Research on some problems about the test of power system stabilizer
Author(s): 
Pages: 23-25
Year: Issue:  3
Journal: ELECTRIC POWER

Keyword:  电力系统稳定器(PSS)试验励磁系统;
Abstract: 电力系统稳定器(PSS)是励磁系统的一种附加功能,它抽取与低频振荡有关的信号并对其加以处理.产生的附加信号迭加到励磁调节器中,使发电机产生阻尼低频振荡的附加转矩,用于提高电力系统的阻尼.将电力系统稳定器(PSS)投入运行是解决电网低频振荡问题、提高电网动态稳定性诸多措施中最简单、经济的方法.对山东电网电力系统稳定器(PSS)现场试验中出现的跳机、PSS模型不理想、阶跃试验发电机有功功率波动不明显等问题进行分析,提出试验前后屏蔽白噪声输入通道、在励磁调节器配置通用的PSS模型、优化励磁调节器PID参数等改进措施,以期对电力系统稳定器(PSS)的使用和现场试验有所帮助.
