Gaoya dianqi新能源出力所具有的高维性和不确定性制约了配电网对新能源的消纳能力，故需在配电网规划环节中充分考虑调度周期内各天各时段的新能源出力情况。为此，以典型场景集作为模拟运行场景，设计了一种计及源荷出力不确定性的配电网多目标随机规划方法：首先采用K-means聚类算法将历史场景聚为K种日状态类型，并得到相应概率分布；其次以日状态类型为条件，结合基于SN-CWGAN的场景生成方法生成考虑源荷高维相关性的场景集；进一步，构建配电网多目标两阶段随机规划模型，其中上层实现储能选址定容与新能源规划 ...

Dianci bileiqi胶浸纸穿墙套管是直流输电工程换流站直流场与阀厅的连接设备，运行条件严酷，需要长期承受机、电、热等多种应力作用，其可靠性对系统安全至关重要。胶浸纸穿墙套管是典型的长悬臂结构，机械应力集中更加突出，因此其重负荷下的绝缘性能研究具有重要意义。国内外现行标准均开展单因素试验考核，与实际多因素工况存在一定差异，尚未见有关直流穿墙套管多因素试验研究的报道。本研究以某典型胶浸纸直流穿墙套管缩比单元电容芯体为研究对象，重点开展重负荷状态下电容芯体的绝缘性能测试。试验数据表明未加悬臂负荷时局部放电合格的电容芯体 ...

Gaoya dianqi油浸式铁心电抗器正常运行期间其振动由绕组受力、铁心磁致伸缩效应以及铁心饼间的麦克斯韦力导致。通过构建电抗器磁—固耦合三维模型，对电抗器在3种载荷作用下的轴向及径向振动响应分布进行分析。在此基础上搭建电抗器振动试验平台获取了电抗器箱体振动信号，通过调整铁心轴向压紧力，对箱体振动信号进行采集，通过提取各机械状态下的振动频谱特征可知，随着电抗器铁心轴向压紧力降低，箱体振动信号频谱发生变化，采用3种贝叶斯优化的网络分类器模型，对不同压紧力下的机械状态进行识别，准确率分别达到了94.5%、94.2%与95.0 ...
