Abstract

The invention is suitable for the field of power, and provides an intelligent electronic device of a transformer substation and data transmitting and receiving methods and systems thereof. The data transmitting method of the intelligent electronic device of the transformer substation comprises the steps of obtaining an identity identifier and a data attribute value of a data object carried by the data which are going to be transmitted by the intelligent electronic device based on a pre-built information model, wherein the information model is an IEC61850 standard based information model, the information model defines the data object of the intelligent electronic device and the data attribute corresponding to the data object, and the data attribute value corresponding to the data object comprises the identity identifier of the data object and the data attribute value of the data object which correspond to the identity identifier; packaging the data to be transmitted by the intelligent electronic device based on the pre-built information model and the obtained identity identifier and data attribute value of the data object; and controlling transmission of the packaged data. Due to the dynamic model, the maintenance work of the transformer substation caused by model change is reduced, the number of information entries in the model can be reduced obviously, and the resource expense of the computer system is reduced.

Description

technical field [0001] The invention belongs to the field of electric power, and in particular relates to a substation intelligent electronic device and a data sending and receiving method and system thereof. Background technique [0002] With the development of intelligent electrical technology, the construction of substations has gradually shifted from traditional stations to intelligent stations, and digitalization and networking have become important features of substation automation systems. The International Electrotechnical Commission (IEC) specially formulated the IEC61850 standard as the only international standard for the substation communication network to meet the needs of different manufacturers' equipment integration applications. It is translated and introduced in China, which is equivalent to adopting DL / T860 series standards in the electric power industry. The IEC61850 standard realizes the standardization of engineering operation of smart substations. It ...
