基于EC61850标准的变电站自动化若干关键技术研究 In order to realize communication services of IEC 61850 and ensure interoperability, software structure,external interface characteristic,and data structure of IED have its own speciality and complexity.Because of that,an advanced development tool is required for realization of IED software.A solution based on IEC 61850 is proposed in this chapter,which develops IEDs by means of IEC61131-3 standard based graphic oriented programming technique,speeds up IED software's development and enhances software's openness as well as other advantages owned by conventional graphic oriented programming technique.A software scheme is proposed and some key technologies,such as the parameter association between graphic oriented programming interface and IED's data memory,are researched.The solution is propitious to improve the flexibility of development and research,standardization and interchangeability of IEDs. In the fourth chapter,considering huge amount of legacy IEDs which are not conformed to IEC 61850,a new protocol-mapping method,named metadata-mapping using XML Schema technology to model metadata of protocol and protocol-mapping, is proposed.Then a configurable architecture of IEC 61850 gateway by metadata mapping is designed.The gateway loads files of the metadata models to realize mapping between different legacy protocols and IEC 61850.The novel gateway has generality because of flexible protocol conversion by configuration files. In the fifth chapter,an information integration platform IIP )conformed to IEC 61850using primary object oriented unified modeling,is proposed.Substation automation system faced to the future could use integrated IEDs based on IEC 61850, that is,one (or more than one as redundancy)multifunction IED corresponding to one primary object realizes functions;previously realized by several IEDs corresponding to several systems.For substation with many legacy systems,IIP above every application system could be adopted to access application systems and IEDs.The IIP unifies external hardware interface and releases production and management information in a unified way,thus ensures information consistency.Key technologies,such as dynamic modeling of platform model,coordination of concept object model of heterogeneous systems,adaptation of model data of heterogeneous systems,have been studied. In the sixth chapter,as an example of utilizing partial research results in practical project,an IIP is put into implementation in an 110kV substation in Shanghai.The IIP has accessed several main systems.Several key technologies of the IIP are described in this chapter,such as architecture of the platform,step of modeling,software and hardware scheme,performance index,and so on.
