Abstract This paper focused on a railway negative sequence control system to deal with the negative sequence related problems in electrical railway power system. Its universal three-phase model is proposed firstly. Besides, an integrator associated linear quadratic controller and its related voltage balance controller are also presented in this paper. In the premise of getting good compensating performance, the system can significantly enhance the controlling flexibility and the calculating efficiency. Moreover, the perturbations from output voltage and the coupling inductance of the main transformer can also be overcome as well. Finally, simulation and experimental results validate the correctness of the conception.

Key words： Electrical railway negative sequence universal three phase frame integrator associated linear quadratic controller voltage balance
