- A drastic increase in penetration of renewables into the existing grid network, there is necessity to maintain grid stability,security and reliability. Grid stability is one of the main aspect needs to be monitor in the power system. Power generarting plants should have control capabilities and protection mechanisms inorder to avoid power outages.
- In the past, these requirements are fulfilled by the conventional generating stations. In the recent years a steady rise in the grid integration of renewables so there is a new requirement in the grid codes to maintain the stability of the grid. It has led to the requirement of low voltage ride through (LVRT) capability in wind turbines.
- Grid codes for LVRT capability of wind turbines are proposed in all major wind-energy-producing countries. The testing of LVRT capability compliance of the wind generators as per the specified grid codes during different fault conditions is essential to ensure its reliability.
- The testing process is generally done by the manufacturers and crucial for certification as per the IEC 61400-21 international standard for measurement of power quality characteristics of wind turbines.
