Research and application on digital wind power plant technology

Nowadays, the wind power plant industry confront with a serious issue that the wind turbines produced by various manufactures are not compatible with each other because of various communication protocols. This cause difficulties in the operation, maintenance and management for the power plant operators. In order to solve this problem, an IEC 61850 and IEC 61400-25 standard based digital wind power plant solution was proposed based on the experiences got from lots of digital substation projects. Its technical features, system structure and function components were also analyzed. In the light of this solution, several wind power plant projects were implemented. As a result, an up-to-date general integrated digital wind power plant automation system which integrates wind turbine SCADA system, substation SCADA system and wind power plant advanced applications (such as Auto Generation Control-AGC) has been put into services. These new automation systems in the wind power plants worked well and successfully met its original designed targets and requirements, greatly improved the automation level of these wind power plants.
