Summary: | The invention discloses an inter-harmonic detection system of a three-phase active power distribution network. The inter-harmonic detection system comprises a three-phase current testing module, a module for transforming three-phase static coordinates to two-phase static coordinates, an inter-harmonic phase-locked loop circuit to be determined, a module for transforming the two-phase static coordinates to two-phase synchronous inter-harmonic frequency rotating coordinates to be determined, a low pass filter, a module for transforming the two-phase synchronous inter-harmonic frequency rotating coordinates to be determined to the two-phase static coordinates, and a module for transforming the two-phase static coordinates to three-phase static coordinates. The inter-harmonic detection system, provided by the invention, is very effective on the inter-harmonic voltage and the inter-harmonic current of a power distribution system. The invention is a system with simple structure, clear conception, and simpler dynami |
