Research and simulation of resonant earthed system Based on IPC [PDF]
, 2008 我国中压配电网，绝大多数采用中性点不接地方式。这种接地方式最大的优点是:当发生单相接地时，三相线电压的对称性没有被破坏，所以用户用电不受影响，可维持一定长的时间。但是，当配电网达到一定规模，对地电容电流达到一定数值后，必须采取加装消弧线圈的措施来保证配电网的安全。 配电网中性点采用消弧线圈接地的方式，对于改善电网供电质量、提高供电可靠性和保证整个系统安全运行都有十分重要的意义。本文在此背景下，对谐振接地系统展开研究与仿真。首先介绍了中性点接地方式的发展过程，通过对谐振接地原理和单相接地故障的分析 ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We
