Modern tramcar hybrid energy storage system energy management method based on working condition analysis

Abstract

The invention relates to a modern tramcar hybrid energy storage system energy management method based on working condition analysis, and the method comprises the steps: 1), carrying out the arrangement of historical data obtained in the operation of a tramcar, dividing the historical data into short strokes, screening the short strokes meeting conditions, enabling the screened short strokes to enter an alternative stroke library, and deleting the short strokes which do not meet the conditions; 2) extracting characteristic values of each short stroke, and screening 13 characteristic values; 3) carrying out dimension reduction on the characteristic value by using a principal component analysis method; 4) using a clustering analysis method to classify the operation conditions; 5) performing online identification on the actual operation condition by using a learning vectorization neural network; and 6) based on the identified working conditions, performing classification optimization on the energy management method under each working condition. According to the invention, the electrical energy-saving purpose of rail transit can be achieved. The energy management strategy is optimized based on the working condition analysis result, classification optimization can be carried out according to different modes of vehicle operation, and the optimization effect of the energy management strategy in each mode is improved.

Description

technical field [0001] The invention relates to the field of rail transportation. Background technique [0002] With the continuous shortage of energy resources, the rapid development of rail transit has an increasing demand for electric energy. At the same time, following the trend of energy conservation and emission reduction, the application of energy storage technology in the field of rail transit has become a research hotspot in recent years. At present, the oversaturation of population in the central urban area is common in large cities in my country. The urban spatial structure generally develops from single center to multi-center. The traffic demand between the central urban area and the peripheral new cities is increasing rapidly. appears to be very important. With its significant advantages such as large capacity, fast speed, safety and reliability, punctuality and comfort, low energy consumption, less land use and less pollution, urban rail transit is bound to bec...
