Research on distributed power integration and management of railway power system

铁路系统的电气化提高了火车运行速度、稳定性,满足了更多的客运和货运需求,但是由于特殊的火车电力牵引系统导致铁路电力系统存在电压稳定性和无功损耗的问题。文中提出一种通过分布式电能集成与管理实现电压稳定控制和无功优化的模型。所提出模型构建了分布式多区域电能控制网络,开发了经济电压和无功功率灵敏度分析方法和自适应电能储备方法,并提出一种面向无功优化和保持良好电压分布的多目标优化问题。仿真结果表明,该模型可以在改善电压分布的同时降低功率损耗。

In view of the unstable power quality in railway power systems,this paper presents a model of voltage stability control and reactive power optimization through distributed power integration and management.The proposed model constructs a distributed multi-area power control network,develops economic voltage and reactive power sensitivity analysis methods and self-adaptive power reserve method,and achieves a reduction of reactive power loss and maintains good voltage by proposing a multi-objective optimization problem.distributed.The simulation results show that the model can reduce the power loss while improving the voltage distribution.
