摘要
首先建立了一种求解电力系统小干扰电压稳定极限的数学模型,该模型考虑了从给定运行情况到极限运行情况的负荷增加过程中,发电机的有功变化、功率限制及有载调压变压器的分接头调整等因素。然后提出了该问题的实用简化求解方法,并给出了西北45机220节点系统的计算结果,表明所提算法既比现有方法更加符合实际情况,又具有较快的求解速度。
A mathematical model for determining power system smalldisturbance voltage stability limits is first presented in this paper, which takes into account all related factors such as OLTC action, generation variation and limitations. Then, a practical solution method based on predictorcorrector is proposed. Calculation results of 45generator 220bus Northwest system show that the proposed method is more reasonable and faster than the existing ones.
