Current standard EN 50463-2 indicates the tests and the requirements to be satisfied for an energy measurement system of a traction unit for railway applications. Some of these tests are to be done with several harmonics superposed on the rated voltage, respectively current. However, no calibration systems satisfying the standard requirements were available few years ago. The work performed in the EURAMET project "MyRailS" leads to the development of fictive power sources and reference measurement systems described in this paper. Therefore, it is possible to generate distorted 25 kV-50 Hz voltages with harmonics up to 5 kHz and 90° phase-fired currents up to 500 A with harmonics up to 5 kHz. The generated power is measured by developed traceable reference systems with accuracy better than 0.5%.
现行标准EN 50463-2规定了铁路应用牵引单元能量测量系统需满足的测试和要求。其中一些测试要在额定电压和电流上分别叠加若干谐波的情况下进行。然而,几年前还没有符合标准要求的校准系统。在欧洲计量研究计划(EURAMET)项目“MyRailS”中开展的工作促成了本文所述虚拟电源和参考测量系统的开发。因此,能够生成谐波高达5kHz、相位触发电流高达500A且谐波高达5kHz的25 kV - 50Hz畸变电压。所产生的功率由开发的具有溯源性的参考系统进行测量,测量精度优于0.5%。
