Abstract


There are only two stable state in the traditional distribution network for Static Synchronous Compensator (D_STATCOM), that is inductive reactive and capacitive reactive power state. Although the phase angle and amplitude of the output voltage can be controlled, with the absence of active capacity, in the steady-state, the phase angle and amplitude can not be adjusted independently. Therefore, it is not possible to change the active power and reactive power at the same time.However, the output voltage of the Shunt Dynamic Voltage Regulators ( SDVR ) is completely controllable, so it can provide the AC current which was arbitrary phase angle with the system voltage phasor , this can make SDVR be issued / absorded active power and reactive power in the four quadrants, and the control of active power and reactive power is independent.This article first introduced the working elements of SDVR , deeply analysised the working features of SDVR, and set up the voltage converter of SDVR in the three-phase static coordinate system and two-phase synchronous rotating coordinate system (d, q) of the mathematical model through the equivalent circuit model of the system. On this basis, the operating characteristics with the DC-side and AC-side of the voltage converter for SDVR was further analysisedSecondly, this article analyzed the three-phase voltage converter states feedback decoupled control programs of SDVR, as well as its design method of the current inner-loop control system and voltage outer-loop control system in Chapter III.Finally, according to the SDVR block diagram and its converter circuit model, this article used the Power System Module of Simulink in the simulation software MATLAB R2008a to establish the SDVR simulation model in 380V voltage .Then detailed analysised the simulation results with SDVR or not in the five conditions for the system increases, sudden load reduction, under-voltage power grid, power grid over-voltage, voltage fluctuations and supply disruptions.
