Abstract: As the new energy sources such as wind power, photovoltaic power generation are in forming a new wave of global electricity market, more and more Chinese contractors are taking part in the global scope of wind farm construction project. Comparing with the power market of China, due to different national management system in power grid, design practices, standards of execution in the construction of wind power projects, many Chinese contractors are not acclimatized in the design interface management. Based on the domestic wind power project in different stages of the design task and subsequent equipment procurement for wind power plant, construction drawing design, equipment debugging and with a reference of the project execution experience in Vietnam wind power market at the same time, an analysis is conducted to clarify the internal logical relations of these process and how to restrain each other, and what appropriate response measures should be taken, It provides reference experience and suggestions for the design interface management in the subsequent wind farm project construction.
