| Slide Number 4
Prerequisites |
To follow this tutorial, you should have knowledge of:
For relevant OpenModelica tutorials, please visit our website. |
| Slide Number 5
Modelling of a SMIB system using OpenIPSL |
Earlier in this series, we have already seen how to
|
| Slide Number 6
What is a controlled SMIB system? |
In this tutorial, we will learn how to model a SMIB.
|
| Before getting started we will briefly learn about Automatic Voltage Regulator and Power System Stabilizer. | |
| Slide Number 7
What is a controlled SMIB system? |
Automatic Voltage Regulator(AVR)
|
| Slide Number 8
What is a controlled SMIB system? |
Power System Stabilizer(PSS)
|
| Slide Number 9
What is a controlled SMIB system? |
Optimal tuning of AVR controller and PSS parameters is necessary.
This is to obtain better voltage regulation and oscillation damping in the system. |
| Slide Number 10
How to model a SMIB system? |
Before launching OMEdit , let us look at Single Line Diagram of SMIB system. |
| Slide Number 11
How to model a SMIB system? |
This SLD helps us to get an overview of our system. |
| Launch OMEdit | Now let us launch OMEdit. |
| Open OpenModelica and OpenIPSL | Once OMEdit is launched, we will create a new Modelica Package.
Before creating it, let me include the OpenIPSL library. As demonstrated earlier in the series, navigate to “File” --> “System Libraries” --> “OpenIPSL”. |
| Highlight and click on the icon which is below the file to the top left corner . | To create a new "Modelica Package", click on the icon at the top left corner below the file.
We see a pop-up window. |
| Point at the name column. | Now type the desired name in the Name column.
While entering the name, make sure there are no spaces and the name doesn't start with a number. It also doesn't accept any special characters. |
| Create a package with the name “SMIB_Controlled”
Highlight the package in libraries column. |
Now I will type the name as "SMIB underscore Controlled".
In the Specialization column drop-down, select Package and click Ok. We can see a package in the Libraries Browser column. Under this package, we will create the models. |
| We have to create two models under this package
1. Network. 2. Generator. | |
| Create two models under the main package.
Click on "New Modelica class" >> type name="Network" and Specialization="Model". |
Now to create the models, right-click on the SMIB_Controlled package.
And click on "New Modelica class". We see a pop-up window. Type the name as "Network" and Specialization as "Model". |
| Highlight the class column SMIB_Controlled
Click on "OK". |
Here we can see that the Insert in class column is automatically filled as "SMIB underscore Controlled".
This is because we are inserting this model in the SMIB underscore Controlled package. Click on "OK". |
| Repeat the above procedure. | Now follow the same procedure to create Generator model.
While doing so, type the name of the model as “Generator”. |
| Point to the Expand button >> click on it | After creating the models, you can see the Expand button to the left of the package.
Expand the package by clicking on the Expand button. |
| Open network model. | We can see two models already opened.
Click on the Network tab at the top. Now let us drag and drop the required components to build the network. I am closing the Messages Browser for better view. |
|
Slide number 12 |
The following are the components required to model a SMIB system.
|
| Slide number 13 |
|
| Open OMEdit window | Let’s go back to the OMEdit window. |
| Drag and drop all the components | Drag and drop all the components required on the Network window as shown. |
| Drag and drop all the described components | For Buses navigate to "OpenIPSL--> Electrical--> Buses".
Drag and drop the Bus on the Modeling window of the Network. |
| Type name=Bus 1 >> Ok | Then type the component name as Bus 1 and click on Ok. |
| We require three Buses as mentioned earlier in the requirements. | |
| Repeat for Bus 2 and Bus 3 | Now do the same for Bus 2 and Bus 3. |
| Drag and drop all the described components | In a similar manner, drag and drop all the required components. |
| Drag and drop the required components on to network model window. | For two winding transformers, navigate to "OpenIPSL--> Electrical--> Branches--> PSAT-->Two winding transformer".
