变电站远动机串行接口分路装置设计与应用

根据电力调度自动化系统提出的升级改造需求,要求将还未接入地调和备调系统的站点通过调度数据网接入地调和备调系统,并实现多调度系统一体化。但一些变电站正在使用的远动机没有足够的接口,无法同时接入到多个调度系统。为此,通过分析调度主站和变电站远动通信规约工作模式,设计了一种串行接口分路装置。将装置连接到变电站远动机上,即可实现远动机与多个调度自动化主站系统实时通信。分路装置的应用使变电站在不更换远动机的情况下,实现多个调度主站对变电站的实时监测与调度,通过测试和试点运行,表明其能够满足电力调度系统一体化的接入需求。

Design and implementation of serial interface shunt device for substation remote engine

According to the upgrade and transformation requirements put forward by the power dispatching automation system, it is required to connect the site that has not yet been connected to the local tuning and tuning system to the localization and adjustment system through the dispatching data network, realizing the integration of the multi-scheduling system. However, some remote engines that are being used in substations do not have enough interfaces to access multiple dispatch systems at the same time. To this end, a serial interface shunt device is designed by analyzing the working mode of the telecontrol communication protocol of the dispatching master station and the substation. By connecting the device to the substation''s remote engine, real-time communication between the remote engine and multiple dispatching automation master stations can be realized. The application of the branching device enables the substation to realize the real-time monitoring and dispatching of the substation by multiple dispatching main stations without replacing the remote motives, meeting the integrated access requirements of the electric power dispatching system through testing and pilot operation.
