【 摘 要 】

Wind power plants include wind power generation systems, which contain machinery, electrical appliances and their control equipment. Each equipment requires a corresponding cable to connect. In the current application of power cables, the cables used are three single-core conductors or one three-core conductor. Moreover, the wind energy cable must be able to rotate in the forward and reverse directions with the wind turbine. Therefore, the cable must have a soft structure, sufficient tensile strength and bending resistance, and oil and low temperature resistance for the insulating sheath. Due to the harsh environment of wind power generation, the fan has a long service life, and the cable rotates with the fan, which requires high performance of the cable. At this time, the insulation detection of the cable is particularly important. For the current power cable oscillation wave test system, most of the literature only introduces the simple principle of the detection system, and studies based on single-core cable. Based on the three-core cable, this paper performs oscillating wave detection on the three-core cable, and designs the simulation system and studies the influence of insulation defects in different parts. From the experiment results, the proposed system is able to successfully simulate the working procedure of the oscillation wave test system, and to collect the effective partial discharge signals, which validates the effectiveness of the simulation system.