For Power Lines, navigate to "OpenIPSL--> Electrical--> Branches--> Power Line". For Infinite Bus, navigate to "OpenIPSL--> Electrical--> Buses--> Infinite Bus". For Fault Block, navigate to "OpenIPSL--> Electrical--> Events--> Power Fault". For System Data, navigate to "OpenIPSL--> Electrical-->System Base". |
| Let us connect the components together according to the single line diagram shown earlier. | |
| Connect the components as described | To connect two components, click on the power pin of the first component.
Drag and click on the second power pin as shown. |
| Connect the components in Network model as shown in SLD. | Between Bus1 and Bus2, the Two winding transformer is connected.
Bus 2 and Bus 3 are connected via two power lines in parallel. |
| Connect the components in Network model as shown in SLD. | The infinite bus is connected to Bus3.
But before that rotate the Infinite bus component using "Ctrl+R" |
| The Power Fault block is connected to Bus 2. | |
| Connect the components in Network model as shown in SLD. | The system data block is placed on the Network model plane.
This provides the system with base and frequency for all the components. |
| Let me zoom in for better view.
For this, I am pressing CTRL and Plus symbol simultaneously. | |
| Switch to Generator model window | The Network is connected now.
And let us go to the Generator modelling window. The Generator used here is of order six. |
| Drag and drop components on to Generator modelling window | Now let us drag and drop PSS, AVR and Generator on to the Generator modelling window. |
| Connect the components as described | For Automatic Voltage Regulator (AVR)(Order Three), navigate to "OpenIPSL--> Electrical--> Controls--> PSAT-->AVR-->AVR Type Three". |
| Connect the components as described | For Power System Stabilizer (PSS) (Order Two), navigate to "OpenIPSL--> Electrical--> Controls--> PSS-->PSS Type Two". |
| Connect the components as described | For Generator (Order Six), navigate to "OpenIPSL--> Electrical--> Machines--> Order 6". |
| Connect the components as described | For Power Pin, navigate to "OpenIPSL--> Interfaces--> Power Pin".
This Power Pin acts as an interface between the Generator and Network models. |
| Adjust and resize the components
|
Adjust and resize the components as shown to make it look better.
The generator used here is of order six. PSS and AVR is connected to the generator to achieve required control. AVR controls the field voltage of the generator taking the generator terminal voltage as input. PSS takes rotor speed as the input and fits AVR. |
| Let us connect the components.
Let me zoom in for better view. | |
| Point or highlight as per narration | The AVR takes the generator terminal voltage as input.
Generator "V" is connected to AVR Type Three "v" The Initial Field voltage (Vf0) of the generator is given to AVR Type Three as input. |
| The output "Vf" of AVR Type Three is connected to input "Vf" of the generator. | |
| Point to PSS input signal | PSS input signal is connected to 'omega'(Rotor speed) of the generator. |
| Point to the output of PSS | The output PSS is fed to "Vs" of the AVR Type Three. |
| Point to the connection | The Mechanical power is not controlled here.
So Pm and Pm0 of the generator are connected together. |
| Point to PwPin | The power pin of the generator is connected to Power Pin. |
| I am closing the Libraries Browser. | |
| Shift to Icon view of the Generator model | Now shift to the icon view using the "Icon View" which is at the top left corner of the Generator Model window. |
| Here I will use a circle to represent my generator and its controls. | |
| Select the ellipse | Select the ellipse at the top toolbar to draw a circle as shown. |
| Drag the cursor to draw a circle | After selecting ellipse, click on the top left corner and drag the cursor to draw a circle. |
| Shift to network window >> drag and drop Generator model onto it | Now let us go back to our network modelling window.
Let me open the Libraries Browser window. Here drag and drop the Generator model in your package. |
| Navigate to "SMIB_Controlled-->Generator"
Close Libraries Browser Connect to Bus1' |
Navigate to "SMIB underscore Controlled-->Generator"
I am closing Libraries Browser for better view. Now connect it to Bus1. This makes the connections complete. |
| Save by pressing CTRL+S keys | Before simulating the model, save it to a desired location.
For this, I am pressing CTRL+S and then a pop up opens up. Select the desired location and save it. |
| This brings us to the end of this tutorial. | |
