Abstract:

In the variable frequency AC aviation power system, the power system should have the ability to carry the asymmetric load in certain situations. In order to verify the ability of dual stator-winding induction generator (DWIG) variable frequency AC power systems with asymmetric load, a new analysis method of asymmetric operation based on multi-port network load is proposed. First of all, the equivalent circuit of three-phase four-wire asymmetric load is deduced; secondly, the equivalent positive, negative and zero sequence circuit is put forward; thirdly, the asymmetric operation equivalent circuit of DWIG is obtained by combining the above two; finally the output voltage asymmetric degree is precisely calculated by solving the nonlinear equation. The quantitative analysis can be reached by the proposed method, meanwhile, the relationship between motor parameters and output voltage asymmetry is also obtained. The experimental results prove the correctness and effectiveness of the method and verify that DWIG has a good asymmetry load carrying capacity.
