Gaoya dianqi配电系统正在朝着三相负荷消耗愈加不平衡的方向发展，三相负荷不平衡会显著增加三相电压不平衡，进一步影响三相配网节点电价DLMP（distribution locational marginal price）。此外，过大的电压不平衡将会对配电网和用户设备造成巨大的危害。配网中的居民暖通空调（heating，ventilation and air conditioner，HVAC）负荷因其热惯性，在用电行为上具有较大的灵活性，有助于缓解配网三相电压和DLMP的不平衡。对此 ...

Gaoya dianqi基于电网换相换流器的高压直流（LCC-HVDC）输电系统中的交联聚乙烯（XLPE）电缆绝缘在实际工况下不仅长期承受内高外低的温度梯度作用，还要面临潮流反转调整，承受极性反转电场，严重影响着XLPE绝缘性能。为此，基于双极性电荷输运模型仿真研究了温度梯度和极性反转条件对XLPE中空间电荷动态特性及电场畸变的影响。结果表明：温度梯度增大，高温侧附近同极性电荷增多，这部分残留电荷在电压反转后表现为异极性电荷，增强了此处场强；常温下电压极性反转越快，残留电荷越多，反转后最大电场越高，而温度梯度下极性反转越快 ...

Dianci bileiqi, 1990 提出了保护矿井中的变压器和配电电器的雷电避雷器系统。环形配电网路通常在接总负荷的中心处附近断开。地下（电缆）网路接到架空线的情况和装在矿井中的变压器的间隙接入增大了电网受雷电过电压损坏的概率,绘出了雷电避雷器结构的示意图 ...
