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。
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.
