    Abstract: Introduction was made to the characteristic and its damages of overvoltage in wind farms. This paper established a wind farm model of PSCAD electromagnetic transient simulation, analyzed the process of closing overvoltage, and proposed overvoltage protection measures of wind turbines transformers using resistance-capacitance absorber. The results show that adopting suitable resistance-capacitance protector could restrict the amplitude of voltage and gradient within the reasonable scope, which prevents wind farms closing overvoltage effectively.
    Key words: wind farm; overvoltage; RC device; insulation; cable system
