Abstract

The self-restoration ability in the power system following a temporary fault has become an attention since its contribution to the power system stability. The aim of this study is to analyze the impact of the auto reclose on the transmission line on a radial network stability by using the leader-follower control scheme. The leader-follower control scheme is used to minimize the outage time and to reduce the stress on one of the circuit breakers due to closing on permanent fault. This study is applied to a case of an electrical transmission system 150 kV in Gorontalo Province, Indonesia. Currently, the power transmission system in Gorontalo Province has not applied an auto reclosing scheme yet. This study is simulated in order to provide a stability assessment of: the rotor angle, rotor speed, active and reactive power in line transmission, current flow in line transmission, the voltage on bus, and the frequency on bus. The result of this study indicates that a significant voltage drop occurs on one of the bus in the network following fault.

引导者-从动器自动合闸对提高输电系统稳定性的影响

电力系统暂态故障后的自恢复能力关系到电力系统的稳定，因此受到人们的关注。本研究的目的是利用引导者-从动者控制方案，分析输电线路自动合闸对径向网络稳定性的影响。采用先导从动控制方案，最大限度地减少停机时间，并减少由于永久故障合闸对断路器的压力。本研究应用于印度尼西亚Gorontalo省150千伏电力传输系统的一个案例。目前，Gorontalo省的输电系统尚未采用自动重合闸方案。为了对转子角度、转子转速、线传有功功率和无功功率、线传电流、母线电压和母线频率的稳定性进行仿真。研究结果表明，故障发生后，网络中有一条母线会出现明显的电压降。
