脉冲负载下有限容量系统运行特性的仿真研究

脉冲负载是一种功率波动明显、频率切换频繁的负载，而有限容量系统的系统惯性很小，非常容易受到负荷波动的影响，含有脉冲负载的有限容量系统动态过程复杂。为了研究脉冲负载对有限容量系统运行特性的影响，根据脉冲负载的特性建立了基于MATLAB/Simulink仿真模型，定义了脉冲负载下有限容量系统电气特性的计算公式，分析了脉冲负载在不同工作模式时对有限容量系统运行特性的影响规律。结果表明该模型可以较真实的反应脉冲负载的特性，且不同的负载参数对有限容量系统运行特性的影响规律也不相同。

Simulation study on operating characteristics of pulse load on the limited capacity system

The limited capacity of the system inertia is pretty small, and it is highly susceptible to load fluctuations. Represented by digital radar is a kind of pulse load which power switches fast and in large range. It is pretty obvious with the frequency fluctuation and voltage fluctuation when the limited capacity of the system work with pulse load,and the dynamic process is complicated. In order to study the working characteristic effect on the limited capacity system of the pulse load .This paper built the simulation model about the limited capacity of the system with pulse load based on MATLAB/Simulink and defined the pulse under load calculation formula of electric characteristic of the limited capacity of the system and studied the effect law of pulse load on the limited capacity system. The results show that the model can be a real response characteristics of the pulse load and the effect law on the limited capacity system is different with the different load parameters.
