【Abstract】 An AC drive simulation system, composed of two PCs and two high speed communicat ion cards on the basis of PCI, is presented. Its software is designed to calcula te the running parameters of the AC drive system, including transformer, quadran t rectifier, DC circuit, inverter, AC motor and train load. The simulation resul ts are converted with a D/A converter as the sensor signals required by the real time simulation of AC transmission controllers.更多还原
