Abstract: This paper studies the dynamic characteristics of the production operations in the outland harbour under the network structure of the independent power station network.Since the multi-way switchable mode is usually adopted,the dynamic range of the load working conditions is large,and different networking modes make the state analysis difficult to be solved by a single model,the design of the stable control system faces a great challenge.By structure analysis under different networking mode of the new ladder network,a dynamic characteristic model was built according to the new ladder structure,and the control system was designed to maintain the stability of the electromagnetic power and the output voltage.The analysis of the dynamic response was done according to the change of the topology.And the simulation of the fault status proves that the variability of the new structure can ensure electricity supply for the load.

Key words: port power system, dynamic characteristic, ladder network, topology
