A Comprehensive Query System for Grid Dispatching And Control Multivariate Data

As the control center of power grid operation, power grid dispatching and control covers power generation, transmission, transformation and other power production links. After years of construction, the power grid dispatching and control system has generated a large amount of data, showing the characteristics of various data types, huge data scale, and complex database table structure. The current multi-data query method is to write different database query languages for different databases to obtain data, which brings high difficulty to the use and analysis of data. This paper proposed a comprehensive query system for power grid dispatching and control multivariate data. Through natural language processing technology and rule computing engine, the input natural language question can be directly returned to the answer, thereby improving the efficiency of data query.
