Abstract:

The dynamic simulation system is a very important method to analyze the electricity power system situation and to test the protective relaying together with a second device. The micro dynamic simulation system was put forth to simulate a power system. The synchronous generator was imitated by a signal enerator which has the similar transfer function or dynamic response with it. The transmission line was modeled by a ∏-shape circuit consisting of low power impedances and capacitances. An intelligent data interface conversion unit will seamlessly connect the output of the system with the second relay devices. Compared withthe present dynamic simulation system, the microsystem has advantages of little investment, little power consumption, low performance expense and convenient operation.

Key words: micro dynamic simulation system; synchronous generator model; ∏-shape equivalent circuit; data interface conversion unit
