Analysis of D-STATCOM Reducing Loss and Saving Energy in Distribution System Based on PSCAD

According to requirement of the energy conservation of the distribution system, this paper analyses the principle of D-STATCOM reducing Loss and saving energy in distribution system, from the point of reactive power compensation and harmonic filtering in this article from no point of view. Based on instantaneous reactive power theory, a control strategy for the D-STATCOM voltage bridge circuit designed, to use D-STATCOM the purpose to improve the distribution network power factor. The effectiveness and good operating performance of the device and control strategy are certified by simulation with PSCAD/ EMTDC, filtering out the harmonics and compensating reactive power, so as to achieve the purpose of energy conservation Loss Reduction.
