stationary term meaning in English
定常顶
Examples
- When the load of agriculture and illume is forecasted , the load is decomposed into stationary terms that is not related to meteorologic factors and random term that is related to meteorologic factors by use of wavelet analysis . because the forecasting accuracy of stationary term is higher and the amplitude of random term , although it is difficult to forecast , is smaller , so the impact of forecasting error bringing about by random factors on final forecasting result is weakened
在预测不同行业的负荷时,利用小波分析的方法对农业和照明负荷序列进行分解,然后将频率较低的部分视为与气象因素无关的稳定项进行处理,将频率较高的部分视为与气象因素相关的随机项进行处理,由于稳定项预测精度高,随机项虽较难预测但幅值较小,因此削弱了随机因素带来的预测误差对最终结果的影响。
