    This study proposes a comparative assessment of the leading indicators of power quality measured in a wind farm located in the north of the state of Bahia. The integration of wind farms in the electric power system presents challenges related to the power quality, whose indicators must follow the standards defined as desirable. This fact highlights the importance of monitoring electrical power quality indicators, emphasizing phenomena, parameters, and reference values regarding steady-state voltage, power factor, harmonic distortion, voltage imbalance, voltage fluctuation, short duration, and frequency variation. The power quality indicators were evaluated according to the limits defined in Brazilian standards: Procedimentos de Distribuição de Energia Elétrica no Sistema Elétrico Nacional, established by the Agência Nacional de Energia Elétrica, through normative resolution No. 956/2021; Procedimentos de Rede, prepared by the Operador Nacional do Sistema Elétrico, through normative resolution No. 903/2020. The measurement of electrical quantities was performed using a PowerLogic® energy analyzer, model ION7650, manufactured by Schneider Electric, which is also responsible for measuring the plant's electricity production billing. The analysis of the quality of electric energy is carried out in the generation bus of the enterprise's substat. The recorded values of the measured electrical quantities were satisfactory for presenting a diagnosis capable of evidencing problems related to the power quality.
