Abstract:

Abstract:Ship lift for Three gorges have the characteristics of huge tonnage,high lift hight,changeable upstream and downstream,and with the
world hardest technology and biggest scale.Based on the alignment experiment in the ship lift plant,and the method of add a coordinator control module between AB
s PLC and Siemenss variable frequency gearing.The experimental data shows this method greatly enhanced synchronization performance among each suspension point.

Key words: Keywords:ship lift, communication, simulation, synchronous analysis
