[Abstract]:The static synchronous compensator D-STATCOMcan effectively solve the voltage fluctuation problem in distribution network. In this paper, a D-STATCOM device and its DSP controller are developed for three-phase balanced distribution system, and applied to voltage stability control of battery charging and discharging system. Based on the mathematical modeling of D-STATCOM circuit, the stability of the system is analyzed by using the Rouse criterion, which shows that the D-STATCOM system is controllable. The principle of D-STATCOM voltage stabilization is analyzed, and the feasibility of voltage stabilization scheme is verified by simulation. On this basis, the hardware and software design of D-STATCOM voltage regulator is emphasized. The hardware design mainly includes IGBT photoelectric isolation and drive, signal conditioning, fault protection, PWM output buffer, control power supply, relay protection, etc. The software design mainly includes initialization AD sampling and control algorithm, etc. The closed loop running test is also carried out. On this basis, the D-STATCOM battery charge and discharge-reactive power stable experimental prototype. The structure of the main circuit and the selection of the device parameters are analyzed, and the overall control algorithm of the system is studied. Under the conditions provided by the laboratory, the D-STATCOM reactive power steady voltage system experiment is done, and the experimental results are analyzed in detail. The results show that the D-STATCOM device can keep the AC bus voltage of the battery charging and discharging system stable.
