Abstract: The steam turbine unit is closely related to the power system low frequency oscillation. The classification, mechanism and locating methods for power system low frequency oscillations are presented in details from the aspect of the steam turbine unit. Then, specific measures to restrain the low frequency oscillation are proposed from the power generation side in terms of control logic optimization, strict testing as well as quick and correct operation procedures. At last, suggestions on power grid coordination are put forward, such as the control logic optimization and strict field testing, to improve the power grid security and stability level.

Key words: steam turbine, turbine governor, power system, low frequency oscillation, steam turbine flow characteristics, primary frequency regulation
