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 process of power relationship adjustment and deployment, the original administrative power order has been shattered, but yet the new order has not been completely established. Thus the administrative power system is disordered: public power is departmentalized, department power is individualized, personal rights are commercialized and the benefits of all power bodies are contradictive, which are the secondary factors against modernization in the process of administration.
在这一系列的权力关系的调整和配置过程中,原有的行政权力秩序被打破,但新的行政权力秩序并没有完全建立,因此形成了行政权力体系的失序,出现了公共权力部门化,部门权力商品化和各种权力主体的利益冲突等现象。
