摘要
性能优良的励磁调节系统配置电力系统稳定器(PSS)并合理地整定其参数,能有效地抑制电力系统低频振荡的发生。改进的PSS参数自动整定软件对提高电网的安全稳定分析水平、精确评估电网的暂态稳定水平均有很大的意义。针对自并励励磁系统、EX2100型励磁调节器为例进行了PSS软件设计以及对江苏省大唐吕四港电厂4号机新投运机组进行了实验,证明了改进的PSS自动整定软件的实用性及有效性。
High performance excitation control system with power system stabilizer （PSS） can be very effective in inhibiting the occurrence of low-frequency oscillation. The improved auto-tuning PSS software can improve the level of security and stability of the grid, highly evaluate transient stability of the level of the grid. In this paper a PSS software design has been implemented using a self-shunt excitation system and an EX2100-type excitation regulator as an example and experiment has been done by No. 4 generation unit in Jiangsu Datang Lvsi Power Plant to verify the software. The result showed the practicality and effectiveness of PSS auto-tuning software.
