Abstract

The increase in addition of new wind generation to the grid have several issues related to grid stability and security. The LVRT capability of wind turbine is one of the major concerns during the grid fault and many countries tail different LVRT requirements of grid codes to ensure the proper operation of wind turbine throughout the fault condition without tripping it from the grid. Consequently, the high penetration of DER to the grid requires an optional method for controlling active and reactive power injection during the normal operation condition and grid fault. This paper discusses about two significant technical solution for LVRT during grid connected mode and seamless transfer during islanding and stabilisation after islanding. The objective of this paper is to comprehend these challenges in implementation of LVRT capability in India in order to come up with appropriate solutions. Simulation results on a 2.3-MW EESG-based WECS using DIgSILENT/Power Factory environment demonstrate the effectiveness of the proposed LVRT scheme under both balanced and unbalanced grid voltage sags.

一种提高电液发电机组暂态稳定性的控制策略

新增风力发电并网带来了几个与电网稳定性和安全性相关的问题。风电机组的LVRT能力是电网故障时人们关注的主要问题之一，许多国家对电网规范的LVRT提出了不同的要求，以确保风电机组在整个故障状态下正常运行而不脱网。因此，DER对电网的高渗透要求在正常运行状态和电网故障时，有一种控制有功和无功功率的可选方法。本文讨论了LVRT并网模式下的两种重要技术解决方案，以及孤岛期间的无缝输送和孤岛后的稳定。本文的目的是了解在印度实施LVRT能力的这些挑战，以便提出适当的解决方案。基于DIgSILENT/Power Factory环境的2.3 mw eesg WECS仿真结果表明，所提出的LVRT方案在平衡和不平衡电网电压跌落下都是有效的。
