In this paper, a new 11-level topology of symmetrical Multilevel Inverters (MLIs) is proposed. The proposed topology offers reduced number of components as compared with conventional and recently published topologies. The Selective Harmonic Elimination (SHE) is adapted for switching modulation that removes undesired harmonics. A comparative analysis of proposed topology with other proposed topologies...
This paper deals with a decoupled electronic load controller (DELC) for an isolated asynchronous generator (IAG), used in constant power pico hydro power generation for feeding three-phase four-wire loads. The proposed DELC is used to control the voltage and frequency in the decoupled manner. The proposed decoupled electronic load controller is combination of a voltage regulator (VR) for regulating...
The dynamic voltage restorer (DVR) is used to regulate the voltage at the load terminals from various power quality problems like sag, swell, harmonics, unbalance etc., in supply voltage. In this paper, a novel control strategy is proposed to control a capacitor supported DVR for sag, swell, harmonics and unbalance in supply voltage. The reference signal for the series connected DVR is obtained indirectly...
This paper presents the control of battery energy storage system (BESS) with diesel generator (DG) set. The performance of the DG set is observed best when operated at full load or near full load (up to 80-100% load) condition. For this purpose a BESS is employed which ensures the load on the generator remains in between 80% to 100% of full load. Under light load condition (load less than 80%) the...
