  2. 2. Abstract • This project presents and discusses a phase shifted- PWM distribution static synchronous compensator (D-STATCOM) using the modular multilevel cascade converter based on single-star bridge cells (MMCC-SSBC). • An analytical model for the phase-shifted PWM is proposed to design the current control gains. • Two phase-shifted PWM methods, which are named as one-cell and all-cells update methods, are theoretically and experimentally compared. www.iistechnologies.in Ph: 9952077540

  4. 4. Existing System • Among the MMCC family members, the SSBC is the most basic and suitable for the static synchronous compensator (STATCOM). • An SSBC-based STATCOM yields three-phase multilevel voltage waveforms with low voltage steps. • This results in requiring no shunt harmonic filter at the ac side of the STATCOM. Moreover, the modularity facilitates an eventual expansion of cascaded bridge cells. • As a result, when it is applied to power distribution systems with nominal voltages of 6.6 kV in Japan and 13.8 kV in the U.S., a reasonable compromise between the blocking voltage of switching devices and the cascaded bridge-cell count per cluster enables to eliminate a medium- voltage line-frequency transformer from the distribution STATCOM (also known as D-STATCOM). However, since the SSBC-based D STATCOM installs a split and floating dc capacitor on the dc side of each bridge cell, it is mandatory to keep all of the mean dc capacitor voltages regulated and balanced. www.iistechnologies.in Ph: 9952077540
  5. 5. Proposed System • This project achieves general modeling and analysis of current control in an SSBC-based D- STATCOM intended for a distribution system, considering a time delay caused by phase-shifted PWM. • As the bridge-cell count gets higher, the all-cells update method can reduce the time delay more significantly than the one-cell update method. • A three-phase downscaled SSBC-based D-STATCOM is designed, constructed, and tested to confirm the validity and effectiveness of the modeling, analysis, and design. The D-STATCOM consists of six cascaded bridge cells per cluster. • This project includes experimental comparisons in current control performance between the all cells and one-cell update methods. • Transient waveforms obtained from the experiment agree well with those from the computer simulation using a software package of PSCAD/ EMTDC. www.iistechnologies.in Ph: 9952077540
