Research of Mining STATCOM Based on Hybrid Multilevel H-bridge Inverter
The paper presents a new STATCOM system based on H-bridge inverter. It can be used in mine power network. It has been commonly verified for the positive effects of SVG on the reactive power compensation and voltage fluctuation suppression. This paper focuses on a generalized structure of multilevel power converter where individual voltage sources are not necessarily the same. The cascade H-brid...
متن کاملH-Bridge Multilevel STATCOM for Mining
The quality of the power supply in any industrial environment can have a dramatic effect on the cost of production. This is particularly true in a mining environment, both above ground and underground, because of the remote location of many mining sites. This paper considers various power quality issues and their effects, and then proposes the H-bridge multilevel static compensator (STATCOM) co...
متن کاملResearch on the Multilevel STATCOM based on the H-bridge Cascaded
This paper mainly studies the main circuit topology, the working principle, modulation technique and control strategy of the STATCOM based on H-bridge. The STATCOM direct power control algorithm based on the virtual flux is used to control the AC side reactive power compensation, and in accordance with the principle of conservation of power, the DC side voltage imbalance factors are analyzed, a...
متن کاملDigital Simulation of Multilevel Inverter Based Statcom
This paper deals with simulation of STATCOM used for harmonic reduction with the aid of multilevel VSI circuit. The harmonics in STATCOM due to the voltage ripple are reduced. As a result, the size of inductor and DC capacitor can be reduced. The STATCOM has the great advantage of a fewer number of devices. The VSI is extremely fast in response to reactive power change. The simulation of the ST...
متن کاملMultilevel Inverter Based on Level Switch and H - Bridge
This article proposes a topology for construction of multilevel inverter consisting of H-bridge and level switch. In accordance with the proposed topology Н-bridge inverts voltage and a switch enables to get any number of voltage levels. At that, in comparison with analogues, the above mentioned topology allows saving on expensive power keys. Moreover, a special technique has been developed to ...
