Study And Design On Half Core Reactor

Power reactor is one of the important power equipments in power system and extensively used to compensate capacitive current, limit switching surge current and short circuit current, filter harmonic current, smooth De, block communication wave and lightning wave. In this paper, the classification and used method of the power reactor is introduced and a new basic design idea of the half-core reactor is present according to the basic structure of the half-core reactor in today power industry.The half-core reactor is a new type power reactor based on complex electrical-magnetic calculation method. A reasonable structure and a electrical-magnetic model of half-core reactor is proposed. A new calculation method of branch resistance in the half-core reactor using FEM and surface current method is present and researched. A design software of the half-core reactor based on branch voltage-current equations is completed. The design software is effective proved by comparing with experiential result. The calculation error is lesser than 0.8%, so this paper has significance directive function for the design of the half-core reactor.
