风力发电模型在MATLAB中的模型建立

风机仿真模型及代码 Simulation of a Microturbine Generation System for Grid Connected and Islanding Operations The ever-increasing need for electric power generation, steady progress in the power deregulation and utility restructuring, and tight constraints over the construction of new transmission lines for long distance power transmission have created increased interest in distributed generation (DG) sources[1~3]. The fundamental concepts for the penetration of DG technologies are the high efficiency of the energy conversion process and the limited emission of pollutants with respect to conventional power plants. They are relatively small in size (relative to the power capacity of the system to which they are connected), and are modular in structure. These power generation devices can be placed in power systems (mainly at the distribution level) for grid reinforcement, offering a higher flexibility and load management, reducing power losses and on-peak operating costs, improving voltage profiles and load factors, deferring or eliminating the need for system upgrades, and improving system integrity, reliability and efficiency.
