In order to improve the power quality of distribution network system, one of the most effective methods is reactive power compensation. In this paper, the Distribution Static Synchronous Compensator for reactive power compensation was studied, and then the digital controller based on One-cycle control was designed. The waveforms of experimental device based on DSTATCOM of one-cycle control were given in this paper. It can be seen from the results that the fluctuation of DC capacitor voltage is lower, the dynamic response speed of DSTATCOM providing or absorbing reactive power is fast, and the accuracy of steady-state compensation can achieve the requirements of reactive power compensation in engineering basically

In the device, a four-post frame was adopted, two synchronously rotating grip holders were used to realize rigidity rotation of the specimen, and the axial movement of the upper grip holder implemented the tension/compression loading. Positioning accuracy in the axis, radial and circumferential directions were achieved by adopting many advanced and delicate technologies. Measurement on the device indicated that the actual positioning accuracy of the device was better than the kinematic positioning accuracy. Evaluation test on the system indicated that the spatial resolution is better than the pixel size without considering the noise.
