MSc Electrical Power Systems Engineering / Course details

Analysis And Control Of Power Electronics Systems:

• Piece-wise-linear modelling and numerical techniques for time-domain solution. Circuit simulation. State-space averaging, and small-signal linearization. Transfer function models.
• Lumped parameter modelling of transient and steady-state electrical, electronic, mechanical and thermal systems, application of state-variable systems.

Analysis and Control Of Large Networks:

• Formulation of the power flow problem from first principles: Problem set-up; Equations and variables; Bus classification (PQ, PV, slack); matrix-vector formulation.
• Solution techniques for the power flow problem: Newton-Raphson algorithms (basic principle in one-dimension); extension to the multi-dimensional case; load flow feasibility, convergence and ill-conditioning; exploitation of PQ decoupling), DC power flow.
• Control of real and reactive power flows: effects of tap changers and quadrature boosters; Frequency regulation techniques in large power networks.

Faults in large networks:

• Symmetrical fault calculations: Modelling of networks under fault; solution using basic circuit analysis; the concept of short-circuit level and its factors of influence; faults in large networks.
• Asymmetrical fault calculations: Synthesis and connections of sequence networks; solution of sequence networks by standard circuit analysis techniques; transformation back to the phase domain. 

The course unit aims to:

Revise and build on control systems analysis for electrical/mechanical systems and power networks.

The unit develops models for use in system integration studies. These include power electronic converters, machines, other actuators, mechanisms and thermal considerations.  

The unit will also develop and formulate techniques and models of power networks for use in steady state analysis. Different method for power flow will be developed and used as a basis for quasi-steady state regulation and control of systems based on power imbalance. The unit will also revise techniques for analysis of faulted power systems and apply these to larger networks to evaluate system performance.

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

ILO 1: Perform fault and power flow analysis using a variety of methods by selecting relevant data and appraise the suitability of different methods for hand and computer-based solutions.

ILO 2: Describe the models and control schemes used for frequency containment in interconnected power systems and perform frequency disturbance calculations.

ILO 3: Describe the main factors of modelling and tuning time domain systems as well as the impacts and interactions of these factors, with particular consideration of command tracking, robustness and noise rejection.

ILO 4: Create state-feedback models from system equations and design and tune appropriate controllers, and apply a variety of methods to analyse the performance of the resulting systems.
