| DESCRIPTION | This study-unit covers basic principles of electrical engineering applicable to electrical energy generation, distribution and utilisation. The content is divided into the following topics: - Three phase systems: Complex impedances; Active, reactive and apparent powers; 3-phase connections; Balanced and Unbalanced Operation and Single Line Diagrams. - Distribution Systems: MV System; Transformers, cables and switchgear; Fault Level Calculation; Earthing Systems and Network Code. - Load Assessment: Load classification and current demand calculation; Diversity; Electrical Machines, Power Electronic Devices and Power Factor. - Power Quality Basics: Voltage variations, sags and swells; Harmonics and Electromagnetic Compatibility. - Alternative Supplies: Standby Generators; UPS; Renewables; CHP Systems and Energy Storage. Study-unit Aims: - To provide fundamental understanding of electrical circuits, power generation, distribution, utilization quality. - To explain the assessment of electrical loads in domestic, commercial and industrial premises. - To explain the operation of alternative supplies applicable to domestic, commercial and industrial premises. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - Identify the connection of loads and specify the relevant complex impedance for the assumed system frequency. - Describe the operation of 3 phase systems for both balanced and unbalanced loads. - Draw single line diagrams of electrical distribution systems. - Describe the distribution of electrical energy and the operation of distribution equipment. - Identify different types of Earthing Systems in use in electrical distribution systems. - Classify different electrical loads in buildings and identify relevant diversity factors from relevant regulations. - Identify the salient characteristics of common electrical loads in domestic, commercial and industrial premises. - Explain the drawbacks of a low power factor. - Describe the effect of power quality issues on the operation of electrical equipment in buildings. - Identify alternative sources for buildings and list relative characteristics and utilization. 2. Skills: By the end of the study-unit the student will be able to: - Determine specified voltages, current and powers in balanced and unbalanced three phase systems. - Determine the fault current for specified single- and three- phase systems at specific points. - Determine the expected current demand and its quality of specified loads in domestic, commercial and industrial premises. - Identify and apply suitable diversity factors for specific electrical loads in the calculation of total current demand. - Justify the selection of components for the improvement of the power factor of a specific installation to reach a given target. - Explain relevant power quality issues in supply voltage and current waveforms pertaining to specific installations. - Calculate basic parameters relating to alternative sources for buildings.
