摘要
用时间序列分析中的自适应滤波预测法,建立某市用电量的预测模型,得到了用电量发展变化的规律;对模型从几个方面进行了分析并与电量预测常用的指数平滑法和灰色法进行了对比,结果表明自适应滤波法适合用于城市电量预测并可认为是一种较好的方法。
Based on the forecast method of adaptive filter,a forecasting model for city's electric engrgy demand is developed in this paper.By using the model,the variation rule of electric energy demand for the city is obtained.Some analyses on the model and a comparison among adaptive filter method,exponentially moving average method and grey system forecast method are given out.The study exposes the adaptive filter method is a better forecast method for city's electrie energy demand.
