In view of such issue as weak tracking accuracy of current detection and large load interference in the distribution static compensator（DSTATCOM for short）of split capacitive three-phase four-wire distribution network

in this paper

a novel current predictive control strategy with time delay compensation performance is proposed based on the deadbeat predictive strategy control algorithm

which can eliminate the compensation error due to control delay and

at the same time

omit dp rotation coordinate transformation in the traditional current predictive control algorithm and simplify the design process of the control system.Moreover

the selection of switch condition is achieved with help of 3-D space vector modulation technology so to keep the control system have fixed switch frequency

thus simplify design of filter inductance.Finally

the design of the controller is analyzed in detail

simulation and experiment are verified

which proves that adoption of the algorithm proposed is effective and feasible.
