Abstract

The invention provides an object-oriented implementation method for an intelligent electronic device of a digital substation. The method comprises the following steps of: a) defining data type of an object according to a capability description file of the intelligent electronic device, wherein the data type packages attribute and behavior of the intelligent electronic device and declares the object; b) performing system configuration, namely configuring the object according to an instance configuration file of the intelligent electronic device to generate a standardized object configuration interface file; and c) reading the instance configuration file by the intelligent electronic device to generate an IEC61850 communication real-time information base, guiding the standardized object configuration interface file into the information base, establishing and initializing the object and associating the attribute of the object with the corresponding IEC61850 communication real-time information base. By using the method, an object-oriented design is adopted at an information source to ensure that functional software of the intelligent electronic device is seamlessly interinfiltrated with an IEC61850 object-oriented information model without data mapping, flexible configuration of the intelligent electronic device can be performed, and the software maintainability is high.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to an object-oriented realization method of digital substation intelligent electronic equipment. Background technique [0002] The development of substation automation technology is a continuously deepening digital process. At present, digital substations have gradually begun to be popularized and applied from pilot projects. Through the optimal combination and design of digital information collection, transmission, processing and output processes, the digital substation realizes the intelligentization of primary equipment, networking of secondary equipment and automation of operation management in accordance with the IEC61850 standard at the process level, interval level and substation level. [0003] IEC61850 applies a series of relatively complete technologies, which can realize the interoperability between intelligent electronic devices (IEDs) in subs...
