【摘要】 随着国民经济的发展，电气化铁路必将随之增加．铁路电气化必须有足够的电力来支撑．电力机车不仅用电量大，而且由于其负荷的特殊性，对相关电厂运行的安全性将产生重大影响，这是铁路电气化给相关电厂带来的新课题．本文在分析电力机车产生负序电流的基础上，通过典型实例计算，表明电气化铁路对相关电厂运行安全性所造成的影响，从而提出相应对策．更多还原

【Abstract】 With the development of the national economy, the electric railway, whose electrification can only be realized with enough power, is destined to be used. Not only will the large power consumption of the engine but the particularity of it’s load be important to the safe running of relative power plant which is a new subject of power plant brought about by railway electification. Based on the analysis to the problem that the electric railway produces negative-phase-sequence current, this article indicates the influence on the running safety of relative power plant by the electric railway through caculations in the typical examples, so as to bring about relevant solutions.更多还原
