The Electric Control System And Safety Protection Design Of The Double-fed Wind Turbine

The paper is mainly for the research and design of electric control system and safety protection of the double-fed wind turbine.First of all,the test introduced to us the working principle and operation process of double-fed wind turbine and the electric control system of the general requirements,structure and functions.Surrounding this request and the overall program for each of the electronic control system it carry out a detailed research and give a analysis and design of the basic functions of electronic control system,structure and control strategy respectively.Then give a specific design with the hardware and software of the system.From the system point of view it put forward a theory of units related to electromagnetic interference,analysis,the main sources of interference and specific design to reduce Electro Magnetic interference.Finally,it takes us the security protection levels of wind turbine,research the safety chains and technology of grounding and Lighting-proof System.
