供电质量提升技术测试数据集

分布式光伏逆变器谐波及不平衡测试数据集包括了研发过程中谐波影响机理分析模型数据，以及逆变器在交流电压为0.85pu、1.15pu下测试的三相电压、电流、有功功率、无功功率、视在功率、功率因数、频率等相关测量；特别的，在正常标称电压下，额外给出了三相电流的THD值、负序分量、以及各次谐波幅值。测试设备为功率分析仪PA8006，采集频率为5Hz。该数据集中0.85pu和1.15pu交流电压测试的重点为逆变器输出的电压、电流、功率等情况，确保能够平稳运行，无振荡失稳现象，以说明交流电压工作范围(85%~115%)UN。；数据集中标称电压下谐波不平衡测试的重点为三相不平衡程度、三相电流THD及各次谐波幅值，确保逆变器可主动抑制30 次以内电流谐波及三相电流不平衡度≤2%。数据量约为35MBThe distributed photovoltaic inverter harmonic and imbalance test dataset includes the data from the harmonic influence mechanism analysis model during the research and development process, as well as relevant measured parameters such as three-phase voltage, current, active power, reactive power, apparent power, power factor and frequency when the inverter is tested under AC voltages of 0.85pu and 1.15pu. Specifically, under the normal nominal voltage, the Total Harmonic Distortion (THD) value of three-phase current, negative sequence component and the amplitude of each harmonic order are additionally provided. The test equipment used is the power analyzer PA8006, with a sampling frequency of 5 Hz. The key focus of the AC voltage tests at 0.85pu and 1.15pu in this dataset is the output voltage, current, power and other operating conditions of the inverter, to ensure stable operation without oscillation or instability, so as to verify the AC voltage operating range (85%–115%) of UN. The core focus of the harmonic and imbalance test under nominal voltage in this dataset is the three-phase imbalance degree, three-phase current THD and the amplitude of each harmonic order, to ensure that the inverter can actively suppress current harmonics within the 30th order and limit the three-phase current imbalance degree to ≤2%. The total data volume of the dataset is approximately 35 MB.
