本文介绍了一个集中控制的设计方案，在一个实时的基于实验室的动态模拟器的实施。一个集中的多变量控制算法的设计采用远程反馈信号考虑延迟信号传输。所传输的信号可以用于使用单个控制器的多摆动模式阻尼。这样的算法是数值密集型的，由于高控制器的大小和预测器，照顾信号传输中的延迟。所提出的控制器的性能证明了通过实际实施使用安装在PC-ATX的快速原型控制器。实验测试的结果示出了使用基于PC的多处理器技术的Linux的电力系统的详细模型。
The paper describes the implementation of a centralised control-design scheme in a real-time laboratory-based dynamic simulator. A centralised multivariable-control algorithm is designed employing remote feedback signals considering delay in signal transmission. The transmitted signals can be used for multiple-swing-mode damping using a single controller. Such an algorithm is numerically intensive owing to the high controller size and the predictor that takes care of the delay in signal transmission. The performance of the proposed controller is demonstrated by practical implementation using a rapid-prototyping controller mounted on a PC-ATX. Results of the experimental tests are shown for a detailed model of the power system implemented using Linux PC-based multiprocessor technology.
