Aims |
|
To give students a generalised view of the structure and operation of a modern power system. To develop the ability to analyse the steady-state and transient performance of an integrated power system, and control and stable operation of the power system concerning rotro-angle, voltage and frequency stability power flow and economic operation, and dynmic and control of power system. To introduce the basic principles of fault analysis and electrical safety regulations. To familiarise students with some basic concepts of power electronics and to provide them with the tools to design some basic circuits. To understand the principles of operation of power converters. To show how power electronics and machines are complementary components of drive or generating systems, through examples of practical applications. |

Learning Outcomes |
|
(LO1) An advanced understanding of the nature of the load on a power system and the way in which power is supplied by generators and transmitted to consumers. A clear understanding of how synchronous generators (alternators) interact with a power system in both normal and fault conditions. Knowledge of how these generators are interconnected by the high-voltage transmission grid. Advanced knowledge of complex power flow in a network. |
|
(LO2) An understanding of the matrix analysis of the network and load flow analysis. Good command of the per-unit system in the analysis of large power systems. A clear understanding of the consequences of different faults on transmission and distribution networks. Good awareness of general electrical safety issues. Advanced knowledge of various applications of power electronics in power systems and renewable energy. |
|
(LO3) A deep understanding of power system stability problems, analysis method and how to use control devices to maintain and improve the stability. |
|
(S1) Discipline specific practical skills, such as experience in analysis and design of power systems employing a broad range of industrial related engineering tools (e.g. power circle diagram and equal area stability criterion), and utilisation of different control devices in power transmission grid to improve the stability。 |
|
(S2) Independent learning, problem solving and design skills applied to power systems modelling, analysis and dynamic performance. |
|
(S3) Application of numerical methods to solve power flow problems, economic dispatch and stability assessment. |
|
(S4) Ability to produce clear, structured written work including simulation results. |
|
(S5) Use of Matlab/Simulink for power system analysis and control. |
