摘要

本文研究了Java-Bali子系统中由振荡引起的故障情况。利用电力系统仿真程序对故障情况进行仿真，以反映实际情况。利用proony方法对振动特性结果进行了分析。通过将振动波形分解为主导频率和阻尼比，分析了振动模态。通过改变发电机供电方向和电力系统稳定器(PSS)的设置来实现系统重构。对每次重新配置进行模拟，然后对结果进行分析，并将其与默认条件进行比较。仿真结果表明，通过将发电机组的方向重新配置到中java区域并激活发电机组的PSS，可以提高系统的稳定性。

Small Signal Stability Analysis as Impact of System Reconfiguration

Faulty condition caused by oscillation in a Java-Bali sub-system is investigated in this paper. The faulty condition is simulated by using power system simulation program to represent the real condition. The characteristic result of oscillation is analyzed by using the Prony method. The analysis of oscillation mode is done by decomposing the oscillation waveform into dominant frequency and damping ratio. System reconfigurations are developed by changing the generator supply direction and the setting of Power System Stabilizer (PSS). Each reconfiguration is simulated, and then the result is analyzed and compared to its default condition. Simulation result shows that by reconfiguring the direction of generation units to Middle-Java region and activating PSS of the generation unit can improve system stability.
