  2. The stability of electric power system has been being focused for a long time toprevent a power system from losing synchronism after sudden fault , researchers have done much work and got many accomplishments this paper applied the direct feedback linearization ( dfl ) technique on the power system , a strong nonlinear system simulation results by matlab proved this method efficiency main works and results are as follows : this paper compared some existing methods in excitation control , fast valve control and coordinated control respectively, analyzed the developments and actuality of nonlinear control research in brief, illustrated why ransient stability could be greatly improved by using the fast valve control in chapter 3 , indicated the importance of coordinated control farther this paper introduced the inverse system theory, based on which , discussed the dfl theory, pointed out which had consistency with the inverse theory, expanded the dfl theory combined the idiographic model equations , made which adapt to the model of a single machine - infinite bus power system this paper referenced abundance articles and educed a set of equations , which could describe the dynamical process of excitation and fast valve control for synchronous generators in the equations , there were several very important parameters of power system - - rotor angle ( ) , rotor speed ( ) , generator q axis voltage ( eq ) , transient voltage ( e ' q ) , active power ( pe ) , mechanical input power ( pm ) , valve opening ( ) , generator terminal voltage ( vt ) , based on the model , nonlinear coordinated controller and terminal voltage optimal controller have been designed by using the expanded dfl theory and lq optimal control theory the simulation results showed that the controller could keep power system transiently stable under the effects of a symmetrical 3 - phase short circuit fault , which achieved better postfault regulation compared with another two routine methods , one is the proportion excitation controller and proportion fast valve controller, the other is the proportion excitation controller and the optimal fast valve controller, which could exert good performance when met 1ittle disturbance either

    在介紹逆系統理論的基礎上,詳細介紹了dfl理論,通過較闡明了dfl理論其本質是逆系統方法的一類,並結合具體課題推導出的模型方程將dfl理論進行了擴展,使之適應于電力系統這個強非性對象。通過參考大量的書籍文獻推導出一套實用的可將大型汽輪發電機勵磁與汽綜合起來進行控制的模型方程,此模型方程涵蓋了電力系統中特別人注目的幾個量- -轉子角、轉子轉速、發電機q軸電勢eq 、暫態電勢e ' q 、有功功率pe 、機械功率pm 、汽開度、機端電壓vt ,在此基礎上建立了實用的電力系統簡化的數學模型,並將擴展的dfl理論應用於此模型系統,結合性二次型最優控制理論設計出大型汽輪發電機的非性綜合控制器及機端電壓最優控制器,通過模擬實驗與採用常規的按電壓偏差進行調節的例式勵磁控制器+汽例控制及採用常規的按電壓偏差進行調節的例式勵磁調節器和基於二次型性能指標設計的最優快控汽(考慮發電機的飽和因素)進行了對,證實了採用此種控制器可以有效地提高電力系統的暫態穩定性,並且在電力系統遭受小干擾時同樣具有良好的調節性能。
