【摘要】 简要介绍了小干扰电压稳定和暂态电压稳定的分析方法,利用电力系统分析综合程序(WP- SASP6．1)和电力系统暂态安全定量分析软件(FASTEST1．0)对陕西电网分别进行了小干扰电压稳定性分析和暂态电压稳定性分析,两种方法得到的计算结论基本一致。通过计算,发现了陕西电网在电压稳定方面存在的一些问题和系统的薄弱环节,并提出了相应的电压稳定控制措施。更多还原

【Abstract】 This paper studies the voltage stability of Shaanxi power system. The small-disturbance voltage stability is analyzed through program WP-SASP6. 1, and the transient voltage stability is calculated by program FASTEST1. 0. The conclusions drawn by the two programs are similar. The latent problems of system operation and weak points of power grid are found out. On the basis of these conclusions, some solutions to improve voltage stability of Shaanxi power system are presented.更多还原
