Revision as of 15:23, 26 September 2019
| Visual Cue | Narration |
| Slide Number 1 | Welcome to the Spoken Tutorial on Simulation of a SMIB using OpenIPSL. |
| Slide Number 2
|
In this tutorial, we will learn:* How to simulate a controlled SMIB system
|
| Slide Number 3
|
To record this tutorial, I am using* OpenModelica Version 1.12.0 and
Also use the latest version of OpenIPSL to avoid compatibility issues. I am using OpenIPSL version 1.5.0.
|
| Slide Number 4
Prerequisites
|
To follow this tutorial, you should have knowledge of:* Power systems
For relevant OpenModelica tutorials, please visit our website. |
| Slide Number 5Prerequisites | Earlier in this series, we have already seen * How to connect a controlled SMIB system
|
| Open the SMIB model from the earlier tutorial. | Let us open the SMIB system which we modelled in earlier tutorial.
|
| I have already opened the SMIB system. | |
| Shift to network window and drag and drop Generator model onto it | Now the next task is setting up each component by entering the parameter data and power flow data. |
| Double click on the generator component | Let me enter the data for the generator model.
|
| I have entered all the data here. | |
| Cursor pointing on the system data block | The system data block is used to set the System base and frequency.
|
| Double click on the components to open parameter window. | Now as the parameters and power flow data are set for all the components we are ready to simulate it. |
|
|
Before simulating the model save it to a desired location. |
| Click on Check model | Firstly let us check the generator model by clicking on the tick mark icon at the top of the model.
|
| Close the Check Model windows | Close the messages browser. |
| Click on the simulation setup | Let us proceed to the simulation of the network model.
|
| Cursor on the simulation setup window. | Here, I am using dassl method and tolerance of 1e-06.
The simulation time is set to 0 to 10 secs.
|
| Cursor on the Simulation output window | The simulation output window pops up.
|
| Show Plotting perspective | We can see that the window has been changed to plotting perspective.
|
| Expand the model and each component in variables browser. | Click on the Expand button which is on the left side of each component.
Now we can see all the variables under that particular component. |
| Now let me show you the voltage profile at the fault bus i.e. Bus 2 | |
| Show the variables browser | Click on the Expand button on the left hand side of Bus 2.
We can see all the parameters of the bus.
|
| This plots the graph of Voltage at Bus 2. Let me close the Messages browser for better view. | |
| The Y-axis unit is in Per unit and the X-axis unit is in seconds.
| |
| During the fault i.e. from the duration 0.5 to 0.57 secs, there is a huge dip in the voltage profile. | |
| After the fault is cleared at 0.57 secs the voltage rises quickly. | |
| Cursor on the voltage profile of Bus 2 plot. | As the system is a controlled one, the voltage has less oscillations about its steady state value.
pa The voltage settles down after about 3.9 secs.
|
| Earlier in the series, the SMIB which was modelled, was an uncontrolled one. | |
| Let’s compare the time taken by the uncontrolled system to that of a controlled one.
| |
| This indicates that system regained its stability in less time with the help of controls like AVR and PSS. | |
| Cursor on the voltage profile plot | Here we can also see that the voltage doesn't drop down to zero at this Bus though it is the fault bus.
|
| We can also view the voltage profiles of the other bus i.e B1. | |
| After selecting B2 and B1 voltages, we can clearly see the voltage drop between the buses.
| |
| Clear the plot | Now clear these plots by unchecking the parameter checkboxes. |
| Show the plot of Delta curve of generator | We can also plot the Delta curve of the generator.
|
| Expand the generator and order61 | For this, expand the generator and order61 which is a sixth order generator.
Here we can see all the variables of generator. |
| Click on the checkbox of delta | Click on the checkbox of delta to plot its graph. |
| On the graph window | From the graph we can see the system is accelerated when the fault occurs at 0.5secs |
| On the graph window | The Delta then oscillates about the steady-state value after the fault is cleared.
|
