统一潮流控制器的瞬时矢量控制算法

统一潮流控制器由于其功能的全面，控制过程中待处理变量多、计算工作量大，因而对控制器的运算能力和工作速度有很高的要求。针对这个问题，中提出了瞬时矢量的概念，并介绍了一种新的快捷有效的检测控制算法－－瞬时矢量控制算法。通过这种方法，可以由采样输入的系统变量瞬时值，直接求得控制输出参量的瞬时值，极大地提高系统的工作速度和效率。章还介绍了统一潮流控制器的基本结构和功能及实现各种基本功能时有关变量间所对

INSTANTANEOUS VECTOR CONTROL ALGORITHM OF THE UPFC

Due to the manifold function of UPFC, there are many variables and heavy operation in its working process, so that the strong calculation capacity and high operating speed are essential to UPFC. For this reason, a concept of instantaneous vector is put forward, and from this, a new instantaneous vector control algorithm is presented in this paper. With this algorithm, the instantaneous value controlling the output parameters can be immediately derived from the input sampled instantaneous value of the system variables, so that this algorithm is very convenient and effective. This method can be also applied to other control fields of electric power system, in which the angle and amplitude needs to be dealt with. In this paper the structure and function of UPFC is presented, the vector relation between interrelated variables and corresponding instantaneous vector equation are put forward.
