Development platform for automatic power station of ships

Abstract

The invention discloses a development platform for an automatic power station of ships. A system constructed by an experimental platform takes three diesel generating sets, a power grid and loads as controlled targets and a fieldbus network as control base to construct the experimental platform; control units of the generating sets are configured in a centralized / scattered manner, a controller and a monitor instrument are flexible and convenient in configuration, thus realizing the complementation of centralized monitoring and scattered control and the centralized recording and analysis of detected data, and the data has a network sharing function; a power generator of the ships is controlled by adopting a neural network intelligence multi-variable decoupling control method, and the system control function is completed by combining with energy management of the automatic power station; and depending on support software, the development system conducts the development of power station control software via Ethernet. The system is suitable for control methods and software development and research on efficient, safe and energy-saving running of the automatic power station of the ships, and facilitates deep research and functional development of the automatic power station of the ships and a power system thereof.

AI Technical Summary

Problems solved by technology

The electric propulsion of ships makes the power system more and more complicated; on the ocean, ships require orientation and constant speed navigation in an uncertain environment of wind / water flow; in bad weather, ships shake violently, and the hydrodynamic load of propulsion propellers changes greatly; When the ship enters or leaves the port / dock, the control of the high-power propulsion motor and the load change occur frequently. These working conditions cause the power system to be subjected to large uncertain loads, and the system enters a serious nonlinear and saturated state. The parameters The range of variation is large, and the transient process presents obvious nonlinear and unstable characteristics; however, the current ship generator control is still based on the simple closed-loop feedback control method of single input and single output, and the control quality of the power system is relatively low, which cannot meet the requirements of ship power. The system is used in the requirements of rapid capacity growth such as ship electric propulsion
