有限集中式就地化母线保护方案

结合母线保护跨间隔的特点,提出了由基础保护系统加若干个扩展保护系统构成的有限集中分布式就地化母线保护方案。分别介绍了基础保护系统和扩展保护系统的功能,结合典型工程设计论证了每个保护系统的最优接入间隔个数,阐述了基础保护系统和扩展保护系统之间的通信方式及报文传输机制,提出了基于秒脉冲同步信号的采样同步原理,设计了基于标准端口定义的即插即用型航插的输入输出接口,给出了装置的站控层通信接口定义、过程层接口定义、装置的外观图及航插示意图,最后列举了有限集中分布式就地化母线保护的工程配置方案。

Railway Accident Prevention and Infrastructure Protection

Railway accident prevention and protection are a key part of a wider picture of transport safety. The rail sector thus needs to improve its knowledge of trespassing and suicide, including at level crossing, in order to work out suitable responses by analyzing measures already taken in various countries, Governments, the rail industry and road organizations have been implementing a variety of countermeasures for many years to improve railway safety. These actions are substantial and have resulted in a continuing decrease in the number and the severity of accidents. This paper presents existing suitable techniques that are used in the preventative measures targeted to reduce railway suicides, trespassing and level crossing user accidents. It describes them in terms of their capability to effectively reduce accidents, their cost-effectiveness and their integration within the railway transport system as a whole.
