After the characteristics and development of excitation system of synchronous generators are analyzed , micro - computer regulating theory of excitation system is discussed , this dissertation presents a scheme of designing excitation system with programmable computer controller ( pcc ) and igbt , and pcc igbt excitation system of turbine generator is also developed according to the above mentioned 本文在全面分析同步发电机微机励磁装置特点及发展现状的基础上,论述了微机励磁调节的原理,提出基于可编程计算机控制器( pcc )控制的绝缘栅双极晶体管( igbt )励磁系统的设计方法,并在此基础上开发了基于pcc控制的水轮发电机igbt励磁系统。
With the larger and larger scale of power system , the problem that the traditional control theories of excitation controllers of turbine generator are not competent as before appears , however , the developing intelligent control ( ic ) theory and updated optimization theory supplies some solutions to this problem . at the beginning of this dissertation , the actuality and trend of the control scheme of excitation control system of turbine generator and soft - compute theory are stated 水轮发电机励磁控制器是电力系统中十分重要的控制设备,对保证电能质量起到至关重要的作用。日益复杂的电力系统使得传统的励磁控制方式已不能满足其控制要求,而蓬勃发展的智能控制理论和新型优化算法为解决这一问题提供了出路。
