双馈风机控制方式对继电保护动作的影响研究

Research on the Influence of Double-fed Fan Control Mode on Relay Protection Action

将双馈风机接入到配电网中,会对配电网的继电保护动作造成一定的影响,特别是双馈风机的控制方式对继电保护的影响是最为严重的。因此,本文将对双馈风机控制方式对继电保护的影响进行分析。本文首先对双馈风机的概况进行综述,其次对数学模型以及控制策略进行阐述,最后对继电保护的影响进行分析,以供参考与借鉴。

Connecting the doubly-fed fan to the distribution network will have a certain impact on the relay protection action of the distribution network,especially the control mode of the doubly-fed fan has the most serious impact on the relay protection.Therefore,this paper will analyze the influence of the doubly-fed fan control mode on the relay protection.This paper firstly summarizes the general situation of doubly-fed wind turbines,then expounds the mathematical model and control strategy,and finally analyzes the influence of relay protection for reference and reference.
