摘　　要：详细分析了基于能量缓冲统一潮流控制器物理模型中优化消谐ＰＷＭ方法开关脉冲的产生机理，提出了一种基于工控机和单片机来用公用ＲＡＭ技术传递数据的控制系统，解决了电网频率跟踪，相差调控等技术难题，为其物理模型的研制奠定了基础．The paper discusses and analyses the on-off pulse generation in prototype of Unified Power Flow Controller (UPFC) with .energy snubber in which selective harmonic elimination (SHE) PWM method is used in details. A kind of control system is proposed, which is based on data moving between industrial control computer and single-chip computer by using common RAM. The problems on the electric-network frequency track and phases regulation are solved and a foundation for the manufacture of UPFC prototype is laid.
