Simscape Power Systems overview in Simulink - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a Simscape Power Systems model.

Simulink

model = simscape.[1]('PowerSystemModel');

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using plural form 'PowerSystems' instead of 'PowerSystem'.

Confusing with 'ElectricalSystem' which is not a Simscape function.

The correct function to create a Simscape Power Systems model is simscape.PowerSystem.

medium

Complete the code to add a voltage source block to the model.

Simulink

voltageSource = addBlock(model, '[1]');

Drag options to blanks, or click blank then click option'

BCurrentSource

CCapacitor

DResistor

💡 Hint

Common Mistakes

Choosing 'CurrentSource' instead of 'VoltageSource'.

Selecting passive components like 'Resistor' or 'Capacitor'.

The voltage source block is named VoltageSource in Simscape Power Systems.

Fix the error in the code to connect two blocks in the model.

Simulink

connect([1], [2]);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using commas without specifying ports.

Not using dot notation for block ports.

Blocks are connected by specifying their ports, such as voltageSource.load and load.

4fill in blank

hard

Fill both blanks to create a load with resistance and connect it to the voltage source.

Simulink

load = addBlock(model, '[1]');
connect(voltageSource.[2], load);

Drag options to blanks, or click blank then click option'

AResistor

Bload

CloadPort

DCapacitor

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'Capacitor' instead of 'Resistor' for the load.

Using incorrect port names like 'loadPort'.

The load is a Resistor block, and the voltage source port to connect is load.

5fill in blank

hard

Fill all three blanks to simulate the model and plot the voltage over time.

Simulink

simResult = simulate([1]);
voltageData = simResult.[2];
plot(voltageData.[3], voltageData.values);

Drag options to blanks, or click blank then click option'

BVoltage

Ctime

DCurrent

💡 Hint

Common Mistakes

Using 'Current' instead of 'Voltage' for the signal.

Plotting against 'values' instead of 'time'.

We simulate the model, get the Voltage data, and plot it against time.
