Point-of-connection and network interface workspace

This section provides an overview of the PSCAD workspace which includes an example plant model ‘Windy Wind Farm’, referred to as the submitted plant model.

In the VM, the plant model workspace directory is E:\APPS\PSCAD\Client_Model . It contains the PSCAD model(s) submitted with the case. Functionally, your submitted PSCAD model is unaltered. You can make grid source connection alterations for integration to the NEM model.

In E:\APPS\PSCAD\Client_Model, double-click on the Workspace (.pswx) file to open the PSCAD workspace which contains your integrated model.

The PSCAD workspace includes the Results, Connect_NEM and submitted plant Projects. There may be more than one plant Project file depending on your model. In the Windy Wind Farm example, there is only one file named Windy_Windfarm. Do not edit the Connect_NEM project.

There is one Simulation Set named ‘default’. Do not alter the simulation sets.

In the Results project, you can update the Disturbance Controller component for implementing desired faults. Additionally, you can view measurements from various locations in the 4-state model. See Review and Plot Measurements and Configure the Disturbance Controller .

The Connect_NEM project is used to establish a connection to the rest of the 4-state model which is on an inaccessible server. An example of components in this project is shown below. Do not alter any components within this project.

Click Projects > Your Model Name to view the point of connection between your plant model and 4-state model as shown below. The model submitted is connected to the NEM Connection component which facilitates the transfer of data between your model and the NEM model.

The example below shows the NEM Connection components that makes the connection between your plant and the NEM model. It contains the ENI components which send and receive the PoC measurements to the master server.
Note: Do not alter anything inside this component apart from adding measurements.

 

Changes can be made to your model (for example, to alter model parameters between tests) and within the Results project which is detailed in Review and plot measurements.
