TSAT-EPMU

Simulated PMU Data Generator

The ePMU module is an add-on function for TSAT, which provides time-synchronized phasor data from a power system model, similar to those measured by PMU.
Because the simulations with TSAT are done with the positive sequence phasor model, ePMU is capable of simulating systems of very large sizes, up to 10,000 buses, in near real time. For even larger system models, a save/playback feature is available to generate PMU data.

Approach

The ePMU module is based on the following techniques:

  • Near real-time simulations using TSAT:
    • Simulations are controlled to progress at near real-time.
    • Virtual PMU can be placed at any locations in the system model to obtain emulated phasor data.
    • Emulated phasor data is streamed with accurate reporting rate.
  • Capability of interacting with external switching/ control actions:
    • This can be done “on-the-fly” during simulations.
    • A rich set of switching/control commands are available.
  • Compliancy with IEEE C37.118 standard:
    • Streamed phasor data at specific reporting rate and TCP port.
    • External switching/ control actions through extended command frame.
Applications

The ePMU module can be used for a variety of applications, including:

  • Testing and validation of situational awareness tools.
  • Design and development of decision support, intelligent diagnoses, and analysis applications for grid events.
  • Provision of data source for training purposes, such as Dispatcher Training Simulator (DTS).
  • Determination of appropriate locations to install PMU.
  • Design and study of wide-area controls.
  • Assistance in planning studies and system model validation.
