Method for coordinating and sharing transformer substation end and dispatching end model based on E language

Abstract

The invention provides a method for coordinating and sharing a transformer substation end and a dispatching end model based on an E language. The method comprises the following steps: (1) producing an SCD (security coding device) file; (2) reading the SCD file and analyzing the SCD file; (3) according to the read SCD file information, building an E language model file; (4) performing model checking for the E language model file; transmitting the checked E language model file to a dispatching automatic system; introducing the checked E language model file to the dispatching automatic system by an E language model file introducing tool in the dispatching automatic system, otherwise, entering step 5; and (5) modifying the E language model file which is not qualified. With the adoption of the method for coordinating and sharing the transformer substation end and the dispatching end model based on the E language, grid model sharing between the transformer substation end and the dispatching end can be realized, and the repeating, dividing and isolating modeling problem between the transformer substation end and the dispatching end is avoided.

Description

technical field [0001] The invention belongs to the field of electric power system and automation thereof, and in particular relates to a method for coordinating and sharing models of a substation end and a dispatching end based on E language. Background technique [0002] A unified information model is one of the important foundations for the development of smart grid technology. However, in terms of substation model description, the standards adopted by the local substation and the dispatching end are inconsistent. The substation end follows the IEC 61850 model, and the dispatching end follows the IEC 61970 / IEC 61968 CIM model. This inconsistency leads to problems such as segmentation and isolation of the power grid model and repeated modeling, which limits the further improvement of automation and intelligence. The 57th Technical Committee of the International Electrotechnical Commission (EC TC57) also attaches great importance to this issue, but there is no plan to dire...

Problems solved by technology

[0005] The main disadvantages of this solution include: the workload is huge, and it will take time to actually promulgate it as an international standard; there are certain requirements for the original IEC 61970 and IEC 61850 standards, that is, a slight change is required; although lossless conversion can be guaranteed theoretically , but judging from the application of the current grid model, the efficiency of this conversion is not too high, and the actual application efficiency after conversion to the CIM/XML model specified in the IEC 61970 standard is not high

[0008] The disadvantages of this solution include: the existing standard
