| 摘 要： | 给出了达到无功越限后，可能出现极限诱导分岔的条件；提出了变量达到输出极限导致极限诱导分岔时，影响系统电压稳定与否的判据；给出了极限诱导分岔影响电压稳定的一种机理解释。极限诱导分岔反映了动态无功源在维持系统电压稳定性中的重要性，并研究了增加无功源对极限诱导分岔的影响。数字仿真结果进一步验证了文中所提出方法和机理解释的正确...

| Abstract: | Limit induced bifurcation(LIB),which occurs while reactive power output of generators exceeds the limit or output of dynamic reactive power sources is over-limited,is very dangerous to power system voltage stability.The conditions by which LIB may occurs is given while reactive power is over-limited;a criterion to judge whether voltage stability can be maintained is proposed while LIB occurs due to over-limited reactive power,and an explanation on the mechanism of how LIB influencing voltage stability is gi... |
