IEC 61400-21-2:2023 defines and specifies the quantities that are determined to characterize the electrical characteristics of grid-connected power plants (PPs).
This document defines the measurement and test procedures for quantifying the electrical characteristics as basis for the verification of compliance of PPs. This document defines a uniform functionality test and measurement procedure for the power plant controller (PPC), as a basis for the unit test of the power plant controller.
This document defines the procedures for assessing compliance with electrical connection requirements, including the aggregation methods for power quality aspects such as voltage variations, flicker, harmonics and interharmonics. This document defines the procedures for measurement and fault recording, for example for the verification of power plant electrical simulation models in relation to undervoltage and overvoltage ride-through events.
