Control chart-based tramcar system energy consumption analysis method

Abstract

The invention discloses a control chart-based tramcar system energy consumption analysis method. The method comprises the following steps of: firstly analyzing components of tramcar system energy consumption; acquiring energy consumption data; analyzing and judging abnormal condition of the acquired energy consumption data through an X-Rs control chart; for the abnormal energy consumption data, analyzing reasons and getting rid of abnormal data until the X-Rs control chart analyzes that the data is normal; and carrying out grey relational analysis on the normal energy consumption data. The invention discloses a plurality of data mining methods; by monitoring and analyzing fluctuation conditions of tramcar system energy consumption data through a control chart theory, abnormal energy consumption data can be rapidly recognized; and by carrying out correlation analysis on energy consumption influence factors through a grey relational algorithm, a relationship can be established among theenergy consumption data, the data can be deeply analyzed, the energy consumption abnormal data can be recognized, the energy consumption influence factors can be analyzed and the future energy consumption conditions can be predicted, thereby providing reference for energy conservation measures of tramcar systems.

Description

technical field [0001] The invention belongs to the technical field of energy consumption analysis of a tram system, and in particular relates to a method for analyzing energy consumption of a tram system based on a control chart. Background technique [0002] With the continuous improvement of my country's urbanization rate, the pressure of urban traffic has gradually become prominent. In order to alleviate this pressure, public transportation such as subways and trams have gradually taken the lead in urban transportation. However, due to the long construction period of subways, The investment cost is relatively high, so the current subway construction in my country is limited to a few large cities, and the problems of traffic congestion and "travel difficulty" in medium-sized cities are still difficult to solve. Tram has gradually become a means of transportation in large and medium-sized cities due to its many advantages such as no pollution, safe operation, and little imp...

Problems solved by technology

[0004] The purpose of the present invention is to provide a tram system energy consumption analysis method based on the control chart, aiming at solving the problem that the existing tram system energy consumption analysis method in the above-mentioned background technology only affects each energy consumption when establishing a mathematical model Factors are analyzed independently, there is a lack of research and analysis on the correlation of influencing factors, the potential relationship between energy consumption data cannot be obtained, it is difficult to conduct in-depth analysis of data, and there is also a lack of problems in the classification of energy consumption patterns and the identification and analysis of abnormal energy consumption data
