基于以太网的厂站同步监控系统
|
摘要
现代厂站微机监控系统在原有SCADA系统的基础上,采用了更为先进的传感测量控制设备,配备更为先进的网络通信设备,向着广域全网同步测量系统发展,功能应用延伸至状态估计、动态监测、故障分析等各个领域。
本文设计开发的微机同步监控系统由下位机数据采集系统、上位机数据服务系统及后台监控系统三大部分组成。数据采集系统平台由研华工控机及基于PCI接口的数据板卡组成,实现了可靠的数据采集和实时相量测量。采用具有应答机制的通信协议实现下位机和上位机数据服务器间的可靠通信,利用分布式组件技术设计了一个具有通用性、可扩展性的DCOM接口,使数据服务器能为后台监控系统及各种电力系统在线分析软件提供数据接口。在后台监控系统中,利用基本图元对象构建了发电机、变压器、负荷、线路等各设备单元,并建立了实时数据库和历史数据库,为实时动态显示变量曲线,历史信号、操作记录的存储管理,报表打印,离线数据分析等提供了数据支持。
本文将同步测量信号应用于发电机准同期并网中,提出了一种基于三相合成相量测量法和滑差分段恒加速预报模型的并网条件核算法。仿真结果表明:该方法较之传统的单相测量法和预报模型在快速并网时机获取及减小并网冲击上取得了更为满意的结果。
With the using of much more advanced technique of transducer, network communication equipment, modern power station microprocessor-based monitoring system is developed from primary SCADA system to Wide Area Measurement System which its functions spread into state estimation, dynamic stability monitoring, faults analyzing etc fields.
A microprocessor-based synchronized monitoring system is buildup by three part hypogyny data sampling system, epigyny data serving system and background monitoring system in this paper. Background monitoring system is composed of YanHua industry control machine and PCI based data boards which guarantees the sampling data reliability and implements the real time pharos calculation. The communication protocols with answering mechanism are adopted to ensure the high communication reliability between hypogyny computer and epigyny data server. A common and expandable DCOM interface is designed by using the distributed Component Object Model technique which provides the data interface for the data server and background monitoring system and other online analysis systems. Every device such as generator, transformer, load, transmission line and etc are constructed by fundamental metafile in the background monitoring system. Real-time and history database are build to offer data support for the dynamic curve displaying, history signal and controlling record storing management, reports forms printing, off-line data analyzing and etc.
The synchronized phasors are used for generator quasi-synchronize paralleling in this paper. The phasor measurement algorithm based on the compositive phasor of three phases and a forecasting model based on the subsection constant acceleration of slip frequency is proposed. The simulation results show that the better performance is achieved in fasting paralleling and reducing concussion compare to the traditional single phase measurements and forecasting models.
