基于CFD模拟的全户内模块化变电站室内通风散热及气流组织优化设计
Gaoya dianqi全户内模块化110 kV智能变电站因其室内空间有限、电气设备发热集中，在实际运行中暴露出室内平均温度较高、局部温度过高、温湿度控制难度大等问题，不利于电气设备的高效安全运行。因此，文中通过控制进、出风口参数改善室内通风散热和气流组织效果，首先分析了变电站标准化设计与装配式建设中通风散热现状及电气设备发热情况；然后，基于真实情况建立了变电站整体三维物理模型，对温度场分布、气流组织分布等进行仿真模拟。数值模拟结果显示，室内平均温度为48℃，高于110-A2-6设计方案中室内温度设计要求 ...

Gaoya dianqi高压直流换流阀饱和电抗器在工作过程中发热量大、电场分布不均匀，使其成为阀厅的安全隐患。为改善饱和电抗器的温升效应，文中以实际±500 kV直流换流阀用饱和电抗器为研究对象，建立了改进的流体场与温度场耦合模型，该仿真模型综合考虑流体传热、空气对流散热、绕组焦耳热和铁心涡流热损耗等实际因素，仿真计算电抗器各部件的温度场分布及其影响因素。现场验证表明该模型计算结果更接近实际工作状况。还建立静电场仿真模型，仿真计算电场畸变情况。温度场结果表明：饱和电抗器的铁心温度最高、环氧树脂次之、冷却水管路温度最低 ...
