摘要
不同期合闸产生的过电压比同期合闸产生的约高出20～39％,对电力系统的危害更加严重。本文继续探索不同期合闸诱发高过电压的内因。 一、延滞型微分方程 描述三相不同期合闸的数学模型为具有常时滞的延滞型非线性泛函微分方程:
As a continuation of our previous research this paper puts the stress on numerical simulation of tigher overvoltage induced by nonsynchronous closing. Main result as follow: Because of ordinary differential equation which is the mathematical model of preceding closing phases has two large harmonic solutions, so it implys possibility transformed from little harmonic solution to large one. Lagging currents i1 (t-τ1), i2(t-τ1) play an important role to help intensify the billows and Waves in this transformation process.
