Research on AC tracking optimal control technique applied in mobile power station

为解决目前移动电站所用控制技术使电站存在输出电压稳定度差、负载变化时调节时间长的问题,提出了电站的交流跟踪最优控制技术模型,从理论分析和建模仿真两方面研究了该技术应用的可行性及优越性,并与传统励磁控制技术对电站输出电能质量的影响进行了比较。仿真结果表明:交流跟踪最优控制技术可以在电站控制中获得应用,相较于传统励磁控制技术,前者能够明显提高输出电压稳定度,改善输出电能质量。

In order to resolve the problems of poor stability of output voltage and long adjusting time existing in the mobile power station aroused from the current control technique while loads changing, a model about AC tracking technique was proposed. The feasibility and superiority of the technique were researched from two sides： theoretical analysis and modeling simulation. The results show that： the AC tracking control technique can be used in the mobile power station, with which the stability of output voltage is improved and the output power quality is more perfect.
