摘要
分析了低频振荡建模的一般方法和特点,在研究单机无穷大系统中联络线低频振荡机理的基础上归纳总结了低频振荡模式的多机系统阻尼分配规律。在某8机系统算例中将阻尼分配规律与QR法相比较,分别得出的振荡模式实部之间只有微小的差别,验证了阻尼分析规律的正确性。
This paper analyzes the damping coupled phenomenon in single machine infinite system, and then through the analysis, deduces the multi-power machine systems damping apportionment rule of low frequency oscillation model and draws some valuable conclusions which are useful to restrain the low frequency oscillation of power system. Finally, the paper verifies the accuracy of the deduced damping apportionment rule by calculating a multi-machines power system.
