N2 - In order to lay the research foundation for the protection relay in the wind power integration, this paper analyzes general fault characteristics of wind power system based on the controlled characteristics of wind turbine generators and the features of power electronic devices. The fault characteristics of wind power system are determined by the source and the network topology. The influence factors of wind power source are first analyzed based on the structure of wind turbine generator. Then, depending on the control theory of wind power, the general fault characteristics of wind power source are studied with the test data of a single wind turbine generator in the low-voltage ride through (LVRT) process. Finally the general fault characteristics are verified by wind power system simulation and field fault record data. The research results reveal that under the control effect and the limit of power electronics, the wind power source has the fault characteristics of weak feedback, high harmonics, frequency deviated, and unstable source impedance.
