Gaoya dianqi为研究局部放电对油浸式电力设备绝缘劣化的影响，文中建立了油纸绝缘局部放电试验平台，探讨了局部放电电压和持续时间对绝缘纸损伤、绝缘油中游离碳含量及形态的影响。实验结果表明，局部放电电压和放电时间显著影响绝缘纸劣化和游离碳生成。通过外观形貌和图像分析发现，随着放电电压和时间的增加，绝缘纸表面碳化痕迹增多，损伤面积明显扩大。当放电电压从20 kV升至45 kV时，放电120 s后游离碳含量增加约50.88%，且碳颗粒尺寸显著增大。放电时间延长导致游离碳含量和颗粒尺寸增加，尤其在45 kV电压下 ...

Gaoya dianqi在对碳交易价格进行预测时，如何考虑在保证预测精度的同时提高预测效率是目前亟需解决的问题。针对该问题，文中考虑到现有预测方法中的碳价序列存在模态混叠问题和预测模型求解复杂的情况。从而提出一种基于VMD-LSSVM（variational mode decomposition-least squares support vector machine）的碳交易价格预测方法。首先，利用VMD算法将历史碳价样本序列分解为频率不同的碳价分量；其次，建立LSSVM模型并对分解后的各个碳价分量进行预测；最后 ...
