随着交流变频调速技术快速发展,以及新型电力电子器件如绝缘栅双极晶体管(IGBT)、集成门极换向晶闸管(IGCT)等的出现,计算机技术的发展和新型的控制理论的应用,高压变频器也得到了快速发展。在电厂的应用已相当普遍,节能效果及控制水平已被电力系统所认识。文章就西门子高压变频器的原理、特点,以及在火力发电厂中的节能应用进行了分析。
With the rapid development of AC variable frequency speed regulation technology and the emergence of new power electronic devices such as insulated gate bipolar transistors (IGBTs), integrated gate commutated thyristors (IGCTs) and the like, the development of computer technology and the application of new control theory, High-voltage inverter has also been rapid development. The application of power plants has become quite common, and the energy-saving effect and level of control have been recognized by the power system. The article has analyzed the principle, characteristic of Siemens high-pressured frequency changer, and the energy-saving application in the thermal power plant.
