Wind turbines (WTs) are frequently struck by lightning. Electronic devices in the control system of a wind turbine are operating in low voltage levels. Consequently, they are vulnerable to lightning transients. To implement an efficient lightning protection design, numerical simulation is the most economical and efficient method to evaluate the system. However, modeling of such a system is a complex task due to various components and complex configurations. Existing methods are well developed to estimate transients on the scale of the wind farm. However, they are insufficient to evaluate the detailed transient distribution in various cables in the low-voltage side of WT systems. This paper presents a comprehensive modeling procedure to calculate the transients in the control system of the wind turbine. A vector fitting enhanced partial element equivalent circuit method (PEEC) is adopted for the simulation. The influence of various electromagnetic effects on the transient distribution is discussed. A WT with a practical configuration of 14 cables is investigated thoroughly. The influences of various electromagnetic effects on the transient distribution are discussed.
