摘要
在目前的技术条件下,探讨了基于IEC 61970标准的能量管理系统／调度员培训系统(EMS／DTS)需要解决的关键技术问题,包括数据库平台、公共信息模型(CIM)电网模型的维护、应用软件的组件化封装和跨平台的异构系统的实现方法等。开发了由后台数据库和软总线组成的异构数据平台。其中,后台数据库采用3种数据管理模式用于数据的存储、检索与处理,既保证了开放性又提高了系统效率。软总线则基于实时公共对象请求代理体系结构(CORBA)的中间件基础,全面支持组件接口规范(CIS)标准。还开发了一套符合CIM特点的图模一体化系统,同时也能支持离线规划功能。对于应用软件不同模块的功能和应用特点,采取了不同的封装策略,测试表明这种策略是合理、实用的。
IEC 61970 is one of the most important standards of the new-generation EMS/DTS system. This paper proposes the key technical issues in developing the EMS/DTS system based on IEC 61970. The methods for implementing the database platform, CIM model, EMS API and heterogeneous supporting system are discussed. First, a heterogeneous database platform composed of database and soft-bus is proposed. Then three types of database management modes are adopted in the background database to store, retrieve and process data, in which the architecture guarantees the openness and efficiency of the system. Then the soft-bus, based on the real-time CORBA middleware, supports the CIS standard in an all-round way. Secondly, a WYSWYG (What you see is what you get) method for power system modeling, firmly compliant with CIM, is presented. Furthermore, different strategies are applied to wrap the legacy EMS/DTS modules. It is shown by test results that this strategy is feasible.
