| Abstract: | The emergence mechanism system is introduced in the paper of forced power low frequency oscillation of a 700 MW hydro-electric generator to power The similarities and essential differences between forced oscillation and low frequency oscillation with negative damping mechanism are described. The different inhibition effect and limitation of forced power low frequency oscillation in each frequency band are analyzed and verified theoretically. And it gets an experimental verification in giant hydro-electric units for the first time. The new monitoring identification and suppression method of the forced oscillation are put forward based on the engineering practice. The new proposed ideas and measures ensure the stable operation of power system. |
