And the traditional passive filter's function is also limited for avoiding the resonance and harmonic enlarging. The auto-compensator and harmonics shielding converter transformer can be used to solve these problems, which is based on the principle of the winding ampere and turn's balance. This paper elaborates this kind of transformer filter mechanism. In the view of the HVDC system, a new winding connection plan is proposed, and the filter optimization model is created.

The major works are as follows: 1 The 3-D numerical model of U-sharp flow passages is set up. The single-phase fluid flow and heat transfer are simulated for the U-sharp smooth and rib-roughened flow passages with FLUENT software. Their performance curves, temperature field and velocity vector are obtained and the local heat transfer and flow pressure-drop distribution along flow passage are analyzed. It is revealed that the ribbed flow passages can enhance heat-transfer and make the temperature more uniform, but it increases the pressure-drop to more extent. 2 The influences of diaphragm depth, channel width and board spacing on the performance are investigated.
