Abstract

Combined propulsion plants (CPP) are increasingly being used on modern ships of foreign and domestic construction. A feature of such plants is that the energy for the movement of the vessel is generated in them in two (or more) different types of ship engines - heat and electric ones, working on a common propulsor. Combined plants are complex electromechanical systems designed to provide propulsion in various modes of ship operation and generate electricity in a cruising mode or during a lay-up. CPP combine the advantages of traditional propulsion plant with heat main engines and electric propulsion plants. The study of the physical properties and the principle of operation of CPP without a comprehensive study of the object using the model is impossible. Computer models and computer modeling are widely used to study the properties of complex objects. Nowadays, personal digital computers are widely used for computer modeling. Standard packages and programs are used as programs and packages for computer modeling.

Highlights

A propulsion plant is a complex of mechanisms and devices designed to ensure the movement of the vessel
When modeling autonomous starting up of main engine (ME) and electric propulsion motor (EPM), for clarity, it is assumed that the power of each engine separately is equal to the power of combined propulsion plants (CPP), taken as 100%
When working together and starting ME and EPM, it is assumed that the power of EPM is equal to 30% of the CPP power, the power of the main engine is 70%

Summary

Introduction

A propulsion plant is a complex of mechanisms and devices designed to ensure the movement of the vessel. The most widespread are plants with main heat engines and electric propulsion systems of the ship. These propulsion plants have well-known advantages and disadvantages, which determine their area of application [1,2]. CPP is a plant in which energy for the movement of a ship is generated in two (or more) different types of ship engines - heat and electric ones.
