Abstract


This paper studies the characteristics of dynamic voltage drop in the grid voltage three-phase equilibrium system in the case based dynamic simulation of the flexible flywheel energy storage power conditioner (FPC) . Major research in grid voltage three-phase equilibrium response of the system voltage drop occurs , its main goal is to improve control strategies to suppression grid voltage drop given rotor overcurrent guarantee the FPC in grid voltage drop is not off-grid At the same time , the reactive power delivered to the grid , in order to ensure the stability of the grid voltage . In addition, on the basis of the previous single machine infinite bus system under small perturbation experiment by experimental verification FPC has the ability to inhibit system small amplitude power oscillations . The whole system in order to get the system control strategy in the grid voltage drop in the run state voltage drop case detailed analysis. The second chapter is to establish the model of double-fed motor rotating coordinate system , and leads to the traditional vector control technology . The third chapter near the coping strategies of the grid-side converter ( network side converter ) in the case of grid voltage drop , and gives the simulation results in MATLAB / SIMULINK . Chapter IV , as the focus of this dissertation chapters of the voltage drop doubly fed a careful study of the dynamic characteristics of the motor , and analyzes the voltage drop when the motor stator and rotor overcurrent close to the rotor , and on this basis to study side of the converter (the rotor side converter ) and the interaction between the motor , there is proposed a new control strategy to reduce the voltage drop , when the fixed rotor-side overcurrent . PSCAD / EMTDC simulation waveforms , and verify the effectiveness of the control strategy is given at the end of this chapter . The last chapter gives the FPC steady-state case , direct frequency conversion , energy storage , power generation, phase modulation , and transient small perturbation experiment experimental waveform , experimental results prove , FPC have the ability to inhibit the magnitude of the power grid small and medium-sized power oscillation .
