Adaptive DC Stabilizer with reduced DC fault current for active distribution power system application by B.SWATHI16S45A0205 A.RAMYA16S45A0201 V.NAVEEN KUMAR 16S45A0234 D.PRASHANTH 14S41A0276 Under the guidence of Mr. K.Chandramouli Associate professor
ABSTRACT The main aim of the project is to control and
protection of medium power DC networks in an active distribution power system. By reducing the fault current System control Converter design In this to reduce the fault current and required converter current rating we are using adaptive dc stabilizer along with the reduced terminal capacitance and extra dc impedance.
In modern power system due to increase in the
power converter performance the dc power system is again used in power transmission and distribution. Dc power system a promising solution to connect large ac power grids and reconfigure medium voltage distribution power system. A common DC/AC converter in such systems can save one-off cost and possibly give rise to lower conversion loss.
In medium power distribution system the use
of micro grid along with multi pin AC/DC connections a future active distribution system is formed. For efficient operation and continuous current flow a dc network is connected between the two ac feeders. Fast acting DC circuit breakers can effectively isolate the fault with in a short period through with increase cost and conduction power loss.
Impedance matching based techniques were
developed to modify the small signal characteristics and the point of load from the source side control. Global system stabilization was proposed based on state space modeling to provide damping for bidirectional power flow. The proposed adaptive control is also independent from both the constant power terminal and the grid size conditions.
