Problems solved by technology

[0003] The former is not only troublesome, but also cannot be adjusted in real time; the latter needs to cut off the heavy load and then put it into the light load phase, which will generally cause disturbance to the load, and this shortcoming is difficult to overcome
In particular, the best potential of the power system cannot be brought into play in specific situations, and the existing detection parameters are not used to simplify the circuit

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, a load adaptive adjustment device, including 1 intelligent controller, 2 total load electrical parameter setting value, 3 total load electrical parameter measurement value, 4 random load balance degree setting, 5 each random load branch parameter detection , 6 each controllable load branch parameter detection, and 7-1 compensation balance module 1 to 7-2 compensation balance module L, 8-1 controllable three-phase load 1 to 8-2 controllable load M and 9-1 controllable load Control single-phase load 1 to 9-2 controllable load N.

[0017] When the load adaptive adjustment device is used for controllable loads, it controls 8-1 to 8-M three-phase controllable loads and 9-1 to 9 by comparing 2 total load active power setting values ​​and 3 active power measurement values - Switching of single-phase controllable loa...

Abstract

The invention provides an adaptive load adjustment device comprising a smart controller, a total load electrical parameter setting value, a total load electrical measured value, a random load, a controllable load and its power set value and measured value, a random load balance degree set value and a compensation balance module. Through the comparison of the set value and the measured value, the load and compensation balance module are controlled to balance the three-phase active power, equalize the actual power and set power, and optimize the power supply system load matching, thereby meeting the user requirements. The adaptive load adjustment device is simple in circuit, low in cost, and high in reliability.

Description

technical field [0001] The invention relates to the field of electric power supply network, in particular to a load adaptive adjustment system. Background technique [0002] The existing adjustment methods for unbalanced power loads are manual adjustments, or shifting heavy loads to light loads [0003] The former is not only cumbersome, but also cannot be adjusted in real time; the latter needs to cut off the heavy load and then put it into the light load phase, which will generally cause disturbance to the load, and this shortcoming is difficult to overcome. In particular, the best potential of the power system cannot be brought into play in a specific situation, and at the same time, the existing detection parameters are not used to simplify the circuit. Contents of the invention [0004] In order to solve the above-mentioned existing technical problems, the present invention provides a load self-adaptive adjustment system, which adopts the method of adding reactance t...
