Abstract |
|
This paper presents an approach of implementing Inverter-Less STATCOM by AC chopper in which AC chopper is placed between the AC line and compensating capacitor for desired VAR control. For this we place C-buck and C-boost cell configurations instead of inverter. Dynamic VAR support is necessary to grid for balancing the faults on the system. The conventional sources of VARs which are capacitor bank and generator are too slow to provide desired impact. STATCOMs have fast response for dynamic control but they are much costly as they consist of large DC/AC inverters and significant high levels of energy storage. Inverter-Less STATCOM provide dynamic control of VAR and there is no need of storage energy. The principle of operation, design and methods of the IL-STATCOM has been discussed in detail with simulation and experimental results to validate the same. |
