| Abstract: | Merging unit (merging unit, MU), as the main physical carrier of smart synchronous phasor measurement unit (phasor measurement unit, PMU) data acquisition, its performance directly affects the accuracy of the measurement results. Aiming at the problem that the measurement error of the smart PMU device is out of tolerance, a test platform for measuring the measurement error of the smart PMU device is constructed, study on the factors affecting the measurement results of smart PMU device by merging unit. Finally, the key factors influencing the measurement error of smart PMU device and the degree of influence of various factors are determined. And puts forward some corresponding suggestions, it can provide some reference for the on-site inspection of smart PMU device. |
