Research on the chaotic characteristics for heating load time series

In order to observe and study the possibility of the existence of chaotic behavior in the heating load, profound research has been performed at the real-test heating supplying load time series from 2007 to 2010 in this paper. Firstly, the data which were got from the worksite are pre-processed. Secondly, phase space reconstruction is done to the time series which have been processed. Thirdly, a qualitative, quantitative and RP analysis of data are accomplished. Finally, the rigorous chaotic character of the heating supplying load is found. This conclusion can provides evidence on the feasibility of introducing the chaotic control and prediction to the heating supplying system with the properties of large time-lag, nonlinear, time varying etc.
