摘要

摘要。本文研究了风力发电机静电放电效应,这是一种可能的主轴承电流触发源。为了验证静电放电对主轴承电流的影响,建立了一个带有电荷发生器和小型风力涡轮机的实验室装置。在测试中,仅在轴上的- 93 mV驱动电压下发现轴承电流的致命幅度。与共模电压驱动的轴承电流相比,静电放电效应在较低的轴电压和较高的轴承电流幅值下触发轴承击穿。结果表明,静电放电效应是风力发电机组轴承电流的一种模式,对轴承的危害更大。

Electrostatic discharge impacts on the main shaft bearings of wind turbines
Abstract. This paper studies the electrostatic discharge effect in wind turbines, a possible trigger source of the main bearing current. A lab setup with a charge generator and downsized wind turbine was built to verify the impact of electrostatic discharge on the main bearing current. In the test, a fatal amplitude for the bearing current was found at only −93 mV driven voltage on the shaft. Compared with the bearing current driven by the common-mode voltage, the electrostatic discharge effect triggers the bearing breakdown at a lower shaft voltage but much higher bearing current amplitude. The results demonstrate that the electrostatic discharge effect is a pattern of the bearing current in wind turbines and is much more dangerous to the bearing.
