- Fundamental theory of forced power oscillation in power system
电力系统强迫功率振荡的基础理论 - By applying dwt and mallat in wavelet analysis , the oscillation signal of active power on transmission line is decomposed and reconstructed ; the strategy of upfc ' s secondary control based on wavelet is proposed by using the reconstructed active power as input signal . simulation results verify the efficiency of damping subsequent swing quickly under serious power oscillation circumstance that is hard to damp by ordinary upfc controller . the system dynamic stability is apparently enhanced
针对系统功率波动频率较高情况下upfc对系统后续摆稳定的控制作用难以得到充分发挥的情况，采用小波分析的mallat塔式算法对系统功率波动信号进行分解，并基于mallat塔式重构算法的思想滤除了信号的冗余扰动成份，寻找到一个高压缩比、低相对误差的重构功率信号，从而使其能够符合upfc实际控制需要。 - Because central potentials of four y windings in 12 - phase generator are not equal each other and there is no common reference inside the generator , it is difficult to identify the on / off of rectifying elements . in this paper , by using a mathematical model with line voltage substitute for phase voltage , the problem that there is no common reference in the 12 - phase generator with rectifier is solved . based on results of the studies on small prototype , 920kw charging generator applied in a submarine is improved in design , and therefore power oscillation with high magnitude when two generators are operating in parallel
由于十二相发电机中四个y绕组的中点电位不等，电机内部没有公共参考点，从而在判断整流元件导通时，不能象三相同步发电机整流系统那样认为阳极电位最高或阴极电位最低的整流元件导通，本文采用了以线电压代替相电压建立十二相整流发电机的数学模型，从而解决了十二相发电机无公共参考点的问题。
