英语语法分析

In case of low voltage and heavy load, the relay loadability may replace the thermal loadability, leading to undesirable relay operation and cascading events.

低压重载系统中，保护载荷度可能取代热载荷度，导致保护不合理动作以及后续连锁过程。

Of course, there is still many problems needed to be solved, but it is believed that the online transmission line loadability estimation will face a good prospect.

当然，尚有诸多工作尚需进一步深入研究，相信不久的将来，输电线路载荷定值的在线估计会有良好的应用前景。

This paper demonstrates the use of line stability index termed as fast voltage stability index (FVSI) in order to determine the bus maximum loadability in a power system.

介绍了使用线稳定指标作为快速电压稳定指标(FVSI)确定电力系统母线的最大承载负荷的方法。
