Abstract When using the railway static power conditioner (RPC) to solve the problem of power quality in traction power supply system, the compensation current of RPC will increase the voltage fluctuation of the two power supply arms to some extent, which may cause the under voltage or over voltage in the traction network. Under the premise of guaranteeing the effect of RPC comprehensive management, in order to effectively reduce the RPC compensation capacity and minimize the voltage fluctuation of the two power supply arms, in this paper, an RPC multi-objective optimization design method is proposed, which uses the voltage fluctuation degree of the power supply arm and the RPC compensation capacity as the optimization objectives. This paper analyzes the reasons why the RPC compensation current aggravates the voltage fluctuation of the two power supply arms, and introduces the voltage fluctuation index of the power supply arm. The multi-objective optimization mathematical model of RPC is established, and then solved by the multi-objective optimization algorithm of particle swarm optimization. The analysis and experiments verify effectiveness of the proposed method in reducing the voltage fluctuation of the two power supply arms and reducing the RPC compensation capacity.

Key words： Railway static power conditioner voltage fluctuation compensation capacity multi- objective optimization particle swarm optimization
