摘要
介绍了C8051F020单片机和DS12887的特点和应用,给出了DS12887应用在无功功率补偿控制系统上的实例的主电路图和软件设计。C8051FO20性能优越,作为功补控制器的核心处理器能够出色地完成任务。DS12887精度高,稳定性良好,能够准确记录功补系统发生故障和功补支路投入或切除的时间,便于分析功补系统的运行情况和系统的维护。目前,该功率补偿控制器已经投入运行,且效果良好。
This paper introduces the trait and application DS12887,gives an example for the use of the power factor of the C8051F020 microprocessor and compensation system,and furthermore describes the hardware circuit and interface software.C8051F020 has good capability and can accomplish work independently as the core processor of power factor compensation controller.With high precision and good stability, DS12887 can memorize when the power factor compensation controller will go wrong and when it will throw on or off spur track,and it is helpful to analyze the status of the power factor compensation system and maintain it. Now, the controller runs well on the locomotive.
