The Study on Micro Dynamic Simulation System in Electronics Transducer Circumstance

The dynamic simulation system is a very important method to analyze the electricity power system situation and test the protective relaying together with the second device. It is widely used in power system in our country. In view of the electronics transducer application, it's no needs to request the signal have the strong intensity and drive ability. So the paper put forward a micro electronics circuit to imitate the actual power system. The imagined model has the low voltage and small parameter, but has the similar dynamic characteristic with the actual power system: the electric generator is imitated by a signal generator which has the similar transfer function or dynamic response with it. The transmission line is modeling by the Pi-shape circuit consist of low power impedances and capacitances. The transducer is imitated by the intelligent conversion circuit. Compared with the present dynamic simulation system, the micro system has the advantage of less land occupation, less investment, low power consumption, low cost of operation and convenient operation. It's hopeful to condense the huge dynamic simulation laboratory into a flexible experiment table.
