The main topic of my thesis is the creation process of a dynamic model that is able to generate
schedules for each railway traction transformer. Besides, I describe the specialities of the
operation of the electricity market, with particular attention to the relation between the
trader and the consumer.
The topicality of my research is given by the situation established by a new contract between
the Hungarian Railways and electricity traders. According to this contract, 3 different traders
supply electricity to the Hungarian Railways in 6 districts. Therefore, the price of the balancing
energy appears to three different traders.
My research was carried out in the following steps. First, I elaborated the modeling with regard
to a transformer district. The base of the method followed in my thesis as well as the starting
data were available due to a former investigation at the Department of Electrical Power
Engineering. During the processing of data, I made use of the MATLAB and Excel applications.
As a following step, I compared the estimations given by the model to the data recorded by
power meters of the engines and the transformer.
As a conclusion, it can be stated that the dynamic model predicts the expected energy
consumption with an acceptable approximation. However, the model can be improved in
several different ways, aiming at more precise approximation, as well as the extension of the
applicability of the model.
