摘要
配变监视仪(TTU)对配电变压器运行状态进行实时、全面监测,为计算供电可靠性、低压网损、控制电能质量等提供最基本的资料,也为配电网的改造、设备的增容及配电运行与管理工作提供准确的数据来源。PDA通过光电接口与TTU进行通讯,完成对TTU的参数设置及运行数据的抄录,同时可将抄录的各类数据通过微机串行口送入微机主站系统,由主站系统对数据进行处理。综述了TTU配变系统的硬件和软件的组成方案及其开发与应用。
Transformer Terminal Unit (TTU) monitors the running status of transformer entirely in a real-time manner to provide basic data for computing the reliability of power supply, and the losses of low-voltage network, and controlling the electricity quality. It also provides accurate data information for rebuilding the power network, increasing the capacity of the equipment, and managing the power supply. PDA connects with the TTU using the photo-electric interface, sets the parameters of TTU and records the running data of TTU. These data are transmitted to computer system via serial interfaces of the computer, and are processed by the main computer system. This paper describes the composition framework of TTU hardware and software, and its exploration and application.
