Experimental data for a low-head contra-rotating reversible pump-turbine

Hydraulic data recorded at the Leichtweiß-Institute for Hydraulic Engineering and Water Resources contra rotating reversible pump turbine (CR-RPT) test rig. The test rig consist of two open surface water tanks, connected by a pipe in which the CR-RPT is installed. The gross head difference is constant and 7.8 m. The CR-RPT includes two runners with a diameter of 276 mm, each powered by different electric machines. The data was recorded from pressure transducers (pressures), flowmeter (flow rate), torque transducers (torque) and enconders (rotational speed). The test rig aims to simulate the working conditions of a low-head pumped hydro energy storage station.本数据集为莱希特魏斯水利工程与水资源研究所（Leichtweiß-Institute for Hydraulic Engineering and Water Resources）在对旋式可逆水泵水轮机（contra rotating reversible pump turbine，CR-RPT）试验台上采集的液压数据。该试验台由两个开敞式水箱组成，二者通过输水管道相连，对旋式可逆水泵水轮机即安装于该管道中。系统总水头差恒定为7.8米。该对旋式可逆水泵水轮机包含两个直径为276毫米的转轮，分别由独立电机驱动。本次记录的数据来源包括压力传感器（pressure transducers，采集压力信号）、流量计（flowmeter，采集流量数据）、扭矩传感器（torque transducers，采集扭矩信号）以及编码器（encoders，采集转速信号）。该试验台旨在模拟低水头抽水蓄能电站的实际运行工况。
