Abstract

The invention relates to multi-load balance control system and method. The system comprises a power distribution circuit, a load balancer and a plurality of loads, wherein the load balancer is connected to a loop of the power distribution circuit; a current transformer for detecting a main current value of the power distribution circuit in real time is arranged on a main line of the power distribution circuit; the current transformer is connected with the load balancer; the detected main current value of the power distribution circuit is conveyed to the load balancer; the plurality of loads are respectively connected with a load switch controller; and each load switch controller is connected to the load balancer through a communication line and is used for receiving a control instruction of the load balancer and opening or closing the corresponding load. According to the multi-load balance control system and method, automatic dynamic control of load current backlash can be realized, so that the utilization rate of the total capacity of the system is put into full play; the multi-load balance control system and method can adapt to different load systems; load terminal equipment does not need to be calibrated in advance; frequent starting and stopping of the load terminal equipment are completely avoided; and the multi-load balance control system and method can automatically adapt to voltage fluctuation of the system.

Description

technical field [0001] The invention belongs to the technical field of load balancing power supply, and in particular relates to a multi-load balancing control system and method. Background technique [0002] In a power distribution circuit with a fixed maximum current, the total load current is limited by the total circuit breaker of the power distribution circuit, for example: if the total circuit breaker is 63A, the total load current is limited below 63A, If a load power changes or the number of devices connected causes the total current to exceed the limit, an overcurrent protection action will occur. In order to prevent this kind of failure phenomenon, the total number of devices connected to the power distribution circuit is usually artificially limited or adjusted, usually by connecting to a load balancer. The total current of the power distribution circuit is monitored in real time through the load balancer. If the total current of the power distribution circuit is...
