考虑等效阻抗影响的对称双芯移相变压器仿真建模研究

Gaoya dianqi
随着新能源渗透率的不断提高，配电网合环不停电转供逐渐成为研究热点，移相变压器（phase shifting transformer，PST）作为重要的潮流调节手段受到广泛关注。在现有对PST的建模与计算方法中，往往忽略等效阻抗对移相效果的影响，导致在某些情况下的分析结果与实际情况存在偏差，影响系统安全稳定运行。为此，文中考虑了移相变压器功能的多样性以及结构的多变性，计及等效阻抗产生的电压降，建立了考虑等效阻抗影响的双芯对称型移相变压器模型，并且推导出相应的潮流计算模型，使得理论分析的结果更加准确 ...

高土壤电阻率山区输电管廊接地特性研究

Dianci bileiqi
管廊输电在解决新能源外送难题中具有重要意义，其接地系统关系到设备安全运行。本研究使用CDEGS建模，系统分析了土壤电阻率、管廊长度及贯通地线与主结构钢筋的跨接距离对接地系统电气特性的影响。结果表明，土壤电阻率升高导致接地阻抗线性增加，在短管廊中增速更快；管廊长度增加可逐渐降低接地阻抗，但当管廊长度超过4 km后，降阻效果不再明显；缩短贯通地线与主结构钢筋的跨接距离能有效降低接地阻抗，其中100~125 m的跨接距离较适宜。综合对比管廊人工与盾构接地系统的电气特性，发现在高土壤电阻率长距离输电环境下 ...
