Abstract

Abstract:

To solve the problem that the doubly fed adjustable speed pumped storage unit with speed as control target cannot participate in the primary frequency modulation of power grid, this paper proposed a kind of coordinated control of doubly fed adjustable speed pumped storage unit and pump turbine for primary frequency modulation. The mathematical models of pump turbine and doubly fed induction machine are established, and the process of speed optimization of doubly fed induction machine is analyzed according to the efficiency characteristic curve of pump turbine. By adding frequency controller to the speed control of doubly fed induction machine and guide vane opening control of pump turbine separately, the grid frequency deviation is tuned as additional command for speed control and guide vane opening control. Moreover, the influence of frequency controller parameters on the frequency modulation performance of doubly fed adjustable speed pumped storage unit are analyzed. The simulation results show that the doubly fed adjustable speed pumped storage unit can absorb or release energy in short term by adjusting the speed to reduce the amplitude of frequency fluctuation at the beginning of frequency fluctuation. And the mechanical torque of pump turbine is changed by controling the opening of guide vane, and then the output power is adjusted to reduce the steady-state deviation of gird frequency in later period.
