提出了一种有利于进行控制设计的STATCOM模型。采用直接反馈线性化、零动态原理,设计了STATCOM无功电流与发电机励磁非线性控制器,该控制可以同时满足发电机励磁与STATCOM装设处电压的稳定性。对单机一无穷大系统进行了数字仿真,结果表明该控制器具有很好的实用效果和优越性。
A STATCOM model which is easy for control design is recommended. By using direct feedback linearization and zero dynamics method, the non-linear controller for the reactive current of STATCOM and generator excitation was designed, which can meet the requirement of stability of generator power angle and that of STATCOM voltage. Numerical simulation of one machine-infinite bus system shows that the controller is effective and advantageous.
