WEG COMPONENTS AND SALIENT FEATURES: GENERATOR : A highly efficient generator suitable for power conversion operation also ensures that a wide range of speed variations are possible. CONTROLLER : A microprocessor based controller that has a touch screen facility on the operator panel. Hub, Top and Bottom controllers are available. Monitoring the performance of the WEG is done through an in-built SCADA system. POWER CONVERTOR : An IGBT based power convertor with grid fault ride through capability ensures that no separate Capacitor panel is required (during Operation) for power factor improvement, since the power convertor is used to feed power to the grid. SALIENT DESIGN FEATURES OF THE WEG: RRBEL's PS- 1800 kw WEG is designed to endure extreme environmental conditions. The dynamic design of the WEG give a higher level of safety, quality and efficiency. The WEG is suitable for 50 Hz and 60 Hz grid. The WEG is designed for Wind class II and III sites.
