|
摘要
通过建立移动电站同步发电机非线性数学模型,研究了基于STF算法的交流跟踪励磁控制策略,其可以有效抑制系统扰动并实现系统状态在线估计。对发电机模型参数进行了仔细观测,对交流跟踪励磁控制策略进行了理论分析,对试验结果与传统励磁控制数据进行了对比。仿真实验结果验证了基于STF算法的交流跟踪励磁控制策略的优越性。
Through the establishment of the nonlinear mathematical model for the synchronous generators of the mobile power station,the AC tracking excitation control strategies based on STF algorithm are presented,which can effectively suppress the disturbance of the system and can realize the on-line estimation for the system status.By the observation of the generator model parameters,the theoretical analysis of the AC tracking excitation control strategies,the experimental simulations and the comparisons with the traditional excitation control strategies,the superiority of the AC tracking excitation control strategy based on the STF algorithm is verified.
