Abstract

Decentralized power plants have to stay connected to the grid during grid disturbances. Only under certain conditions they are allowed to trip. The capability of power generation units (PGU) to withstand a defined voltage-against-time-profile, the so called “low voltage
ride through (LVRT)” capability, has to be proven by type testing or unit testing before they are allowed to be connected to the grid. The most common way to test PGUs is using a test container, which is emulating a fault event in the grid with reduced short circuit power.
Simulations with different setups with and without LVRT test container and variation of the fault location, but always keeping the same short circuit ratio and remaining voltage at the PGU’s connection point, reveal different transient behavior of the device under test. In
this paper the influence of the LVRT test equipment is analyzed in detail and recommendations for
modifications of the test procedure are given.
