【摘要】 本文基于动模试验,对影响电力系统电压稳定性的一种特殊负荷——空调负荷进行了细致的研究,并分析了空调负荷的电压、频率静特性,启动特性,停机特性以及在不同条件下的电压扰动特性,在此基础上建立了空调负荷模型。本文还详细介绍了一种用于研究电力系统电压稳定性的试验中的变压器有载调压装置的开发和应用过程,试验证明本装置能够很好的模拟系统中实际使用的OLTC装置的各项功能。试验结果达到了对数字仿真验证的目的。更多还原

【Abstract】 The air-conditioner, which is one kind of special load effecting the power system stability to a great extent ,is researched carefully in the thesis based on the laboratory test. Its load characteristics are analyzed,including the static characteristics with respect to the voltage and frequency variations .starting characteristics,drop off characteristics,as well as its responses to voltage dips under various conditions. The air-conditioner load model is also built in this thesis. The development and application of a control system for on-load tap changing transformers, which is used in the experiment for researching the power system stability,is introduced in the paper .The experiment results prove that the developed device can simulate all functions of OLTC in application.The experiments conform to the results from digital simulation.更多还原
