Application simulation study on D-FACTS in military supplication system

Firstly,the principle of DSTATCOM was explained in three-phase three wire system.Secondly,the equivalent system achieved digitally much easier was constructed by adopting line voltage to control and compute and the method overcame the shortcoming of α-β reference frame in three-phase three wire system.The control system scheme was given.Finally,the system model was built up using PSCAD/EMTDC software.The experiment results show that DSTATCOM is effective in improving harmonic current,transient power quality and keeping system voltage stable.At the same time,the prospective application of DSTATCOM in military power system was discussed.
