Analysis method of influencing factors of modern tram operation energy consumption

In view of the traditional tram energy consumption analysis method be lack of judge and analysis of abnormal data as well as is difficult to effectively discover the characteristics of energy consumption data and the potential relationship between data, an integration method of tramcar energy consumption analysis with control charts and grey correlation analysis is proposed. By using the control chart, the fluctuation of energy consumption data is analyzed, and the influence degree of each factor on energy consumption data is analyzed by grey relational analysis. The simulation experiment is carried out by using the energy consumption data of Guangzhou tram cars. The result shows that the tram energy consumption analysis method proposed not only can analyze the characteristics of all energy consumption data and mine potential relations among data, but also can monitor the fluctuation of energy consumption data and identify the abnormal energy consumption data as well as related factors that affect energy consumption.providing auxiliary decision-making for energy saving of tram system, which can provide some reference for the analysis of the energy consumption data of the running tramcar.
