The design of automatic three phases load balancing for dynamic electrical installation

Abstract

This paper discusses the automatic design and simulation of The Three Phase Load Balancing in consumers’ three-phase electrical installations with a single-phase load. This approach solves many constraints of load imbalance, which is installed as a three-phase source for the consumers. The process of manually changing an electrical installation and adding new loads is very difficult. This load imbalance causes a one phase voltage source to be overloaded, while the other voltage sources are still not fully loaded. Implementing the automatic system makes the electrical installation dynamic, so that changing installation and adding new loads will be easier. The Automatic Three Phase Load Balancing comprises two types of control that integrate with each other, namely Central Controller and Unit Controller. The Central Controller is used as a data processor for overall loads. Several Unit Controllers are used as switches connection among phases in each load group. Based on the simulation results with MATLAB Simulink, this system can manage loads so that a balance is achieved in each phase. The more the number of load groups in an electrical installation, the better the load balance is obtained.
