摘　　要：对于传统系统普遍存在的检测精准度低问题,提出了基于负荷分类的台区线损数据快速检测系统设计。根据影响线损电流、电压、负荷曲线、电气设备、电力规划与电网安全的指标来说明数据来源,依据台区线损计算原理,对系统总体结构进行设计。以工作主站为硬件核心,设计C/S分布式处理服务器,保证用户界面完整性。采用模块组合方式,根据不同用户对终端系统进行配置,以32位单片机为主设计客户终端,保证检测可靠性。设计通用分组无线服务网通信电路,利用RS232接口与主机相连接,以此对软件进行现场维护。将系统软件划分为存储层、处理层和表示层,可实现系统终端参数维护,根据台区线损计算范围,确定线路分段数与电阻值。通过计算台区总线损,获取线损精准数据,由此实现线损数据快速检测。由实验结果可知,该系统最高检测精准度可达到95%,为台区稳定供电提供支持。To solve the problem of low detection accuracy in traditional system,a design of line loss data fast detection system based on load classification is proposed.The data sources are illustrated according to the indices affecting line loss current,voltage,load curve,electrical equipment,power planning and power grid security,and the overall structure of the system is designed according to the principle of line loss calculation in stations and regions.Taking the master station as the core of hardware,the C/S distributed processing server is designed to ensure the integrity of user interface.The terminal system is configured according to different users by modular combination,and the client terminal is designed with 32-bit single-chip microcomputer to ensure the reliability of the detection.The communication circuit of general packet radio service network is designed,and the RS232 interface is used to connect with the host computer to maintain the software on the spot.The system software is divided into storage layer,processing layer and presentation layer,which can maintain the terminal parameters of the system.According to the calculation range of line loss in the station area,the number of line segments and the value of resistance are determined.The accurate data of line loss can be obtained by calculating the bus loss in the platform area,thereby realizing the fast detection of line loss data.The experimental results show that the highest detection accuracy of the system can reach 95%,which provides support for stable power supply.
