Electric energy quality comprehensive optimization control system and method for low-voltage power distribution network

Abstract

The invention relates to an electric energy quality comprehensive optimization control system and method for a low-voltage power distribution network. The electric energy quality comprehensive optimization control system for the low-voltage power distribution network comprises an optimization control module which comprises a control unit and an effect inspection unit, wherein the control strategies for solving various electric energy qualities is stored in the control unit, the effect inspection unit is used for inspecting the treatment effects of the control strategies, judging whether the treatment effect reaches an expected standard or not and ending the control of the control system if the treatment effect reaches the expected standard, if the treatment effect does not reach the expected standard, the control unit continuously outputs the related control strategies until the treatment effect reaches the expected standard, and the control is ended. A plurality of compensation modules are dispersed at different positions of a same power distribution area, and each compensation module is used for carrying out related compensation on the low-voltage power distribution network according to the control strategy. According to the present invention, various electric energy quality problems at various positions of the low-voltage power distribution network can be solved.

Description

technical field [0001] The present application relates to the field of power grid technology, in particular to a comprehensive optimization control system and method for power quality of a low-voltage distribution network. Background technique [0002] In the low-voltage distribution network, affected by factors such as single-phase power consumption time differences, uneven load distribution, and irregular load growth, three-phase imbalance problems occur from time to time. The three-phase unbalance problem seriously restricts the output of the transformer, causing problems such as increased transformer loss and overload damage. In addition, it causes increased loss of distribution lines and even low voltage problems, which seriously affects the operation safety of the low-voltage distribution network and reduces the operation of the distribution network. Efficiency; In addition, with economic development, more and more nonlinear loads, harmonic and reactive power problems ...
