Abstract: The dynamic processes of power systems represent a dangerous but fascinating problem and knowing them precisely in order to prevent or reduce their consequences is a real challenge for specialists. Due to their unpredictability, it is difficult to get them known and thus mathematical simulation is necessary. It is a very useful instrument, but it requires a very careful choice of the simplifying hypotheses and an experimental testing of the results. This is the topic of the lecture. It presents a mathematical simulation of a steam power plant connected to an electric network supplying a set of consumers. It simulates a dynamic insulation process of a large industrial consumer through its sudden disconnection from the power system. The evolution of the insulation is followed through until its post emergency stability state is reached. The results are then compared with those of an insulation of a large industrial consumer equipped with its own power source - The Integrated Iron and Steel Work- Hunedoara - Romania. The comparison has led to the validation of the mathematical simulation. It has become a very useful instrument for studying the dynamic regimes and the determination of critical states of power systems.
