Dynamic Exponential Load

Description:
This device is an implementation of the three-phase exponential load model. The load active power and reactive power vary as function of its voltage amplitude and frequency. This device is implemented... see more as described in [1]. It allows to perform classical and sophisticated dynamic-stability studies in EMTP. This device can be used in the load flow and time-domain simulations.

During the load initialization, the initial active power and initial reactive power are used to find the load-flow. The load voltage magnitude and phase with update from the load flow results automatically.

Digitial Twin Toolbox

Description:
The Digital Twin toolbox provides an example demonstrating how to synchronize EMTP device parameters with data received from a sender (Sender) through TCP/IP using the WebSocket protocol. A receiver (... see moreReceiver) accepting data in string format is also provided and may be started from the “Digital Twin Receiver” button device of the Digital Twin library.

To install:
- Download and unzip the file
- start the installer. Select the folder of the EMTPWorks version you which to add the Digital Twin Toolbox.
- Restart EMTP. A new Digital Twin library and a new Digital Twin example should be available.

More information is available from the help file of the Digital Twin device of the library.
