Abstract

The invention discloses a testing system for ring-digital and physical mixed real-time power simulation. A digital simulation work station is connected with an RTDS digital simulator through the Ethernet, the RTDS digital simulator is connected with an analog output interface card through fibers, and the analog output interface card is connected with a controller through hard wiring. The controller is connected with a four-quadrant linear power amplifier through hard wiring, and the four-quadrant linear power amplifier is connected with a power type physical model through a cable conductor to output voltage analog of the RTDS digital simulator to the power type physical model. The power type physical model is connected with a current measurement sensor, the current measurement sensor is connected with the analog input interface card through hard wiring, and the analog input interface card is connected with the RTDS digital simulator through fibers to return the current of the power type physical model to the RTDS digital simulator.

Description
