“…According to this definition, the coefficient D should include the electric damping and the mechanical damping. Because the mechanical damping is hard to calculate and is ignored, therefore, the D is only the electric damping, which can be calculated by follow equation given in [1].…”

“…The damping coefficient D in traditional generator model is an important parameter to impact stability of generator and power systems. Several of calculation equations of the D have been derived based on the equivalent circuit of generator or Park equation in [1]. But, when the generator is connected with other equipments, the damping characteristics of system will be changed, and its role is equivalent to adding an additional damping in original generator [2][3][4][5][6].…”

The change of mechanical torque is usually ignored in small disturbance of power systems, which means that influences of the hydro turbine and governor system (HTGS) have been ignored. The disturbance characteristics of the hydro turbine generating units including the HTGS is studied based on torque coefficients method in this paper, and calculating method and expressions of torque coefficients of the HTGS are given. The additional mechanical damping produced by the HTGS can be expressed as DtΔω, therefore, it can be merged into the damping item in the motion equation of generator, that means that its action is equivalent to modify damping coefficient D. Using a case, the analysis and calculation method are introduced, and several conclusions are given.
