Abstract

The invention discloses a hydraulic power plant comprehensive data analysis method. A professional theme template is defined according to the analysis requirement of all professional data of a hydraulic power plant, and the professional theme template comprises a data set extraction rule, an index, an algorithm, a view, alarm and other factors; a related professional theme template is selected, a device to be analyzed and a historical data time frame are associated, a related professional extraction scheme is generated, and an analysis report is output. According to the hydraulic power plant comprehensive data analysis method, an organization form of the professional theme template is proposed under the application environment of mass heterogeneous data, the purpose of quickly making a data extraction scheme is achieved, and the problems that the data analysis and extraction process are low in efficiency and poor in expansibility are solved.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a comprehensive data analysis method for a hydroelectric power plant. Background technique [0002] With the rapid development of information processing technology and the deepening of the construction of intelligent hydropower plants in the hydropower industry, due to differences in development time, application platforms, and data storage structures of subsystems such as computer monitoring systems, status monitoring systems, and protection systems in traditional hydropower plants, data Tens of millions of business data are limited to the use of each system itself. This mode leads to low utilization rate of massive data resources and poor integration among various disciplines; at the same time, due to the existence of information islands, there are prominent problems such as low consistency in operational decision-making. [0003] Based on the above ...
