一种用于风力发电机组的零序电压检测模块设计

Design of Zero Sequence Voltage Detection Module for Wind Turbine

随着科技的发展,风力发电机组的保护功能越来越完善。通常风电机组不配备零序电压保护功能,为了应对某些工况下风电机组的不安全状况,个别类型的机组需增加零序电压检测及保护的能力。本文介绍一种适用于风电行业的零序电压检测模块的具体设计方案。主要阐述整个模块的工作原理,并记录具体的实验数据。

With the development of science and technology,the protection function of wind turbine is becoming more and more perfect.Generally,wind turbines are not equipped with zero sequence voltage protection function.In order to deal with the unsafe conditions of wind turbines under some working conditions,individual types of units need to add zero sequence voltage detection and protection functions.This paper introduces a specific design scheme of zero sequence voltage detection module suitable for wind power industry.This paper mainly expounds the working prin-ciple of the whole module,and records the specific experimental data.
