【摘要】 针对单机无穷大系统,建立了包含先进无功发生器(ASVG)的三阶状态空间模型。采用广义Ham ilton能量函数理论,考虑电力系统的非线性特性,设计了ASVG安装点电压与同步发电机励磁非线性控制器,该控制可以同时满足同步发电机励磁控制的功角稳定性与ASVG装设处电压的稳定性。单机-无穷大系统数字仿真结果验证了该控制律的有效性。更多还原

【Abstract】 The three order unified state-space system model is established for a single-machine infinite-bus power system with ASVG(advanced static var generation).The non-linear coordinated controller based on generalized Hamiltonian energy theory for the bus-voltage of system,where ASVG is installed,and synchronous machine excitation was designed and the non-linear property of the dynamic system is well preserved and utilized,which can meet the requirement of stability of generator power angle and that of ASVG voltage.Simulation results of the single-machine infinite-bus power system with ASVG verify the effectiveness of the controller.更多还原
