It will specifically put into context the fundamentals of the plant parameters e.g. overhead lines, cables, transformers. Lastly, the module will elaborate on some basic techno-economic principles related to power plant operation. |
| Learning Outcomes: |
Knowledge and understanding: 1. Identify the main components and features of a Power Plant and understand their combined principles of operation and interaction; 2. Thoroughly understand the fundamental mathematical principles of the system and critically correlate them with the design characteristics, specifications and ratings, where this is appropriate. 3. Appreciate the importance of the legislation and relevant standards and further, develop the ability to effectively utilizing the given information for design and testing purposes. |

| Course Content: |
A Power System Plant embraces all the equipment, including structural members that constitute a unit power source. The module aims to provide an introduction to the overall design of power plant systems, focusing both on the system and on the component design. It will consequently provide an overview of the manufacturing, operating and thermal aspects of systems and the decisions necessary to deduce an optimal power plant design. Therefore, this unit aims to put into context the fundamentals of the plant parameters, by specifically introducing the following concepts: (1) Overhead Transmission Lines: Design and Operation A basic overview of the various components which make up overhead lines will be given. Not all but most, rely on air as the key insulating medium and consequently the treatment of insulators will be presented. The unit will also introduce how the series inductance and shunt capacitance can be derived from first principles for a transmission line consisting of several conductors. (2) Underground Power Cables: Design and Operation An overview of the power cable components will be given as well as cable assemblies and examples of power cables designs. Furthermore, the electrical and thermal characteristics of power cables will be derived and analyzed. (3) Power Transformers: Design and Operation As the transformer is probably the most important and expensive element of the Power System Plant, special attention will be given to transformer construction principles, by describing and analyzing the magnetic core characteristics, the insulating materials and finally the winding structures and designs. The unit will also elaborate on transformer design - fundamentals as well as on properties of transformer’s insulation materials and liquid breakdown mechanisms. Transformer’s factory tests including open circuit and short circuit tests will be presented and analyzed in detail. (4) Technical and Economical Assessment of Power Systems In the light of the continuous increase on power system investment and energy costs, the stakeholders are attempting to strike a balance between capital/operating expenditures and systems’ losses. The module will introduce the concept of valid financial analysis and correlate it where applicable to fundamental load characteristics and definitions (e.g. load factor, loss load factor, peak responsibility factor etc.) |
