基于CORBA的应用软件标准接口的研究

摘要:在电力行业中应用的各种自动化系统之间普遍存在着诸如电力系统建模、数据结构定义等方面的差别,因此,无论升级已有的系统还是进行相关系统的集成都是相当困难的。而IEC EMS-API标准的制订为解决这些问题提供了依据。根据EMS-API标准和CORBA(公共对象请求代理构架),说明了开发标准程序接口应用的具体方法;并且给出了为黑龙江电网能量管理系统中的潮流程序而建立的标准化的接口服务,测试结果表明文中方法可行有效。由于CORBA技术与EMS-API标准的结合,使得所开发的潮流应用具有了开放性。最后,讨论了EMS-API的不足之处。

RESEARCH ON STANDARDIZED APPLICATION PROGRAM INTERFACE BASED ON CORBA

Because of the differences among information technology systems of power utility, such as different power system model, different data structure, etc. it is very difficult to integrate or upgrade these systems. Therefore, IEC Energy Management System Application Program Interface (IEC EMS-API) is going to solve such problems. According to EMS-API and CORBA (Common Object Request Broker Architec-ture), the method to build up applications is studied and a standard interface service for a legacy power flow program applied in a provincial power network is given. Testing results show the method is feasible and effective. By combining CORBA and EMS-API standards, the application involved in this paper is open and flexible. At last, some defects of EMS-API is discussed.
