| 摘 要： | 铁磁谐振是一种具有显著非线性动力特征的电磁现象.电力系统中存在着许多非线性元件,电力系统运行方式变化及系统设备的操作都可能激发铁磁谐振.它产生的长时间的过电压和过电流给电力系统安全带来巨大威胁.应用基础数学理论研究铁磁谐振可为其预防和抑制提供数学理论依据.为此,利用分岔图,相平面图等数学工具首次研究了并联金属氧化物避雷...

| Abstract: | By mathematic tools such as bifurcation map and phase map,the nonlinear dynamics of ferroresonance system with metal oxygen arresters(MOA) are studied.The effects of MOA on ferroresonance overvoltage,especially its chaotic characteristics,of neural grounded systems are analyzed.The results show the ferroresonance overvoltage can be inhibited and the chaotic ferroresonance can be transferred to non-chaotic one by installing MOA.And the range of parameter values for which chaos persists and the sensibility of... |
