基于无线传输参考相量的测量装置研制及应用

针对变电站现有相量测量装置对电压相量参考点有严重依赖性的问题,提出了一种以变电站一相运行电压为基准,无线发射覆盖全站,在站内使用可以接收无线参考电压相量的钳形相位表开展相量测试的装置。通过该成果在工程中的实际效果发现,本成果的测试精度高,测试结果准确、直观,测试方法简单,能够完全满足测试需要。同时,减少测试环节及工作人员数量,节省了测试的时间,提高了工作效率。

Development and application of measurement device forreference phasor based on wireless transmission

The present phasor measurement device of the substation has severe dependence on voltagephasor reference, a device was developed which is based on the one-phase operating voltage of thesubstation and covers the whole station by wireless transmission, and a clamp phase meter which canreceive the phasor of the wireless reference voltage is used to conduct phasor measurement in thestation. Through the actual effect of the results in engineering, it is found that the results of the testhave high precision, accurate and intuitive test results, simple test methods, and can fully meet thetest needs. At the same time, it reduces the number of testing links and staff, greatly saves testingtime and improves work efficiency.
