Task A. Building and Simulating a Simple Circuit
Modeling:A following simulation model of simple circuit was developed by using Simulink blocks.
Figure 1 A model of Circuit Simulation Results:The parameters of above circuit:V1=424.4kV, fn=60Hz, P 110e6/300 W (quality factor=300), QL 110e6 vars, Qc 0.
Figure 2 The magnitude of source voltage U1
Figure 3 The magnitude of load voltage U2 in different conditions of source voltage
Discussion: In this task we have explored the powerlib library and learned how to build a simple circuit from the powerlib library. From the simulation result, we can see that the load voltage wave has different configurations depends on source voltage amplitude, frequency and phase.

Discussion: In this section, we have done the computing the steady state voltages and currents using the graphical user interface of the Powergui block as well as analysis of an electrical circuit in the frequency domain. The result has shown that frequency has a certain correlation with impedance and phase.
