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.
