    Abstract: In order to improve the operational efficiency and stability of distribution grid system, this paper carried out prediction and analysis for distribution grid feeder load, based on the establishment of auto-regressive and moving average (ARMA) model. The distribution grid feeder load data series and the ARMA model were established to analyze the difference operation, standardization, autocorrelation coefficient and partial correlation coefficient of feeder load data series. The ARMA model was adopted to predict the distribution grid feeder load data series in certain period of time. The analysis results of calculation examples show that the prediction value of the ARMA model conforms to the actual value.
    Key words: distribution grid; feeder load forecasting; data series; auto-regressive and moving average model
