摘要
变电站模型是电力系统自动化技术应用的重要基础。IEC 61850对变电站模型的描述全面、详细,但处理效率不高,且在调度环节得不到应用。通用信息模型(common information model,CIM)对变电站模型的描述则较为简约,且CIM/XML处理效率不高。CIM/E克服了CIM/XML效率上的问题,但模型不够全面。从一次设备模型、二次设备模型、通信模型、控制模型、采集模型、保护模型6个方面对CIM/E规范进行了全面扩充,使之如IEC 61850一般能够全面描述变电站模型,并通过原型系统进行了有效验证。这样扩充后的CIM/E模型有望成为变电站和调度端公用的模型描述方式。
The substation model is an important foundation of power system automation technology applications. IEC 61850’s substation model description is comprehensive and detailed, but the processing efficiency is not high, and can not be applied in the dispatching systems. CIM’s substation model description is relatively simple, and CIM/XML processing efficiency is quite low. CIM/E overcomes CIM/XML’s efficiency problem, but the model is not comprehensive enough. This paper fully expands the CIM/E specification to include primary device model, secondary device model, communication model, control model, protection model and data acquisition model, so that the substation model can be comprehensively described just as IEC 61850, and be effectively verified by the prototype system. Thus the expanded CIM/E model is expected to be the public substation model description of substation and dispatching automation systems.
