Within the Simulation Environment

AGORA's simulation environment is based on load flow data and has a strong graphical user interface that offers field and SCADA emulation. It supports any load, mode of generation and topology. It is specifically designed to familiarize operators with grid behavior under all conditions. And it can reproduce or simulate massive disturbances to evaluate various restoration strategies. Features include:

  • Base Case Generation - The simulator uses system snap shots to generate a base case. The image transmitted to the simulation environment contains current topology, analog and digital values and the network model (topology and values are modifiable).

  • Topology Changes - Base case topologies can be modified as needed using breakers and isolators included in the network model. These changes can be performed via graphic or text editing environments. Information is obtained directly from the database, which can be consulted on-line (breakers, isolators, relay alarms, etc.).

  • Load And Generation Changes - Load and generation simulations can be changed individually or scaled. To simulate small variations or larger disturbances, the active and reactive load and generation can be scaled independently.

  • Protection Relays - The system automatically accounts for the effect of the protection relays in case of over voltage, under voltage and overloads.

  • Disturbance Generation - Any change in topology, load or generation can be manually generated to simulate disturbances of any kind. A high level language lets users replicate topological changes with massive disturbance generation. This information may be submitted to AGORA's real time on-line monitoring system—or it may simply be used to compute a final system status after such disturbances. Simulated disturbances and resulting data are visualized in a graphical environment.

  • Restoration Evaluation - The AGORA restoration module transmits restoration plans to the simulation environment. Solutions are then evaluated and stored for further analysis. A simulation environment with reduced functionality is also available in the real-time system. The evaluation process uses a heuristic similar to the one used for restoration path calculation. It can also be used to evaluate manually generated alternative plans.

  • Alarms and Events - The simulation environment contains powerful tools for alarm masking and filtering. Events can be simulated in user-specified chronological order for a user-specified duration, time of day, season, etc.
