This standard specifies the unit test method and the whole station simulation verification method for the high voltage ride-through capability of photovoltaic power stations. It is applicable to newly built, remodeled or expanded photovoltaic power stations. The referenced documents include the technical requirements of the transformer, the guidelines for modeling photovoltaic power generation systems, and the testing procedures for the models and parameters of photovoltaic power generation systems. The terms and definitions include high voltage ride-through, voltage rise generating devices, etc. The test objects cover all types of photovoltaic power generation units. The test should be carried out when the photovoltaic power generation unit is in normal operation. The photovoltaic power station model should be established based on the test data of the photovoltaic power generation unit, and
