Abstract

To increase the transmission capacity of remote high voltage transmission system, the series capacitance compensation of power network is a very economical and effective common measure. But, when electric power system is connected in series with the power transmission system of capacitance compensation and after the system is disturbed under equilibrium state, electric power system may exchange considerable energy with steam turbine generator units with one or several natural frequencies which are lower than synchronizing frequency. Such a phenomenon is called as sub-synchronous resonance (SSR). Under sub-synchronous resonance, inner of generator will create sub-synchronous rotating magnetic field which interacts with synchronous rotating magnetic field forming slip frequency vibration torque. There may be resonance between mechanical and electric systems damaging the axis system of generator. Therefore, it is a worthy topic to study how to restrain the sub-synchronous resonance after compensation of electric power system in series connection.
