中文摘要：

大型风电场中的风电机组和监控系统一般由多个厂商提供，相互兼容困难，难以进行统一维护与管理。遵循IEC61400—25标准的信息模型、信息交换模型及对Web Services的映射方法，设计了基于Web Services的风电场监控软件集成服务模型，讨论了基于该模型的多个异构风电机组与服务端互联互通的问题，给出了风电机组标准服务接口的定义方法和安全通信机制。通过对该模型的工程实现与应用分析，论证了所做工作对风电机组的统一监控和集成管理等问题的解决具有观．实意义与应用价值。

英文摘要：

In the large-scale wind farm, wind turbines and monitoring control systems involved in more than one supplier end up with a number of incompatible systems. This causes operational didficulties and makes it hard to maintain and manage, Some aspect of IEC 61400-25 standard is followed in this paper, such as the information model, the information exchange model, and the method for mapping to Web services. A Web services based integrated service model for the wind farm monitoring is designed. The communication problems between heterogeneous wind turbines and servers are discussed in the model. Then the methods about how to define wind farm Web services interface and security communication are given out. Through engineering implementation and model analysis, it is demonstrated that the work in this paper could provide reference and experience to resolve some problems, such as unified monitoring of heterogeneous wind turbines and integration management.
