To meet the requirements of test investigation into AC drive and frequency conversion power supply used in vessel and port, an AC drive test-platform is designed using asynchronous motor to simulate load energy feedback mode. The test-platform consists of power supply subsystem, drive subsystem and measuring subsystem. Combined with the high-accurate torque transducer and torque control strategy, the test-platform can provide six voltage classes for the test system, and carry out the experiment of electric drive control system in vessel and port, the experiment of power quality in AC drive system, the united modulation of power propulsion system in medium and small sized vessels on land and the com- prehensive experiment of frequency conversion power supply, etc. Results show that the platform consumes less electric energy, its function and performance can meet the requirements of drive system in vessel and port, and it can provide test environment and technological support for the development of high-power AC drive system in vessel and port.
