Network Power Control of Screw-Steering Column of Electric Propulsion Vessels

Abstract

The subject of this work is to study the issue of ensuring regular navigation along the Northern Sea Route, which is much shorter compared to traditional routes passing through the South Seas and the Indian Ocean, as well as the possibility of its transformation into a national transport main waterway of the Russian Federation with a further increase in the economic contribution to the Russian economy of the Arctic zone, which is a strategic territory and it is important for ensuring the implementation of Russian national interests in the Arctic. At the same time, the necessity of using screw-steering columns with electric propulsion, which perform the functions of a steering device mover, for working on ships in harsh climatic conditions, is justified. Their main advantages are noted, namely: high maneuverability with maximum torque and thrust in any direction; reliable design without mechanical restrictions, which can withstand high sharply variable shock loads; high operational characteristics when working in ice and clean water. The problem of step-by-step regulation of power output to a screw-steering column with a main ship power plant, solved using hierarchical routing networks, is considered. It is noted that the size of the route tables supported by the switching equipment increases as a direct dependence of the increase in the size of the network, when the processor time for processing it increases, and the size of the packets exchanged by the communication equipment increases, which increases the load on the network. A general model of the network hierarchy for power monitoring and output, which is based on routers, modules, actuators, interface devices, etc., is proposed. The variants of power output from the main ship's power plant to the screw-steering column are analyzed.
