In this paper, NERC (North American Reliability Council) records of power system disturbances for the year 1984 through 1999 are explored. The disturbance sizes show a power law distribution which confirms the early results [2] . Further, we find that the probability density of time intervals between disturbances can be given an exponential fit. Based on this observation, the suitability of applying SWV analysis to power system disturbances data is questioned. An artificial time series is

Some initial simulation results are shown to be consistent with NERC data. Besides SOC and HOT, this model gives another way to investigate power law behavior in power system disturbances. 0-7695-
