PSS现场投运试验及其相关问题的研究

PSS field test and its relevant problems

讲述了PSS基本原理及其作用,并以江西丰城发电厂1号机组为例,详细介绍了其现场试验过程,包括:AVR和PSS模型的建立;在线测量励磁系统频率响应特性测试;在线有补偿励磁系统频率响应特性仿真;PSS增益试验、阻尼效果校核及反调试验。并结合PSS在江西电网的实际应用,探讨了PSS在技术、管理等方面还需进一步完善的地方。

This paper introduced principles and functions of the PSS. With Fengcheng Power Plant No.1 unit as example, procedures of field test were presented including： AVR and PSS model establishment, frequency response test on on-line measurement excitation system, frequency response simulation of on-line compensation excitation system, PSS gain test, damping effect check and inverse regulating test. Combined PSS application in Jiangxi power network, the paper discussed improvements on PSS technology and management.
