The real wind speed datum of wind farms in Northeast China are analyzed.The same hourly wind speed of the month in the years obeys a Weibull distribution.The actual wind speed series and the time-series of regression analysis model are connected by probability measure transformation.The model of a single wind farm wind speed is built by autoregressive moving average（ARMA）model，and multi-wind speed model built by vector auto regression（VAR）model.The detailed model parameters are shown.The actual wind speed data and simulated wind speed time series have a better consistence.The simulated wind speed time series based on the probability measure transformation are feasible and effective.
