Basic theory of electric circuits.

Generally, the student will be able to: - Apply voltage and frequency control techniques to electric power systems. - Perform basic power system studies similar to those carried out by system operators. - Analyze the dynamic response of a power system. More specifically, the student will adquire the following capabilities: Recognize the agents of a power system involved in each control system. Select the appropriate devices to solve voltage problems in an electric grid and to explain how they work. Recognize the phenomena that can result in a voltage collapse. Explain in detail the primary, secondary and tertiary frequency control systems. Explain the load shedding and other load disconnection schemes in the peninsular power system. Explain the behavior of the frequency control systems after different incidents in the power grid. Select a power system analysis software tool depending on the type of study. Explain the nature of electro-mechanical oscillations in a power system after a severe perturbation. Analyze the results of a dynamic simulation such as the performed by the transmission system operators.
