چکیده
Abstract: In modern power systems, high-precision power parameter measurement has occupied an important position for power quality in power grids. This paper presents a high-precision intelligent power parameter measurement device, which can collect parallel alternative current parameter values among 0 to 250 V in 3-channel easily and quickly, and improve the measurement accuracy by using the power spectral correction algorithm for sample parameters. The ATT7022B chip is used as the front-end of the data acquisition, and we use STM32 chip as the processor, which is easy to implement the algorithm on this platform. Results obtained from test application of the entire system show that the system has advantages of stable performance, small size, high reliability, and excellent accuracy.
