HV grid model in PSCAD
 Tomšů, Vojtěch ; Ptáček, Michal (referee) ; Kopička, Marek (advisor)
This thesis deals with the issue of computer modelling and electroenergetic calculations. The first part focuses on the description of the PSCAD program and selected competitive software. There are listed main characteristics, usage and subsequently the overall comparison of the programs with potential use in electroenergetic industry. It also lists the basics of PSCAD and description of its working environment. Another section deals with the calculation of parameters of overhead lines, transmision lines substitute with pi-section and the process of pi-section phasor diagram construction. In the next part, there is a model of HV grid in the form of pi-section. As reference values for simulation were used values from exercise of the subject Distribution of electric energy. Output values obtained from the simulation in PSCAD were used to create a phasor diagram in Matlab. The last part focuses on the issue of calculating the natural power, cascade and parallel sections sorting and a simple case of three-phase fault.
