A New Design Method of the One Order Electrical Load

摘要

In view of the current load simulator''s limitations of the dynamic characteristics and time-varying characteristics, this paper presents a new design method of the one order electrical load. The method switches the electrical load to simulate any one-order load within certain parameters by means of adjusting the load switch tube''s on-time and judges simulation degree on the load based on the load response curve''s “function distance” area''s the proportion in the load curve area within the unit cycle. For any given actual load, we used the cut-off frequency signal as input signal to simulate. The results show that load simulation degree was very high. Simulation results show that the one order load designed by using the method can simulate any one-order load within a certain range of parameters.
