摘要
针对含有先进静止无功发生器(ASVG)的单机无穷大系统,建立了4阶非线性状态空间数学模型.基于Hamilton能量函数理论,设计了ASVG安装点电压与发电机励磁的新型非线性协调控制器.数字仿真结果表明,在系统遭受到较大干扰的情况下,所设计的控制器可同时满足发电机励磁与ASVG装设处电压的暂态稳定性要求.
The four order nonlinear unified state-space system model is established for a single-machine infinite-bus power system with advanced static var generator (ASVG). Based on Hamiltonian energy theory, the new non-linear coordinated controller is designed between the bus-voltage of system, where ASVG is installed, and synchronous machine excitation. Simulation results of the single-machine infinite-bus power system with ASVG show that the proposed controller can meet the requirement of transient stability of synchronous machine power angle and terminal voltage of ASVG for the studied power system with ASVG when subjected to the larger disturbance.
