Description

technical field [0001] The invention relates to a smart grid power quality data monitoring device, in particular to a smart grid power quality analyzer. Background technique [0002] Power Quality, strictly speaking, the main indicators to measure power quality are voltage, frequency and waveform. Generally speaking, it refers to high-quality power supply, including voltage quality, current quality, power supply quality and power quality. It can be defined as: the deviation of voltage, current or frequency that causes electrical equipment to fail or fail to work normally, including frequency deviation, voltage deviation, voltage fluctuation and flicker, three-phase unbalance, temporary or transient overvoltage, Waveform distortion (harmonics), voltage sags, interruptions, swells, and power supply continuity, etc. [0003] With the development of the national economy and the improvement of people's lives, the requirements for power quality are constantly increasing, and the...
