The joint effect of active and reactive power on the voltage stability of a typical power system was considered by analysing the two parameter bifurcation problem related to nonlinear oscillation phenomena. Numerically, as the active power P1 increases, the Hopf points get closer and eventually coincide at P1=1.455 43 the cyclic fold curve gets closer and closer to the Hopf curve and finally intersects the Hopf curve at a singular point the period-doubling points also get closer and finally coincide at P1≈0.65. The stability behaviour is pre-determined using the normal form approach near the limit point of the Hopf curve. Hence, in the power system attention should be paid to both the consumption of active power and the decrease in the reactive power to prevent nonlinear oscillations. A controller can be designed to absorb some active power and to avoid the nonlinear oscillations that damage the system components.

针对一个典型的单机无穷大电力系统，通过分析系统的双参数分岔的非线性振荡现象，综合考虑有功和无功功率对电压稳定性的影响数值分析表明，随着有功功率的增加，电力系统的Hopf点越来越靠近，最终合为一点在P1=1.455 43处同时圈折cyclic fold 曲线也越来越靠近Hopf曲线，并在Hopf曲线的稳定与不稳定临界点处与Hopf曲线相交倍周期分岔点也随着越来越靠近，最终在P1≈0.65 合为一点应用正规形理论方法，初步确定了Hopf曲线极限点附近的稳定性态因而，电力系统应注意让负荷利用有功功率，减少无功功率的产生以防止非线性振荡另外，可以设计一个稍微吸收网络的有功功率的控制器，以避免因周期振荡而造成电力系统仪器的损坏或电压崩溃

In the same way, the reason why the British politicians now in England find it difficult to govern Ireland and India, is because modern Englishmen today do not know that it was not British democracy, the British Constitution or Parliamentarism, but the British or English civilization with the "gentleman" and its ideal; in short, that it was not the British mob, but the British or English gentleman who built up the great British Empire of today. But that is neither here nor there.

同样，不列颠"无名战士"，新近葬入英国西敏寺，驱走恶魔，封建德国狂怒之条顿人，目今英国之不列颠政客，之所以觉爱尔兰及印度难治者，盖因今日现代英国人不知，今日大不列颠帝国之所以成者，既非不列颠之民主、亦非不列颠之政体或议会制度，而乃不列颠或英格兰文明蕴有"温良"及其理想之故也；简言之，今日大不列颠帝国之所以成者，非不列颠群氓之功，而乃不列颠或英格兰温良秉性之士之功也。
