有限容量系统脉冲性负荷建模与仿真

Modeling and simulation of pulsed power load inlimited capacity system

随着电力电子技术的发展,特殊负荷对电力系统,尤其是有限容量电力系统的电能质量影响已表现得尤为突出。提出了脉冲性负荷的定义,在分析脉冲负载机理的基础上,设计了3种脉冲负载电路结构模型。最后将这几种脉冲负载模型接入有限容量系统进行仿真分析,提出了这3种负载模型对发电机的影响和各自的适用场合。

With the rapid development of power electronic technology, a distinct effect of special loads on power quality of power system, especially on limited capacity system, is presented. A definition for the pulsed power load is ad- vanced, and three types of circuit structure model of pulsed power load are devised. With the analysis of its fundamen- tal, the differences of modeling are compared and simulated. Finally, these models are separately jointed to a limited capacity system to simulate and analyze the effect upon power system.
