高速电气化铁路牵引站接入电网的工作原理探析

The Analysis on Working Principle of High Speed Electrified Railway Traction Station Connected to the Electricity Grid

高铁是推动地区经济发展的重要动力,高速铁路已成为国家重点建设的基础项目。然而高速铁路的建成将对电网造成一定程度的影响,为此对高速电气化铁路牵引站接入电网的电能质量环境进行分析具有重要的意义。首先阐述了相关电能质量标准、高速铁路牵引供电方式及负荷特征,然后分析了高铁牵引变电站的特性。

High-speed rail is an important driving force for economic development in the region, high-speed railway has become the basis projects for national key construction.However, high speed railway which in turn will cause a certain degree of influence to power grid,therefore the high-speed electrified railway traction station connected to the electricity grid power quality environment analysis is significant. First elaborated the relevant power quality standards, high-speed rail traction power supply and load characteristics, then detailed study the high-speed railway load power quality of grid environment, came to the high speed railway load power quality of grid environment has a large number of harmonic,nonlinear,impact and volatility, and other important conclusions.
