IEC 61400-27-2:20 20规定了风力涡轮机和风力发电厂电气仿真模型的验证程序，旨在用于电力系统和电网稳定性分析。验证程序基于IEC 61400-21（所有部件）中规定的试验。验证程序适用于中规定的通用模型 IEC 61400-27-1和其他基频风力发电厂模型和风力涡轮机模型。 风力涡轮机模型的验证程序侧重于故障穿越能力和控制性能。故障穿越能力包括对平衡和不平衡电压骤降以及电压骤降的响应。控制性能包括有功功率控制、频率控制、合成惯量控制和无功功率控制。风力涡轮机模型的验证程序参考IEC 61400-21-1中规定的试验。风力涡轮机模型的验证程序参考风力涡轮机终端。

IEC 61400-27-2:2020 specifies procedures for validation of electrical simulation models for wind turbines and wind power plants, intended to be used in power system and grid stability analyses. The validation procedures are based on the tests specified in IEC 61400-21 (all parts). The validation procedures are applicable to the generic models specified in
IEC 61400-27-1 and to other fundamental frequency wind power plant models and wind turbine models.
The validation procedures for wind turbine models focus on fault ride through capability and control performance. The fault ride through capability includes response to balanced and unbalanced voltage dips as well as voltage swells. The control performance includes active power control, frequency control, synthetic inertia control and reactive power control. The validation procedures for wind turbine models refer to the tests specified in IEC 61400-21-1. The validation procedures for wind turbine models refer to the wind turbine terminals.
