| 摘 要： | 针对包含励磁控制的发电机与高压直流输电的交直流互联系统，设计了发电机励磁与高压直流输电的协调控制器。首先建立整个系统的数学模型，然后利用非线性控制理论将系统精确线性化，并结合最优协调控制理论得出协调控制规律。最后应用EMTDC程序进行仿真，结果表明，上述协调控制器能有效地提高整个系统的稳定性。

| Abstract: | The mathematical model of a power system,in which a generator with excitation system is connected to a single-machine infinite bus AC system via high voltage direct current(HVDC) power transmission,is built,and for this power system a controller coordinating the generator excitation with the HVDC power transmission is designed.Using nonlinear control theory,the presented system is accurately linearized and based on optimal coordination control theory the coordination control law for this power system is obtained and is verified by the simulation based on EMTDC.Simulation results show that the proposed controller can improve the stability of the whole system effectively. |
