Reactive compensation intelligent monitoring management system

Abstract

The invention discloses a reactive compensation intelligent monitoring management system comprising a signal acquisition module (1), wherein the signal output end of the signal acquisition module (1) is connected with the signal input end of a signal processing module (2); and the signal output end of the signal processing module (2) is connected with the signal input end of an execution module (3). The invention has the remarkable benefits that a power grid achieves the ideal balanced compensation effect by reasonable switching of a capacitor; the power self consumption of a compensation device is reduced to be minimized by inrush current-free input of the capacitor; and the health condition of the system equipment can be monitored and judged in real time and the effect of reactive compensation can be known.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an intelligent monitoring and management system for reactive power compensation. [0002] Background technique [0003] At present, on the low-voltage side of the public transformer of the urban distribution network, due to the continuous increase in the inductive load of household appliances, the power factor is low, resulting in large line losses on the low-voltage side of the public transformer. Statistical domestic urban and rural reactive power loss is divided according to voltage level: 0.4KV level loss accounts for 50%, 10KV level accounts for 30%, and 35KV and above accounts for 20%. Therefore, it is of great significance to do a good job in reactive power compensation below 10KV level voltage. [0004] In recent years, due to the development of computer technology, reactive power compensation technology has been greatly improved, and the development of reactive power compe...

AI Technical Summary

Problems solved by technology

When the three-phase current of the load is unbalanced, the three phases cannot be well compensated, which may cause one phase to overcompensate and the other phase to undercompensate

When switching capacitors, the power factor is often used as the criterion, which is prone to frequent switching at light loads, and insufficient reactive power compensation at heavy loads
