摘要(Abstract):

智能变电站由于采用IEC 61850标准,继电保护及相关装置通信信号关联都依赖系统配置文件。然而系统配置文件是基于XML(可扩展标记语言)的复杂计算机语言,普通用户难以掌握,因而带来很多运维问题,例如装置消缺依赖厂家、间隔扩建时修改母线保护配置需要全停传动、配置文件不受控等。为此,分析了智能变电站继电保护配置的需求,提出智能变电站基于通信链路参数设置的免配置文件技术方案,避免了继电保护对配置文件的依赖,消除了间隔扩建修改母线保护配置全部传动的问题,并给出一个应用示例。
Due to the adoption of IEC 61850 standard in smart substations, the communication and signal correlation of relay protection and the related devices rely on the system configuration file. However, the system configuration file is a complex computer language based on XML(extensible markup language), which is difficult for ordinary users to grasp and brings problems to smart substation operation and maintenance: defects elimination depends on the manufacturer, the bus protection configuration needs full drive stop during one bay expansion, the configuration file is not controlled and so on. Therefore, the requirement of relay protection configuration in smart substations is analyzed, the technical scheme free of configuration file based on communication link tuning in smart substations is proposed, which avoids the dependence of relay protection on the configuration file and eliminates full drive stop for busbar protection during bay expansion. Finally, an application example is given.
