Large-scale integration in transmission networks has led to several challenges; one of which is the need for increased transmission capacity to transport a bulk amount of power without affecting the voltage. In case of transmitting power to large distances series compensation is used along with Doubly-Fed Induction Generator (DFIG) wind turbine and it is simulated using MATLAB Simulink and the results obtained are validated. DFIG wind turbine is operated at normal operating state. Due to series compensation Sub Synchronous Resonance (SSR) occurs which is quite harmful to the wind generator because of the frequency variation, the gear mechanics of the generator gets damaged. When a larger disturbance occurred in any part of the study system at any bus bar, the effect of SSR would be more harmful. The effect of SSR depends on the compensation percentage we used for series compensation. SSR can be mitigated by using Flexible AC transmission System (FACTS) devices such as STATCOM, SVC, and SSSC. We use STATCOM because of its high stability margin, low switching loss and variable voltage rating. Whenever disturbance occurs in the transmission line then STATCOM comes into action by supplying reactive power and absorbing real power thus maintaining the system stability. The STATCOM controller gives pulse to the STATCOM for respective action such as real power absorption or reactive power injection. Thus the Wind turbine is protected and system stability is maintained.

传输网络的大规模集成带来了一些挑战。其中之一是需要增加传输容量以传输大量功率而不影响电压。在将功率传输到大距离的情况下，将串联补偿与双馈感应发电机（DFIG）风力涡轮机一起使用，并使用MATLAB Simulink对其进行仿真，并验证所获得的结果。DFIG风力涡轮机在正常运行状态下运行。由于发生了串联补偿，因此会发生次同步谐振（SSR），由于频率变化，这对风力发电机非常有害，发电机的齿轮机构会受到损坏。当研究系统的任何部分的任何母线都发生较大的干扰时，SSR的影响将更加有害。SSR的效果取决于我们用于串联补偿的补偿百分比。通过使用诸如STATCOM，SVC和SSSC之类的灵活AC传输系统（FACTS）设备可以减轻SSR。我们使用STATCOM是因为它具有较高的稳定性裕度，较低的开关损耗和可变的额定电压。每当传输线发生干扰时，STATCOM就会通过提供无功功率和吸收有功功率而起作用，从而保持系统的稳定性。STATCOM控制器向STATCOM发出脉冲，以执行相应的动作，例如有功功率吸收或无功功率注入。因此，风力涡轮机受到保护，并保持了系统稳定性。我们使用STATCOM是因为它具有较高的稳定性裕度，较低的开关损耗和可变的额定电压。每当传输线发生干扰时，STATCOM就会通过提供无功功率和吸收有功功率而起作用，从而保持系统的稳定性。STATCOM控制器向STATCOM发出脉冲，以执行相应的动作，例如有功功率吸收或无功功率注入。因此，风力涡轮机受到保护，并保持了系统稳定性。我们使用STATCOM是因为它具有较高的稳定性裕度，较低的开关损耗和可变的额定电压。每当传输线发生干扰时，STATCOM就会通过提供无功功率和吸收有功功率而起作用，从而保持系统的稳定性。STATCOM控制器向STATCOM发出脉冲，以执行相应的动作，例如有功功率吸收或无功功率注入。因此，风力涡轮机受到保护，并保持了系统稳定性。
