摘要
首先分析了广西电网厂站通信规约存在的不足,针对存在的问题扩充了遥测量有效位等参数,以及终端对电能表对时帧格式定义即时钟同步策略。为提高厂站电能量远方终端的检测效率和准确性,研制了厂站电能量远方终端检测平台,给出该平台的硬件和基于MFC的软件结构设计。平台支持多路多协议模拟表功能。该平台经磨合,对"电能表时钟异常"告警测试存在的告警上报轮次与预计不符,以及曲线数据测试存在的终端抄读曲线数据时间与模拟表不同步问题做了调整。调整后平台对各测试项均可准确判断,验证了其有效性。
In view of the shortcomings of the Guangxi plant power grid station communication protocol,the parameters of the effective bit of remote measurement are expanded,as well as the frame format definition and timing strategy of the terminal to the power meter.In order to improve the efficiency of the power terminal function and the consistency test of the communication protocol,a remote terminal detection platform for the station power energy is developed,and the platform is developed.The design of the hardware and software structure.The platform supports the analog table function of the 128 Road protocols,which can realize the protocol consistency of the station power remote terminal and the automatic test of data acquisition and alarm functions.The platform has been adjusted to adjust the data time of the terminal reading curve and the non synchronization of the simulation table when the test duration is too short and the curve data test exists.All the test items can be accurately judged by the adjusted platform,and the application and promotion can provide technical support to the quality of the product.
