Dear raifana19,
Yes, you can use a IEC61850 Server Simulator (Like InfoTech 61850 Server).
But, to test the topology processor, you also can set the ActiveSource property of the Swtich/Breaker position measurement of the device, like “Operator”, and manuallty configure it position.
You can find more information about this configurations on the “ElipsePowerTutorial”, on the Installation folder of the Elipse Power.
In addition, our algorithm takes into account only the topological state of the model, not taking into account the measured voltage. Therefore, you can test the algorithm only through the position of the switches and circuit breakers.
