Electric energy quality analysis system and method based on big data

The invention relates to an electric energy quality analysis system and method based on big data, and aims to solve the problems that a power grid system cannot provide good electric energy quality due to various factors in the prior art, and the capacity and the installation place of electric energy quality treatment equipment cannot be accurately quantified. The electric energy quality analysis system comprises a monitoring data query module, an electric energy quality analysis module, a statistical analysis module and a system configuration module. The electric energy quality analysis method comprises the following steps: 1) monitoring electric energy quality through terminal monitoring equipment of a monitoring point, and generating terminal monitoring data; (2) collecting terminal monitoring data of the monitoring points in real time and offline through data access; 3) carrying out real-time and offline analysis and calculation tasks based on a big data processing platform Cloudera; 4) classifying and in
