优化LSSVM及其在电机故障诊断中的应用

Zhendong Ceshi yu Zhenduan
为实现异步电机在运行状态下快速准确诊断故障类型，构建了优化的最小二乘支持向量机（least squares support vector machine，简称LSSVM）智能故障诊断模型。首先，LSSVM将不等式约束改为等式约束，收敛速度更快；其次，改进粒子群优化算法（particle swarm optimization algorithm，简称PSO）在迭代过程设置1个粒子变异过程，随机放置的粒子可带领种群摆脱局部最优的束缚，找到全局最优点；最后 ...

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 ...
