Analysis of Improved Shipboard Power Flow Calculation Based on Component Modeling

A precise components modeling has a great influence on the power flow calculation. On the basis of the comparison with other algorithms, the backward-forward sweep power flow algorithm is chosen for the power flow calculation of the shipboard power system in the paper. Going with this algorithm, the six detailed component models are introduced, especially three phase transformer models are placed great emphasis on. To solve the problem of the matrix singularity and solution uniqueness, the symmetrical components method and the line-to line model is used in the transformer modeling. The proposed algorithm is tested with IEEE37 Bus, taking as a simplified shipboard power system. The validity, practicability and effectiveness can be demonstrated by the final results.
