Gaoya dianqi绝缘子沿面绝缘是直流GIS/GIL绝缘系统的薄弱环节，由于常规交流绝缘子设计准则不再适用于直流工况，研制新型直流GIS/GIL盆式绝缘子对提升直流管道装备可靠性具有重要意义。该研究将直流GIS/GIL中金属微粒的危险运动行为影响纳入管道电极表面场强控制范畴，明确绝缘子初始状态与直流叠加雷电冲击复合电压下沿面场强控制标准，并建立表面电荷积聚与复合电压耦合作用下绝缘子沿面场强考核模型。进一步提出基于表面轮廓曲线优化的直流盆式绝缘子设计方法，依托Bernstein方程开展绝缘子表面轮廓曲线重构 ...

基于反馈约束变分模态分解和LSTM网络的并联电抗器油温预测研究
Gaoya dianqi并联电抗器作为电网重要的电力设备，准确估计其油温变化趋势，可为早期故障监测和预警提供重要依据。提出一种基于反馈约束变分模态分解（VMD）和长短期记忆神经网络（LSTM）的并联电抗器油温预测模型；利用信号反馈约束和加权样本熵优化VMD分解个数k和惩罚因子α，形成VMDFS分解方法将并联电抗器原始油温序列分解成多组平稳的子序列，消除不平稳信息的影响；再对各子序列构建LSTM神经网络预测模型，用粒子群优化神经元个数；最后将各子序列预测油温叠加得到并联电抗器最终预测油温。通过对某变电站一台220 ...
