摘要
采用超导储能装置(Superconducting magnetic energy storage,SMES)的二阶模型,得到含SMES的单机无穷大电力系统模型。进而利用Lagrange化和间接Hamilton化理论,构造了该动态系统的Hamilton函数,并提出相应的SMES的稳定控制策略。最后,利用Matlab进行仿真验证了笔者所提出控制律的正确性和有效性。结果表明,在大干扰的情况下,基于间接Hamilton化理论所设计的超导储能控制器能使系统快速地恢复到稳定运行状态,提高电力系统的暂态稳定性。
Considering the second order model of super conducting magnetic energy storage （SMES）, this paper builds up a model of the single-machine infinite-bus system （SMIB） with SMES. Then based on the Lagrange theory and indirect Hamilton theory, the Hamiltonian energy function is constructed and corresponding control strategy is proposed. Finally, the correctness and efficiency of the controller is verified using the MATLAB software package. Simulation results manifest, under the large disturbances, that proposed control strategy can quickly make the system back to the stable operation state and imorove the transient stability of the oower s,cstem.
