多线程技术在变电站保护信息监测系统中的应用

Research and exploitation in multiply threads technology on system of supervising protective information of transformer substation

针对某变电站对保护信息监测的实际需求,提出了“变电站保护信息监测系统”的总体设计思路,并就其实现方法进行了探讨和研究。系统由主站系统与若干个子站系统组成,子站系统与保护及故障录波系统相接并完成协议转换,同时将数据上传到主站。它有效地解决了变电站设备的集中管理和设备数据的综合处理问题,尤其对电网的故障处理和分析有较高的实用价值。

Aiming at the practical demands of some transformersubstation in supervising the protective information, the whole devising thoughts is provided and a lot of research and discussion is made to achieve it. The system is made up of several substations and a main station, The substation may connect with the system of protecting and recording the wave of malfunction and complete the protocol trans- lation. Meantime the data are transmitted to the main station. The system, which may efficiently resolve some problems, such as centralized managementofequipments, integrated disposal of the equipmentdata, particularly analyzingand dealing with the malfunctions in the electrical net, is highly useful in reality.
