Research On Information Interaction For Smart Shore Power Supply For Vessels System

At present,facing with the challenge of resource shortage,environmental pollution and climate change,the fundamental way of global energy development is to change development model of depending on fossil energy and to accelerate the implementation of electric power alternative.Emission from ships is the top cause of air pollution in coastal cities,while pollutant emissions will be effectively reduced and the electric power alternative target of port will realized by using shore power supply for vessels(SPSV)technology directly.Based on SPSV information interaction technology research,the information interaction between participants will be facilitated,the intelligent and visual management of SPSV will be realized and the power supply quality and reliability of SPSV will also be improved.Based on the analysis of the current situation of research and application at home and abroad,the demand of SPSV is analyzed,the architecture of information interaction structure of SPSV is built,the key technologies of SPSV is studied and applied to pilot projects and standardization work.The work of this article can be summarized as follows:(a)The current status and application of SPSV research at home and abroad.The construction of SPSV for electric power alternative project in Liaoning Province is introduced,focusing on the application of SPSV information interaction technology in the project.The significance of the development of SPSV technology to energy interconnection and electric power alternative is expounded.The main research content of this paper is proposed.(b)SPSV system demands analysis.Based on the demand for power supply,information,communication,monitoring and metering of SPSV,the interaction demands of SPSV participants,the functional demands of the system and other requirements are analyzed.And the typical business scenarios and use cases are described.(c)Construction of SPSV system information interaction framework.The related research on the information interaction architecture of SPSV system is carried out.The block diagram of the information interaction of SPSV system and the logical and physical architecture of SPSV system are put forward.The information interaction architecture of SPSV system is formed.(d)Carrying out research on information interaction model of SPSV system.The establishment method of SPSV information interaction model is introduced and information modeling on SPSV information interaction interface is carried out.The standard UML syntax is used to describe in the form of class diagram.The information model of information interaction interface is divided into three categories,namely Basic power supply class,ship electricity class,SPSV monitoring class.(e)Introduction to the specific application of SPSV information interaction model.Based on the demand for the development of SPSV technology and combined with the framework of electric power alternative standard system,the SPSV standard system architecture is established.Based on the analysis of demand information of SPSV system information interaction,the typical use cases of SPSV are analyzed in detail,and the domain,participants and their relationships of SPSV are clarified by defining the SPSV information interaction framework,Boundary and scope of the SPSV and the realization of the SPSV interaction interface function of SPSV are cleared.Through the UML business modeling method,information interactive interface of SPSV system is modeled to realize the transfer of model and information among different systems.
