摘要
为了进行大型电力变压器强油风冷系统的试验,验证改进的控制系统的有效性,本文通过建立风冷系统的基本结构和各环节的数学模型,组成系统动态结构图,在Matlab/Simulink下进行仿真试验来观察系统的输出响应。通过观察强油风冷系统的输出特性,为了提高系统的稳定性,加入合适的控制器,在Matlab/Simulink的仿真集成环境中直接设置并修改PID参数,使强油风冷系统得到满意的输出响应。仿真结果为实际应用提供了理论依据。
In order to test and validate the improved control system,this paper presents a simula- tion of the dynamic structure of the forced--oil cooling system of large power transformers under Mat- lab/Simulink through establishing the basic structure and mathematical models of the various aspects of the cooling system to observe the system＇s output responses. Based on the output responses ob- served of the forced--oil cooling system, a suitable controller is added into the system to improve the stability of the system and by setting and modifying the PID parameters directly in the integrated envi- ronment of Matlab/Simulink simulation satisfied output responses are obtained. The simulation results provide a theoretical basis for practical applications.
