This paper presents a novel STATCOM configuration for voltage quality improvement in wind power generation systems. The proposed STATCOM is formed by cascading two 3-level inverters, bulk inverter' andconditioning inverter', through a coupling transformer.Both inverters are powered by dc-link capacitors and they are charged by a small amount of active power drawn from the grid.Cited by: 5Publish Year: 2009Author: S.

In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply.Images of Switchgear Zero Emission Xi'an Xigao
