  • To analyse the given system using SimPowerSystems blockset of MATLAB
  • To calculate the voltages and currents at various nodes (buses) and elements (branches) of given system

Introduction:

SimPowerSystems is used to model power system and carry out various tedious calculations pertaining power systems. It is a comprehensive tool box which can perform various analysis for power system such as load flow, short circuit current calculations, steady-state analysis and transient stability analysis. In this experiment we will use the steady-state analysis of the "SimPowerSystems" to find out the current and voltages in various parts of the Below-mentioned single phase system (Single line diagram). You are to calculate the voltages and currents at various nodes (buses) and elements (branches) of this system using the SimPowerSystems blockset of MATLAB.

Procedure:

Open MATLAB and enter the command โ€œpowerlibโ€ at the command window, this will open the library of the "SimPowerSystems" blockset. Now to start the modeling of the circuit, create a new model file from the file menu. Follow the same steps described in Lab- 1 to model the given system as shown on the next page: Open the powergui by double-clicking on its icon. This will show various types of analysis available to you to perform on the circuit. Click on the โ€œSteady-State Voltages and Currentsโ€ This will open a new window in which all the steady state voltages and currents will be given. Now write down all the voltages and currents in the โ€œmeasured valueโ€ column of Table.
