摘要：This article mainly introduces the application ofreactive power detection theory in reactive current andharmonic current detection. In order to detect harmonics andreactive currents quickly and accurately, this article proposesthree detection methods: p-q detection method based oninstantaneous reactive power theory, p q i 儃i detection methodand d-q decomposition detection method. Then throughsimulation experiments under the conditions of undistortedvoltage, distorted voltage, and unbalanced three-phase voltage,these three current detection methods are introduced andanalyzed, as well as their detection accuracy, speed, delay,real-time performance, and applicable occasions. The resultsshow that the d-q decomposition detection method can performaccurate and effective detection under various conditions.
