The research of optimal control system of SVC for reactive compensation of single-phase load

摘要

It is an effective method to adopt Steinmetz circuit to eliminate the unbalanced three-phase components for reactive compensation in distribution networks. However, the compensation capacity for a three phase circuit with a single phase load is great. This article proposes an optimal algorithm with the target of minimizing the total compensation capacity, and designs a new type control system with a kind of FC-TCR SVC. The precondition for applying the optimal algorithm is analyzed, and then the analytical results are deduced. The dynamic simulations are carried on the platform MATLAB/SIMULINK and the results show that this algorithm has an obvious advantage in decreasing the compensation capacity without breaking the compensation claims.
