In this thesis I discuss the cooperation of the synchronous power generating unit with the power network. I examine three areas of the power generating unit’s operation:
• the permanent load-ability
• the U-Q regulating facility at the connection point
• and the transient stability.
The examinations need real data of the power generating unit and parameters of the network at the connection point. The data and the configuration of the network which were used to set up the computer-based model belong to Gönyű’s power generating unit.
In the first part of the thesis, I discuss the P-Q curve as the permanent load-ability of the power generating unit: its background theory, how to draw it “by hand” and by Excel Visual Basic’s macros.
In the second part of the thesis, I discuss the U-Q regulating facilities from the side of the power generating unit. Firstly I introduce the summary of an international specification then I show the regulating facilities of the model which was set up before and how those fit the international specification.
In the third part of the thesis, I do a Load Flow calculation to examine the operation of the network configuration with Digsilent PowerFactory program.
In the fourth part of the thesis, I discuss the power generating unit’s transient stability. Firstly, I introduce the requirements of the transient stability and the requirements for grid connection of the power generating unit. Secondly, I do transient simulations of the computer-based model with Digsilent PowerFactory program. Eventually I compare the results of the simulations with requirement of the international specification.
The fifth part is the summary of this thesis’s results.
