Abstract

A change in load, switching operation, abrupt faults, and loss excitation are the causes of the transient disturbance. Therefore, it is crucial to regain synchronism or equilibrium upon disruptions to the electrical services. This paper focused on the analysis of transient stability of IEEE 9-bus system using Power World Simulator. The Newton-Raphson approach will be used during the load flow studies to determine the pre-fault conditions in the system. The system's variation in rotor angle, frequency, and voltage will then be investigated with the use of a three-phase balanced fault. It is concluded for different contingency test, there will be rotor deviation, changes in frequency and changes in voltage in per unit. Additionally, the critical clearing time of the system will vary depending on the contingencies test. Investigating the stability of the power system during abrupt and large disturbances is done using transient stability analysis, which is crucial to preserving the safety of power system operation.

基于电力世界模拟器的系统暂态稳定性分析

负荷变化、开关操作、突发故障和损耗励磁是引起暂态扰动的原因。因此，在电力服务中断时恢复同步或平衡是至关重要的。本文利用Power World模拟器对IEEE 9总线系统的暂态稳定性进行了分析。牛顿-拉夫森方法将在负荷流研究中使用，以确定系统中的故障前条件。系统的转子角度，频率和电压的变化，然后将使用三相平衡故障进行研究。结果表明，对于不同的偶然性试验，每台机组都会出现转子偏差、频率变化和电压变化。此外，系统的临界清除时间将根据应急测试而有所不同。利用暂态稳定分析方法研究电力系统在突发性和大扰动下的稳定性，对保障电力系统的安全运行至关重要。
