Power distribution network data checking method based on international electrotechnical commission (IEC) 61968 standard

Abstract

The invention relates to the field of power system automation, in particular to a power distribution network data checking method based on the international electrotechnical commission (IEC) 61968 standard. The method is characterized in that a system used by the method comprises a grammar checking module, a semantics checking module and a log module which are sequentially communicated. The method includes the following steps: (1) configuring a checking machine for original data to enable the original data to be applicable to the common information model (CIM) standard used by CIM data; (2) judging whether grammatical mistakes exist in the CIM and writing the grammatical mistakes into the log module; (3) loading in the CIM standard used by the CIM data according to the configured checking machine; (4) judging whether semantics mistakes exist in the CIM model and writing the semantics mistakes into the log module; and (5) outputting an analysis result and a journal. The method improves power distribution network data quality, improves automatic operation level of a power distribution network accordingly, reduces outage cost, and has great social and economical value for safe operation of the power distribution network.

Description

technical field [0001] The invention relates to a power system and its automation, in particular to a method for verifying distribution network data based on the IEC61968 standard. Background technique [0002] In order to solve the problem of distribution network application integration, the International Electrotechnical Commission (IEC) has formulated the IEC61968 series of standards. The IEC61968 series standard regulates the data exchange process and data model of distribution network information integration, and is the cornerstone of distribution network automation construction. Among them, in the data model part, IEC61968 uses the Common Information Model (Common Information Model, hereinafter referred to as CIM model) specified in Part 301 of the IEC61970 standard to describe the main objects of the power grid, especially the data related to the operation of the power grid. The CIM model of IEC61970 is mainly aimed at the grid object of the transmission network. For...

Problems solved by technology

[0005] 1. Each power company and manufacturer have their own understanding of the CIM model, which naturally leads to differences in understanding, and the definition of the CIM model is also imperfect, which exacerbates the deviation in understanding; the understanding of the CIM model by all parties Errors, sometimes even errors, lead to various problems in the process of generating, converting, transmitting, exchanging, and using CIM model data

[0006] 2. The IEC61968 standard and the IEC61970 standard are still in the process of evolution and revision. During this period, multiple CIM model versions have appeared. If the CIM model versions used by all parties are inconsistent, even a small difference on the CIM model will affect the model data. Adverse effect of the exchange

[0007] 3. In the process of CIM model data generation, due to the defects of the original data of the distribution network and the improper handling of the CIM model data generation tools, there may be various problems in the generated CIM model data, resulting in problems when exchanging data

[0008] The interoperability and data exchange of distribution network applications are necessary means of information integration. The defect of this CIM model data hinders the smooth progress of interoperability and data exchange, and hinders the information automation process of distribution network.
