Speed Control of Brushless Doubly-fed Reluctance Generator under MTPIA and UPPF Conditions for Wind Power Application

Two specific conditions, such as maximum torque per inverter ampere (MTPIA) and unity primary power factor (UPPF) are considered in the present work for a comparative performance analysis while speed control of brushless doubly-fed reluctance generator (BDFRG) using primary field-oriented control (PFOC). The study is based on the active power, reactive power, and power factor of both the stator windings of BDFRG in super-synchronous, synchronous, and sub-synchronous speed zones. The study also deals with the assessment of the minimum rating of the inverter required in both the conditions for successful operations. The relevant studies are done in MATLAB/Simulink. The prima facie objective of the present work is to affirm the candidature of BDFRG in wind power generation.
