京九电气化铁路对阜阳电网的影响
|
摘要
随着经济发展的需求,电气化铁路已成为当前我国重点发展的交通方式,但是,由于电力机车负荷的大功率性和不对称性,而且具有复杂和随机的运行状态,投入运行后会产生大量的负序电流,引起电网三相不对称;另外,由于电气化铁路的负载是典型的非线性负载,会产生谐波并引起电压波形的畸变以及功率因数低等现象,因此,分析电气化铁路对电网的影响,并提出相应的管理措施,可以使电力系统更加稳定、安全、经济地运行。
本文主要以安徽省阜阳电网及京九电气化铁路为研究对象。首先,简述阜阳电网现状及京九电气化铁路牵引站供电方式,然后,对电力机车进行谐波分析,建立电铁牵引负荷的谐波源模型和输电线路、变压器等电力系统元件在不对称情况下的谐波模型,计算电力系统元件在不同频率时的等值电路参数,并采用相分量法,给出了含电铁牵引负荷时,电力系统不对称基波潮流与谐波潮流的计算方法。最后,针对阜阳电网局部进行了谐波和负序的计算,根据计算结果,分析了谐波和负序对继电保护的影响、谐波引起的附加电网损耗等,并提出了针对性的综合管理措施,进而可以减小电气化铁路对阜阳电网的影响。
With the development of the economic needs, the electrification railroad is a key stonedevelopment traffic in our country, however, the electric locomotive load is asymmetricalwith high-power, also has the complex changeable running status and randomness, when itworks, massive negative sequence current can be produced, and also lead to the emergence ofthree-phase power grid caused asymmetry, harmonics generated from the voltage waveformdistortion; and the Phenomenon of low Power factor. Therefore, analysis the effect on electricfence of the electrified railway can make sure the power system more stable, security andeconomical operation.
This passage mainly studies on objects of Fuyang electric fence and electrified railways in Anhui Province，analysis the current situation of Fuyang electric fence and power supply mode of Beijing-kowloon electrified railways’sites. Then analyzed the influence of electrical railway traction load to Fuyang Power system.The mathematicmodel of electrical railway traction Ioad is developed. The harmonic and asymmetry modelsof elements of Power system are also developed. Based on these studies，calculatingasymmetry load flow and harmonic current with electrical railway traetion load is developed.The solution is used to calculate the harmonic current in Fuyang Power system.With the calculating results the influence of harmonic to relaying protection，automatic control.Enhance the quality of the power, and also to create a favorable electric environment and promote the development of local economic.
