This part of IEC 61850 is intended to provide explanations on how to use the Logical Nodes defined in IEC 61850‑7‑410 as well as other documents in the IEC 61850 series to model complex control functions in power plants, including variable speed pumped storage power plants.

IEC 61850‑7‑410 introduced the general modelling concepts of IEC 61850 to hydroelectric power plants. It is however not obvious from the standard how the modelling concepts can be implemented in actual power plants.
