Abstract :

<p>&lt;p&gt;&amp;nbsp;&lt;b&gt;&lt;span style=&quot;font-size: 10pt; line-height: 115%; font-family: &amp;quot;Times New Roman&amp;quot;, serif;&quot;&gt;The use of wound rotor induction machine has become very popular in wind power generation since last many years. The WRIM can generate power at variable speed and are operated with converters whose rating is only fraction&amp;nbsp; of wind turbine rating. The main drawback of WRIM&amp;nbsp; based wind turbine is that it is very sensitive during&amp;nbsp; grid disturbance particularly for the voltage sags. As the WRIMs are widely used in wind power generation, the transient response of the WRIM&amp;nbsp; during grid disturbance has been investigated extensively in recent year. The main focus of this paper is to analyse the transient response of WRIM under balanced voltage sag from the theoretically. The result of this analysis helps to understand the problem of existing system and provides very useful tools to solve the existing problem and to improve new propose control as well as strategies.&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;</p>
