摘要:勵磁裝置是指同步發(fā)電機(jī)的勵磁系統(tǒng)中除勵磁電源以外的對勵磁電流能起控制和調(diào)節(jié)作用的電氣調(diào)控裝置。自50年代以來，隨著時代的進(jìn)展，不論是在控制理論還是在電子器件的研制和實(shí)際應(yīng)用方面，取得長足的進(jìn)展，這些成果進(jìn)一步促進(jìn)了勵磁控制技術(shù)的發(fā)展。 勵磁系統(tǒng)是水電站設(shè)備中不可缺少的部分。在目前在電力電子裝置的研究中，為了克服常規(guī)PID勵磁控制已經(jīng)不能滿足系統(tǒng)運(yùn)行的動態(tài)和靜態(tài)性能，設(shè)計一種新的模糊PID控制，結(jié)合常規(guī)PID控制的優(yōu)點(diǎn)。 關(guān)鍵詞：勵磁系統(tǒng)；自動控制；模糊控制器；MATLAB仿真
ABSTRACT:Excitation device is a synchronous generator excitation system, in addition to the excitation power other than the excitation current from the control and regulation of the electrical control device. Since the 1950s, with the progress of the times, both in the control theory and made ??considerable progress in the development and practical application of electronic devices, these results further promote the development of the excitation control technology. The excitation system is an indispensable part of hydropower equipment. Power electronic devices, in order to overcome the conventional PID excitation control can not meet the dynamic and static performance of the system operation, design a new fuzzy PID control, combined with the advantages of the conventional PID control. Key words: excitation system; automatic control; fuzzy controller; MATLAB simulation |
