Abstract

The invention discloses a multi-source heterogeneous power grid operation parameter analysis system which comprises a data acquisition and analysis module, a multi-professional parameter fusion module, a multi-professional parameter fusion module and a professional parameter quality analysis module. The data acquisition and analysis module obtains multi-source power grid parameters, and analyzes the multi-source power grid parameters to obtain a heterogeneous power grid parameter file, the multi-professional parameter fusion module respectively obtains automation parameters, operating mode parameters and power grid parameters of the relay protection profession, and conducts contrastive analysis and data fusion processing to obtain fused automation parameters, operating mode parameters and power grid parameters of the relay protection profession, the multi-professional parameter fusion module conducts contrastive analysis and data fusion processing on the automation parameters, the operating mode parameters and the power grid parameters of the relay protection profession, and builds the corresponding relation between the profession parameters which exist in a set-file mode, and the professional parameter quality analysis module respectively obtains fused profession power grid parameters, calculates the parameter variation degree between the profession power grid parameters, and conducts quality analysis and parameter correction on the parameters. According to the technology, consistency of different profession power grid parameters is improved, and the accuracy and the reliability of analysis results are greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a multi-source heterogeneous power grid operating parameter analysis system. Background technique [0002] The quality of the basic data of power grid operation directly determines the practical level of various advanced analyzes and applications in the power dispatching control center, and also seriously affects the accuracy, reliability and leanness of power dispatching control. The basic data of power grid operation mainly includes models, parameters, measurement data and other parts, each of which will have a direct impact on its quality; operation and maintenance experience shows that the main factor affecting the quality of basic power grid operation data and the effectiveness of state estimation results is the power grid. parameter. [0003] For the problem of power grid parameters, the focus of industry research is mainly on parameter identification an...
