IEC 61400-25-5:20 17规定了测试实施合规性的标准技术，以及声明性能参数时应用的特定测量技术。这些技术的使用将增强用户购买易于集成、正确操作并按预期支持应用程序的系统的能力。IEC 61400-25的这一部分定义了:风力发电厂使用的服务器和客户端设备符合性测试的方法和抽象测试用例；根据IEC 61400-25（所有部分）中规定的通信要求，在所述设备中测量的指标。与上一版相比，此新版本包括以下重大技术变更: -与IEC 61850-10:20 12中的结构和测试用例相协调； -通过增加对IEC 61850标准系列的引用，减少标准之间的重叠和简化。

IEC 61400-25-5:2017 specifies standard techniques for testing of compliance of implementations, as well as specific measurement techniques to be applied when declaring performance parameters. The use of these techniques will enhance the ability of users to purchase systems that integrate easily, operate correctly, and support the applications as intended. This part of IEC 61400-25 defines: the methods and abstract test cases for compliance testing of server and client devices used in wind power plants; the metrics to be measured in said devices according to the communication requirements specified in IEC 61400-25 (all parts). This new edition includes the following significant technical changes with respect to the previous edition:
- harmonization with structure and test cases in IEC 61850-10:2012;
- reduction of overlap between standards and simplification by increased referencing to the IEC 61850 standard series.
