Abstract

The problem of subsynchronous resonance (SSR), which is not simp < strong>le for an interconnected multi-machine power system, is studied in this paper. The analytical approach that has been used for such a study is described in detail, and numerical examples are given bele 
A mathematical approach has been derived which calculates the electrical natural frequencies in an inter connected power systems. It shows the effects of various degrees of series compensation that are possible, together with the effects of alternative system parameters
This is necessary to determine the possibility of sy stem natural interaction with torque resonance. Series compensation can be considered at any level or omitted altogether.
