金属氧化物避雷器的过电压通流能力和热稳定性

Dianci bileiqi, 1985
对金属氧化物避雷器的过电压通流能力和热稳定性能进行了实验研究。已经发现,对不同峰值和持续时间的操作过电压和暂态过电压的击穿能量大致相同。对84千伏瓷套式避雷器试样的散热能力进行了试验,发现其散热能力小于小型模拟元件的散热能力,其数值关系在前所发表的文章中已讨论过。根据这些试验数据发现,运行电压高低的极限不是由通流能力决定,而是由热稳定性能所决定。

基于日照辨识的输电线载流能力评估

Gaoya dianqi, 2013
输电线路的输送能力将直接影响发电和用电水平,因此如何提高线路载流能力得到广泛关注。由于线路沿途进行日照条件测量成本高且可靠性难以保障,使得动态计算输电线载流能力的方法难以得到广泛应用。笔者提出通过利用在线温度信息和线路实时电流信息,辨识日照参数,获取线路载流量计算所需的日照参数,以实现线路实时载流能力的评估。仿真分析证明,该方法能有效地在线预测输电线最大载流能力,为充分利用线路输电能力、保障可靠供电提供参考依据。
