摘要：
Unbalanced loads are quite common in a three-phase network and this is one of the major causes of voltage unbalance in low voltage distribution networks. The traditional three-phase compensators are mainly used for reactive power elimination without the neutral current elimination while the susceptances calculation are also based on the load admittance which is difficult to measure. A hybrid compensator containing star and delta segments can be used for neutral current elimination, load balancing and power factor improvement. In this paper, a mathematical model is derived based on the phase and sequence components of the load current using symmetrical components theory for load balancing, power factor correction and neutral current elimination. The validation of the proposed model is done through MATLAB simulation.
