论文摘要
在本文中，测量了电压下降并分析其动力学的电源载荷的功率响应。基于此，得出了可用于电压稳定性研究的动态模拟模型。为此，考虑了四个具有不同功率因数技术的负载。另外，在实验室中测量了电网阻抗和输入过滤器对功率响应的影响。根据测量结果，描述了仿真模型。还概述了如果没有可用的详细信息，则负载的组成部分通常会尺寸。与测量值的比较表明，模拟模型捕获了主要动力学。在论文的末尾，将负载模型与短期电压稳定性用例中的恒定功率负载进行了比较。结果表明，在电压下降的情况下，功率电子负载对短期电压稳定性具有更大的积极影响。总体而言，本文的贡献是鉴定了用于不同电压滴剂的电力电子负载的基本功率动力学，以及随后推导合适的模拟负载模型以进行电压稳定性研究。
In this paper, the power response of power electronic loads in case of voltage drops are measured and their dynamics are analysed. Based on this, dynamic simulation models are derived which can be used for voltage stability investigations. For this, four loads with different power factor techniques are considered. In addition, the impact of the grid impedance and input filter on the power response are measured in the laboratory. Based on the measurements, the simulation models are described. It is also outlined under which aspects the components of the loads are normally dimensioned if no detailed information is available. A comparison with the measurements demonstrates that the simulation models capture the main dynamics. At the end of the paper, the load models are compared to a constant power load in a short-term voltage stability use case. The results indicate that the power electronic loads have a more positive influence on short-term voltage stability in case of voltage drops. Overall, the contributions of the paper are the identification of the basic power dynamics of power electronic loads for different voltage drops and a subsequent derivation of suitable simulation load models for voltage stability investigations.
