柴油发电机组建模及其带脉冲负载系统运行分析

脉冲负载逐渐成为电力负载的发展趋势,与传统负载不同,这类持续加卸载的突变型负载对于柴油发电机组等容量和惯性较小的冲击较大,易造成系统运行不稳定。分析柴油发电机组带雷达脉冲负载的系统结构,结合脉冲负载的工作特点对柴油发电机组结构进行细化考虑,建立柴油发电机组的数学模型。并在Matlab/ Simulink中搭建系统仿真模型,分析了脉冲负载工作时系统的运行情况,研究了系统的运行与脉冲负载功率PL、输出占空比D、和开关周期TS的关系。搭建了柴油发电机组带脉冲负载系统的试验平台,通过试验验证了所建模型能够较真实地反映系统的运行行为。

Diesel Generator Set Modeling and Analysis of Operation with Pulsed Load System

The pulse load gradually becomes the development trend of the electric load. Different from the traditional load, this type of continuously loaded and unloaded catastrophic load has a greater impact on the capacity and inertia of the diesel generator set, which may cause unstable system operation. Analyze the system structure of the diesel generator set with radar pulse load, combine the working characteristics of the pulse load to consider the diesel generator set structure and establish the mathematical model of the diesel generator set. The system simulation model is built in Matlab/ Simulink. The operation of the system under pulse load is analyzed. The relationship between system operation and pulse load power PL, output duty cycle D, and switching period TS is studied. Finally, a test platform for a diesel generator set with a pulsed load system is set up. It is verified through experiments that the model can reflect the operating behavior of the system more realistically.
