介绍了一种基于北斗卫星系统的发电机进相运行稳定性的监控系统,包括北斗卫星系统模块、功角测算模块、参数辨识模块、接口转换模块、显示模块等,采用“考虑磁路饱和的本地发电机功角测算”与“基于系统戴维南等效的参数辨识”结合的方法,形成厂站端的进相运行稳定性监控系统,由于计及了饱和的影响及在线辨识系统参数,相对精度较高,可方便地嵌入到已有的发电机监测系统中,其中功角测算模块、系统戴维南等效参数辨识模块可方便地通过软件编程在已有的监测系统中加以实现。
A monitoring system based on the Beidou satellite system is introduced, which includes the Beidou satellite system module, the power angle estimation module, the parameter identification module, the interface conversion module, the display module and so on. Of the local generator power angle calculation “and” based on the system Thevenin equivalent parameter identification "method to form a station-side phase-in stability monitoring system, taking into account the impact of saturation and online identification of system parameters , Relatively high precision, which can be easily embedded into the existing generator monitoring system. The power angle estimation module and the Thevenin equivalent parameter identification module can be conveniently implemented in the existing monitoring system through software programming.
