The Research And Development Of The Marine Medium Voltage Power Station Based On PLC

The marine power station simulator is an effective facility to crew training center andtraining of maritime colleges in training modern marine electromechanical device managementpersonnel. The amendments to the STCW78/10convention in Manila added to the mandatoryminimum requirements of certification for marine electronic technical officer and electronicstechnician, and set the marine medium voltage power station system as mandatory trainingcontent. The simulation object of traditional marine power system is low voltage power system.It is difficult to meet the need of the education and training when used in training the electronictechnical officer. Therefore, the research and development of medium voltage power stationsimulator adapting to the modern ship is important to training the electronic technical officer.This paper chooses marine medium voltage power station as the studying object, mainlyanalyzes the composition and characteristics of medium voltage power system, based on superlarge container ship as model, establishes the simulation model by design appropriate technicalsolutions. The core content of this thesis is to design the control program for Haiwei PLC controlsystem, using HaiwellHappy programming software of Haiwei PLC as the main developmenttool,designing PLC ladder diagram to achieve simulating the control rules of medium voltagepower system, using Haiwellview of human machine interface software as the supportingtool,desingning human machine interface on the touch screen to achieve monitoring function ofmedium voltage power system,selects the RealInfo configuration software as the upper monitordevelopment software, designing the software system to achieve fault setting and virtualoperation of system.The simulation of power station system uses technical route by combing PLC controltechnology with network communication technology, configuration technology and databasetechnology, it adopts the modular PLC control system in terms of hardware, configurationtechnology and virtual reality technology in terms of software, completing the Simulation ofmarine medium voltage power system. The whole system has the characteristics of flexibility,easy maintenance, high reliability, advanced technology meeting with the amendments to theSTCW78/10convention in Manila requirements for training the electronic technical officer.
