基于分布式变电站电量测控系统设计
摘要变电站作为电能的集中和分散点，提高其供电的可靠性，是解决持续供电问题的关键所在。对于那些通过上位机对现场设备进行监控的工厂、变电所，准确可靠的监控数据对他们尤为重要。所以本文着重研究了的变电站智能电量测控系统的实现。
本课题主要利用I-7000系列测控模块自动遥测并实时显示变电站一次系统中电流、电压、功率因数、有功功率，无功功率，频率等电量参数值来反映系统的运行情况；利用RS-485现场总线联网技术将电量参数遥测电路、电量参数预处理电路、开关状态遥信电路等测控模块组网，通过微机对断路器等远程控制开关装置进行远动控制；并可通过功率继电器输出模块对各开关设备遥控合/跳闸，或根据需要控制一次系统的运行模式。63897

Title Power monitoring and control system for substation based on the distributed
Abstract As acentralized and decentralized point of power, Enhancing the reliability of power supply the substation is a keypoint for continuous power supply problem.The factory orsubstation which use the PC to supervising and controlling the equipment, the accurate andreliable of the data is rather important.So this thesis mainly research the realization of Inelligent power monitoring and control system for substation.
This subject mainly uses the I-7000 series control modules automatically telemetry and display the power parameter values of current, voltage, power factor, active power, reactive power, frequency, etc. in the first system of the substation on real-time to reflect the operation of the system; The system uses the RS-485 fieldbus networking technology to combine the power parameter telemetry circuit, the power parameters pre-processing circuit and the switch status remote signaling circuits into a network. It uses the computer to control the remote control circuit breakers and other switchgear to realize remote control .It can also control the the switch device on / trip through the power relay output module or the operation mode of the system acording to the demand.
Keywords Remote control Remote communication Remote telemetry Bus networkin
