【摘要】：近年来,随着电力电子技术、交流调速理论、现代控制理论、电机设计与制造技术的发展,电力推进技术发展迅速,电力推进设备在破冰船、渔船、游轮等船舶上应用广泛。通过陆上试验装置进行仿真实验是电力推进技术研究的重要方法之一,因此进行试验装置的操控平台设计,并进行仿真实验研究对于电力推进技术的发展具有良好的促进作用。本课题依托大连海事大学“船舶智能微网与电磁推进实验室”项目,进行了操控平台设计与仿真实验研究。在电力推进负载模拟系统原理分析的基础上,进行了操控平台的整体设计。提出了一种利用OPC通信技术将组态软件WinCC与仿真软件Matlab结合的负载仿真方案,并确定了实际船舶推进系统的转速、转矩缩放方法。利用组态软件WinCC并融合图文显示技术进行了人机交互系统设计。设计内容包括：通信系统、操作界面等,实现了在计算机上进行仿真系统的过程控制、状态显示、监测报警等功能。根据船舶推进原理,将船舶与螺旋桨看作整体,在Matlab/Simulink开发环境下搭建螺旋桨负载仿真模型。整个仿真模型主要由输入输出模块、螺旋桨负载计算模块、转矩折算模块组成,能够根据实时转速输出符合螺旋桨负载特性的转矩控制指令。针对实际船舶螺旋桨四象限负载特性相关资料缺乏的情况,利用船舶参数与经验公式进行了船舶螺旋桨参数的设计,根据Wageningen B系列螺旋桨水池实验结果,应用前馈型的神经网络算法预测了所设计螺旋桨的四象限特性,确定了负载仿真模型的螺旋桨推力系数、转矩系数。利用操控平台进行了船舶正车启动、停车、正车转倒车三种典型工况下螺旋桨负载仿真实验,实验结果表明,操控平台运行稳定,负载仿真建模正确,能够实现螺旋桨负载特性的模拟。所设计的操控平台既可为方案论证、教学提供实验环境,又可为其他类型机械负载模拟提供工程参考。
[Abstract]:In recent years, with the electric and electronic technology, the theory of AC speed regulation, the modern control theory, the development of the motor design and manufacturing technology, the electric propulsion technology has developed rapidly. The electric propulsion equipment is widely used in the ships of ice breaking ships, fishing boats and cruise ships. It is an important method for the research of electric propulsion technology to enter the simulation experiment through the land test device. First, the design of the control platform of the test device and the research of the simulation experiment have a good effect on the development of the electric propulsion technology. Based on the project of the "ship intelligent micro network and the electromagnetic propulsion laboratory" of Dalian Maritime University, the design and simulation experiment of the control platform are carried out.
On the basis of the principle analysis of the electric propulsion load simulation system, the overall design of the control platform is carried out. A load simulation scheme is proposed, which combines the configuration software WinCC with the simulation software Matlab by using OPC communication technology, and determines the speed of the actual ship propulsion system and the method of turning moment and zoom.
The design of human-computer interaction system is designed by using the configuration software WinCC and the graphics and text display technology. The design includes communication system, operation interface and so on. It realizes the function of process control, state display and monitoring and alarm on computer.
According to the principle of ship propulsion, the ship and propeller are considered as a whole and the propeller load simulation model is built under the environment of Matlab/Simulink development. The whole simulation model is composed of input and output module, propeller load calculation module and torque conversion module, which can output torque control according to the load characteristic of propeller according to real time speed. Instructions.
In view of the lack of relevant data about the four quadrant load characteristics of the actual ship propeller, the ship propeller parameters are designed by using the ship parameters and empirical formulas. According to the experimental results of the Wageningen B series of propeller pools, the feedforward neural network algorithm is used to predict the four quadrant characteristics of the designed propeller, and the load is determined. The propeller thrust coefficient and torque coefficient of the simulation model.
By using the control platform, the propeller load simulation experiment of the propeller under three typical operating conditions is carried out. The experimental results show that the operation of the control platform is stable and the load simulation is correct, and the load characteristic of the propeller can be simulated.
The designed control platform not only provides experimental environment for program demonstration, teaching, but also provides engineering reference for other types of mechanical load simulation.
