| 摘 要： | 为了消除LOEC存在稳态误差的现象，从电力系统的运行实际出发，推导了对发电机机端 电压偏移量施加积分控制时系统的线性化增广状态方程式，并在此基础上推导了积分型线性 最优励磁控制规律(ILOEC)。仿真结果表明：在提高系统稳定极限和改善系统动态特性方 面，ILOEC与LOEC具有相同的能力。同时ILOEC能消除发电机机端电压的稳态误差，提高了控 制精度，改善了系统运行水平。

| Abstract: | In view of the steady-state errors of LOEC and considering the power system operation condition.we develop the power system linear extended state equations in applying integral control to generator terminal voltage deviation.on this basis the integral linear optimal excitation control(ILOEC)is obtained.The results of computer simulation show that the ILOEC has the same ability as LOEC in enhancing power system stability and improving power system dynamic quality. meanwhile by using ILOEC the generator voltage steady-state errors arc eliminated and the control precision is increased. |
