新型数字化变电站长录波系统设计

现有的录波分析软件多为C/S架构,兼容性较差,客户端软件升级与服务器维护易给用户带来使用不便。随着网络发展,电力系统运行管理趋于网络化,本系统采用B/S架构,顺应了这一趋势。本系统服务器可通过TCP/IP协议同时接收协议转换器转发的常规存储卡、基于IEC61850-9-1标准的采样值和遵循IEC61850-8-1标准的面向通用对象的数字化变电站事件（GOOSE）等三种数据报文,排除硬件上的差异,从而实现录波数据的快速采集、高效启动判断、综合分析处理与保存,通过Web发布以供用户远程浏览信息及波形,下载文件,很好地满足了数字化变电站对录波系统的新要求。

System Of Newly-designed Persistent Wave Recording in Digital Substation

The existing wave-recording analysis software is mostly implemented with C/S architecture, whose compatibility is poor, and client software upgrade or server maintenance is not convenient for users. As the network development, power system management tends to be networked. This system is based on B/S architecture, conforming to the trend. The innovation of this system is that server can receive three kinds of data message based on general storaging card, sample value accord ing to standards of IEC61850-9-1 and object-oriented substation affairs （GOOSE） following standards of IEC61850-8-1 which the protocol transforming equipment transmits by the protocol of TCP/IP. It eliminates the difference of hardware, thereby implements quick acquisition, efficient start up judgment, comprehensive processing and storage of the wave recording data, providing the customer with browsing information and wave shape over Internet, downloading files by the Telnet protocol.
