Abstract

The invention discloses a comprehensive power quality control system which comprises a monitoring terminal system which comprises a positioning module, of which the output terminal is electrically connected with the input terminal of a signal transmit-receive module. The input terminal of the signal transmit-receive module is electrically connected with the output terminal of a buffer memory module, and the input terminal of the buffer memory module is electrically connected with the output terminal of a monitoring unit. The output terminal of the buffer memory module is electrically connected with the input terminal of a display module, and the output terminal of a monitoring terminal system is electrically connected with the input terminal of an alarm system. The output terminal of the monitoring terminal system is electrically connected with the input terminal of an automatic power-off module. According to the comprehensive power quality control system, a photovoltaic generating unit uses sunlight for generating power, thereby preventing influence on the monitoring terminal system due to receiving power from the power grid. The information acquisition accuracy is further improved, and the influence and interference of power quality due to extraneous force can be reduced.

Description

technical field [0001] The invention relates to the technical field of power control, in particular to a power quality comprehensive control system. Background technique [0002] Power quality is the quality of power in the power system. The ideal electrical energy should be a perfectly symmetrical sine wave. Several factors can cause the waveform to deviate from a symmetrical sine, thus creating power quality problems. On the one hand, we study which influencing factors will lead to power quality problems, on the other hand, we study what problems these factors will cause, and finally, we need to study how to eliminate these factors, so as to maximize the power close to the sine wave. [0003] At present, most of the existing equipment in the power grid, such as reactive power compensation, is capacitor compensation, which has been widely used because of its simple structure. However, the general shunt capacitor bank is used in the occasions where the load is relatively ...
