complex impedance.

ILO 7: Calculate the transfer of active and reactive power in two-bus AC power networks using complex power.

ILO 8: Analyse power networks using single-line diagrams and per unit parameters to determine operating conditions and fault currents.

ILO 9: Measure and analyse voltage, current and power in AC circuits and reconcile measurements with theoretical predictions.
