<p>风机仿实模型及代码 Simulation of a Microturbine Generation System for Grid Connected and Islanding Operations The eZZZer-increasing need for electric power generation, steady progress in the power deregulation and utility restructuring, and tight constraints oZZZer the construction of new transmission lines for long distance power transmission haZZZe 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 conZZZersion process and the limited emission of pollutants with respect to conZZZentional power plants. They are relatiZZZely small in size (relatiZZZe to the power capacity of the system to which they are connected), and are modular in structure. These power generation deZZZices can be placed in power systems (mainly at the distribution leZZZel) for grid reinforcement, offering a higher fleVibility and load management, reducing power losses and on-peak operating costs, improZZZing ZZZoltage profiles and load factors, deferring or eliminating the need for system upgrades, and improZZZing system integrity, reliability and efficiency.</p>
