发布时间：2018-11-08 19:44
【摘要】：PSS4B是一种新型的多频段电力系统稳定器,因能同时抑制多个振荡模式且设置更加灵活而具有广泛的应用前景,但PSS4B参数整定相对复杂,目前相关的研究还比较少。按实际应用要求,在系统多运行方式下,用相位补偿法整定超前滞后环节的时间常数,用根轨迹法确定增益;在概率特征根分析的基础上,部分计及PSS相互间的影响,使用概率灵敏度分析法进行分析。由此进行的PSS4B参数整定,将使PSS4B在多运行方式下充分发挥优势。在一8机24节点系统上进行分析,结果表明安装的6台PSS4B均能提供对关注的振荡模式的有效阻尼,具有较强的适应性和通用性。
[Abstract]:PSS4B is a new type of multi-band power system stabilizer, which has a wide application prospect because of its ability to suppress multiple oscillation modes at the same time and to set more flexibly. However, the tuning of PSS4B parameters is relatively complex, and there are few related researches at present. According to the practical application requirements, the phase compensation method is used to set the time constant of the lead-lag link, and the root locus method is used to determine the gain under the multi-operation mode of the system. On the basis of probabilistic eigenvalue analysis, the probabilistic sensitivity analysis method is used to analyze the influence of PSS on each other. The tuning of PSS4B parameters will make PSS4B give full play to its advantages in multi-operation mode. The results of analysis on an 8-machine 24-bus system show that all of the six PSS4B can provide an effective damping to the concerned oscillation mode and have strong adaptability and versatility.
