What is LRS and GRR

Question

What is LRS and GRR

Accepted Answer

LRS stands for Load Rejection Switching and GRR stands for Grid Rejection Switching.

LRS is a technique used to test the ability of a generator to withstand sudden load rejection.
GRR is a technique used to test the ability of a generator to withstand sudden grid rejection.
Both LRS and GRR are important tests for ensuring the reliability and stability of power systems.
During LRS and GRR tests, the generator is disconnected from the load or grid, respectively, and the response of the system is observed.
If the generator can maintain stability and voltage regulation during these tests, it is considered to be reliable and suitable for use in the power system.
