ABSTRACT:
This project shows the design, control, and exploratory examination of an autonomous wind-solar hybrid energy system feeding 3-stage 4-wire loads. The wind energy block consists of a double-fed induction generator (DFIG) is outfitted with a maximum power point following (MPPT) calculation. The control of DFIG comprises of two converters, to be specific rotor side converter (RSC) and load side converter (LSC) associated consecutive at dc interface.
The MPPT task requires speed control, which is acknowledged utilizing field situated control through RSC. The rotor position required for vector control is evaluated with show reference and energy system calculation. The voltage and recurrence control is acknowledged through LSC. The sun powered photovoltaic (PV) control is extricated utilizing a dc-dc support converter to the basic dc connect. The dc-dc converter is additionally outfitted with MPPT calculation to remove the greatest power from the occurrence irradiance.
The system is displayed in MATLAB and its execution is introduced at conditions, e.g., uneven nonlinear load, changing breeze speeds, and sun oriented light. Under every one of these conditions, streams coursing through stator windings of DFIG are adjusted with low aggregate sounds mutilation (THD). The THDs of load voltages under every single working condition are additionally inside prerequisite of IEEE 519 standard. At last, mimicked results are approved tentatively by building up a model of the framework utilizing a 5-kW sun oriented exhibit test system and a 3.7-kW DFIG.
