The equipments in the wind farm and monitoring system provided by multiple vendors may not be compatible with each other and make it difficult to do unified maintenance and management. To solve the problem， International Electrotechnical Commission（IEC） has drafted IEC 61400-25 series standard which deals with the communication for the monitoring and control system of wind power plant. In view of the demand of market competition and expansion of wind farm， IEC 61400-25 will finally become a trend in the monitoring and control system of communication. Aimed at popular communication for the monitoring and control system of wind power plant based on object linking and embedding for process control（OPC）， the mapping between IEC 61400-25 and OPC XML-DA is analyzed. A concrete solution for engineering implementation is proposed， and the system structure of communication for monitoring and control system is constructed. The software module structure of OPC service of wind power is designed and the compatibility problem between the communication for monitoring and control system based on OPC and IEC 61400-25 standard is solved.
