上海AEMS中数据共享平台的设计与实现

结合电力系统的工程实践,提出了数据共享平台的框架设计。数据共享平台的作用是为电力系统应用软件提供统一的接口获取数据,并保证数据的访问与数据所在位置、平台和应用的无关性。数据共享平台的框架由逻辑接口层、接口实现层和数据读取层组成,其中逻辑接口层为数据访问规定了统一的接口。该数据共享平台采用Java语言实现,基于IEC61970和IEC61968标准定义的公共信息模型与外部系统进行数据交换,具有跨平台、遵循国际标准、可扩展性强等技术特点。

Design and Realization of Data Sharing Platform in AEMS of Shanghai Power Grid

Based on the practice in power systems,a design of architecture of a data sharing!platform is proposed.The data sharing platform is used for providing uniform ioterfaces for data acquisition and ensures success of data acquisition no matter where the data is,what platform the data is on and what application the data is generated for.The data sharing platform is composed of a logical interface layer,an interface implementation layer and a data reading layer.The logical interface layer provides a set of interfaces for data acquisition.The data sharing platform is written in Java language and exchanges data with other systems based on common information model(CIM)defined by IEC 61970 and IEC 61968 standards.The platform is characterized by platform independence,compliance with international standards,and strong expansibility.
