| In power systems, data transmission and scheduling of traditional plant station master terminal, remote communication is only one way, depending on remote information points table, by DNP CDT,101/104transmission protocol. PMU based Wide Area Measurement System (WAMS) will become the power system on-line analysis, the basic platform real-time monitoring and control. To achieve data exchange and sharing between WAMS system with other systems, based on the Common Information Model (CIM) extension lead the establishment of WAMS data model, and on this basis, combined with IEC61970-404High-speed data (HSDA) standard, gives a data exchange framework includes general design data exchange and data subscriptions WAMS data exchange program, which enables WAMS system effective integration with other applications, and allow other applications to access WAMS data. In the power station,using alarm collection module of substion graphic gateway server,directly collects the data of predictor and protection device in spacing level by specification protocol,by TCP establishes connection with alarm receiving module of dispatching center main station,realizes"over real network sharing" of real time data,real time picture and real time performance.The State Grid Corporation of the "Da Yun Xing" system of regulation is required to achieve integration, dispatch services and equipment monitoring mission integration, which require the transmission of large amounts of substation data, significantly increasing the processing load on the master system database. For this purpose, the National Electric Power Dispatching Control Centre proposed a "warning Direct, remote viewing," new data interactively and started a pilot, in order to resolve the problem of substation data transmission and processing surge brought..This article obtains from the most basic agreement, both the client and server configuration, respectively, to realize the alarm direct passing the basic function and remote viewing. Should be equipment for substation information in real time optimization, the alarm information sent directly to the control center of the master station system, changed the past need to create a way to find the alarm database in master station system, reduces the amount of maintenance. Master station system by receiving the optimized real-time data and alarm information equipment, as well as using remote browsing tool can realize remote monitoring of substation equipment, operational station, can be used by receiving equipment alarm information and remote viewing tool such as implementation of substation equipment remote operations. |
