Power System Analysis Methods

SimPowerSystems provides system analysis tools that:

• Display steady-state voltage and currents
• Display and modify initial state values
• Perform load flows and machine initialization
• Display impedance vs. frequency measurements
• Generate a report of the steady-state calculations

Simulation of a long-distance transmission system through a rectifier and inverter, each with its own controller. The system is fed by a high-voltage DC power source. Click on image to see enlarged view.

The SimPowerSystems graphical user interface displays steady-state values of measured current and voltages and all state variables, including inductor currents and capacitor voltages.

The load flow computational engine computes initial currents of synchronous and asynchronous machines. This feature automatically writes the resulting initial currents into the parameters for the machines. You simply specify the values for voltage and power that you want to simulate in your circuit and then click a button to compute the load flow.

SimPowerSystems lets you analyze the electrical network topology and compute the equivalent state-space model of your circuit without running a simulation. You can link the state-space model to the LTI Viewer interface in the Control System Toolbox (available separately) to obtain time-domain and frequency-domain responses.

You can use the data analysis, visualization, and optimization capabilities of MATLAB® to analyze output data, automate parameter sweeps, and calibrate your model.
