Application and simulation analysis of electromagnetic balancing technology applied in Efficiency Power Plant

In three-phase four-wire distribution power system, the loads are not balanced because of optional running, uncertain capacity and unpredictable kinds. Unbalanced power distribution system leads great transmission lines loss. Electromagnetic balancing technology can improve unbalanced phenomena in three-phase four-wire system dynamically, and reduces transmission lines loss to get the goal of saving energy. Electromagnetic balancing technology is partly composed of Efficiency Power Plant (EPP). If electromagnetic balancing technology is widely used, EPP can be constructed efficiently. Electromagnetic balancing technology theory is discussed in paper, some data is used to test the theory. An actual instrument is produced to apply in distribution system, the measured electrical data in field shows that electromagnetic balancing technology is effective. At last, results simulated by SimPowerSystems/MATLAB and actual data make the following conclusions: a. improving unbalanced status of three-phase four-wire distribution power system; b. reducing neutral line current and restraining harmonic components. c. decreasing the loss of distribution transformer, 10kV transmission lines and 380V transmission lines. Experimental data and simulation results show that electromagnetic balancing technology is efficient and practical in distribution network, as well as the distribution network based on distributed energy-efficient power plant construction is feasible.
