基于CEEMD和GRU的电力变压器材料价格预测OACSTPCDEI
Price prediction of power transformer materials based on CEEMD and GRU
中国经济的快速增长推动了电网的扩张.电力变压器是电网工程中的关键设备,其价格变化对造价控制有着重大影响.然而,电力变压器材料价格表现为非平稳和非线性的序列.因此,电网工程的设备购置费估算困难,阻碍了电力工程的正常建设.为了更准确地预测电力变压器材料价格,本研究提出了一种基于互补集合经验模态分解（CEEMD）和门控循环单元（GRU）网络的方法.首先,CEEMD 将价格序列分解为多个固有模态函数（IMF）.根据每个 IMF 的样本熵,对多个 IMF …查看全部>>
The rapid growth of the Chinese economy has fueled the expansion of power grids.Power transformers are key equipment in power grid projects,and their price changes have a significant impact on cost control.However,the prices of power transformer materials manifest as nonsmooth and nonlinear sequences.Hence,estimating the acquisition costs of power grid projects is difficult,hindering the normal operation of power engineering construction.To more accurately p…查看全部>>
