摘要

50赫兹的铁路负荷，通常由两相传输系统提供，代表了不平衡的可能来源。不平衡的渗透在很大程度上取决于电力系统的刚度和本地、公共网络的连接。本文介绍了芬兰两个不同地区铁路负荷引起的不平衡现象。凯努代表了一个传输系统相对较弱和重型矿石列车的农村地区。相反，赫尔辛基市区有一个僵硬的传输系统，火车的负荷比例相当小。这些极端的芬兰电力系统特性导致凯努的不平衡值相对较高，而赫尔辛基的不平衡值相对较低。

The impact of 50 Hz railroad systems on utility system unbalance

50 Hz railway loads, typically supplied by two phases of the transmission system, represent a possible source of the unbalance. The penetration of the unbalance is highly dependent on the stiffness of the power system and connections from the local, public network. This paper presents observations of the unbalance caused by rail loads in two various Finnish areas. Kainuu represents a rural area of a relatively weak transmission system and heavy ore trains. On the opposite, Helsinki urban area has a stiff transmission system and train loads are proportionally considerably minor. These extreme Finnish power system characteristics result in relatively high unbalance values in Kainuu and lower values in Helsinki.
