Parallel CIM/E file structured analysis method

Abstract

The invention discloses a parallel CIM / E file structured analysis method. The method comprises the steps of reading a CIM / E file to a computer memory; reading and cutting off a complete character string of an E file header element according to a CIM / E file specification; reading and cutting off an E file data block definition character string according to a CIM / E file specification; reading a datacontent character string of the data block; performing repeating until all element character strings of the whole CIM / E file are read, and storing related element character strings into character string fields of objectified hierarchical elements of the JAVA structure; utilizing a thread pool technology to analyze character strings of elements of each level of JAVA structure objectification in parallel, and differentially processing the character strings according to contents of data blocks and header elements in the analysis process; and finally, achieving parallel structured object analysisand assignment of the CIM / E file. According to the method, on the basis of structural object hierarchical description, all attributes and all numerical values are analyed in parallel by using a thread pool technology, and association of parsed data and a result object is achieved by virtue of structural description.

Description

technical field [0001] The invention relates to a parallel CIM / E file structure parsing method, which realizes the high-speed parsing of the power system data model description CIM / E file, and satisfies the high-speed description application of the power system data model and the efficient exchange of a large amount of online data. Background technique [0002] Power system data model description-E language specification (hereinafter referred to as "E language") is based on the object-oriented abstraction of the IEC61970301 power system common data model CIM, and is customized for the efficiency defects of CIM when it is described in XML. A new and efficient power system data model description language, the instance data formed by this language is a tokenized plain text data, which is called E-file in the power system. In the E file, the simple and complex data models of the power system are described concisely and efficiently through a small amount of markup symbols and gra...

Problems solved by technology

[0007] To sum up, Patent 1 invented a power grid model data maintenance and management method based on CIM / E files. As the power system becomes increasingly complex, the description of the power system model often consists of tens of thousands of nodes. Patent 1 adopts the mechanism of maintenance state and operation state , from the process, it is necessary to analyze and verify the modified CIM / E file twice, and finally complete the synchronization. With the increasing complexity of the CIM / E file, there is a bottleneck in the efficiency of parsing and verification, and there is a problem for the final maintenance and synchronization. Impact on efficiency and experience

Patent 2 mainly uses XPath statements to quickly locate the xml objects parsed by the general parser, and uses deserialization technology to realize Java business object conversion. XPath and other proprietary technologies belonging to xml cannot be directly used for reference and applied to CIM / E file parsing

In short, in the existing technology, the corresponding data is identified by marking symbols in the file, but the identified data cannot be structured, resulting in the data being unable to be stored and used efficiently and conveniently, and there are many ways to process files, which cannot form a unified standard
