Voltage Sag/Swell are the most important Power quality issues which occur due to the utilization of increased number of sophisticated loads in Industrial and Electrical distribution system. Now-adays Industrial loads are generally based on Power electronic devices which are very sensitive to voltage disturbances. Hence it is mandatory to provide high quality power supply since; failures due to ...

Dynamic Voltage Restorer (DVR) restores the distribution system load voltage to a nominal balanced sinusoidal voltage, when the source voltage has distortions, sag/swell and unbalances. DVR has to inject a required amount of Volt-Amperes (VA) into the system to maintain a nominal balanced sinusoidal voltage at the load. Keeping the cost effectiveness of DVR, it is desirable to have a minimum VA...

AIMS We assessed regulation of volume-sensitive Cl(-) current (I(Cl,swell)) by endothelin-1 (ET-1) and characterized the signalling pathway responsible for its activation in rabbit atrial and ventricular myocytes. METHODS AND RESULTS ET-1 elicited I(Cl,swell) under isosmotic conditions. Outwardly rectified Cl(-) current was blocked by the I(Cl,swell)-selective inhibitor DCPIB or osmotic shrin...

Power quality is one of the major concerns in the present era. The problem of voltage sags and swells and its major impact on sensitive loads are well known. To solve this problem, custom power devices are used. One of those devices is the Dynamic Vol tage Restorer (DVR), which is one of the most efficient and effective modern custom power devices used in power distribution networks. A new cont...

The most vexing problem plaguing Rumuomoi's 11kV distribution network is voltage sag and swell, which degrades power quality. There has been no effective mitigation control implemented. purpose of this research to address the issue quality by implementing artificial neural (ANN) with an embedded dynamic restorer (DVR). To begin, trained using input desired data obtained during simulation a prop...
