Abstract | To improve the voltage quality of the power supply is an important function of the D-STATCOM. A novel voltage control strategy based on active-disturbance rejection control under unbalance voltage conditions is proposed in this paper. The active-disturbance rejection control for D-STATCOM is proposed to overcome the difficulty result from the nonlinear, multivariable and coupling characteristics of D-STATCOM and the uncertainty parameters of the model of D-STATCOM along with the uncertainty disturbance in the engineer application. The magnitude and unbalance degree of the voltage of Point of Common Coupling (PCC) can meet the national voltage supply standard through the use of controller structure with superposition of positive-negative voltage control loop. Furthermore the controller has excellent performance for example good adaptive and robust when the parameters changes and the disturbance occur. Under MATLAB/Simulink environment, the model of D-STATCOM system is built and the simulation result is given. The simulation results verified the correct and effectiveness of the control strategy proposed in this paper. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
