Abstract

The invention relates to a power quality detecting device with source power expansion. The device comprises a detecting device body and a power quality detecting unit arranged in the detecting devicebody. The detecting device further comprises a power quality compensation control unit. The power quality compensation control unit comprises a high-speed serial data interface which is arranged on the detecting device body and is connected with an external active power module, and a controller which is arranged on the detecting device body to transmit a control command to the high-speed serial data interface. The controller is connected with the power quality detecting unit and the high-speed serial data interface. Compared with the prior art, the device provided by the invention can rapidlycarry out function expansion, integrates power quality detection and compensation, and has the advantages of convenient use and reduced peripheral cost.

Description

technical field [0001] The invention relates to a power quality detection device, in particular to a power quality detection device with active power expansion. Background technique [0002] From the perspective of users, power quality refers to all abnormal disturbances in power supply voltage, current and frequency that will cause abnormal operation, failure or power outage of electrical equipment. In recent years, rectifiers, frequency conversion speed control devices, electric arc furnaces, electrified railways and various power electronic equipment in the distribution network have been increasing continuously. The nonlinearity, impact and unbalanced power consumption characteristics of these loads have caused serious pollution to power quality. . On the other hand, the electrical equipment of modern industrial, commercial and residential users is more sensitive to power quality, which puts forward higher requirements for power supply quality. The existing power detect...
