【摘要】：直流电源系统在电力系统中有非常重要的作用，它通常是指由蓄电池、变流器以及其它辅助电路组成的供电系统。在提供直流电源供电的区域，他们要求直流电源能够运行稳定，更高的要求是工作中调节方便，并能对其进行远程监控。本文基于乌海地区变电站直流电源监测系统现状，深入研究和分析直流电源远程监测系统的关键技术，对原直流电源蓄电池系统进行改造，实现对其远程监控，提高变电站直流电源系统的自动化水平、完善其功能，增强直流系统运行的安全性和稳定性的目的。在电力系统中，直流电源系统是变电站的重要组成部分，也关系到电气设备的操作与控制。由于直流系统设备繁多，分布分散，经常需要维护和监测，本文提出了一种直流电源智能化在线远程监测技术，能够实现将蓄电池组各个工作模块的实时数据采集并传回控制中心。该方案不但能够大大降低维护人员的工作量，，同时能够对直流设备实时监测，能够随时把握蓄电池组的工作状态，提高了变电站整体运维水平。在本文中，对系统监控终端软件和子站监测通信模块进行设计，通过监控终端能够监控和浏览所有现场数据，通过直流系统模拟图观察直流设备运行状况，并且能够远程调控母线电压的状态切换，观察电池温度及充放电情况，电池电压和电流可以通过表格形式形成数据图，查看历史数据进行对比，能够通过监控软件更改现场模块参数等。
[Abstract]:DC power system plays an important role in power system. It usually refers to the power supply system composed of battery, converter and other auxiliary circuits. In the area where DC power supply is provided, they require DC power supply to run stably, and the higher requirement is that it can be adjusted conveniently and can be monitored remotely. Based on the status quo of DC power monitoring system in Wuhai substation, the key technology of DC power remote monitoring system is deeply studied and analyzed in this paper, and the original DC power battery system is reformed to realize remote monitoring. The purpose of improving the automation level of DC power supply system in substation, perfecting its function and enhancing the safety and stability of DC system operation. In power system, DC power supply system is an important part of substation, and also relates to the operation and control of electrical equipment. Because the DC system has a lot of equipments and distributed, it often needs maintenance and monitoring, this paper presents a kind of intelligent on-line remote monitoring technology of DC power supply. It can collect the real-time data of each working module of battery group and send it back to the control center. This scheme not only can greatly reduce the workload of maintainers, but also can monitor the DC equipment in real time, grasp the working state of the accumulator at any time, and improve the operation and maintenance level of the substation as a whole. In this paper, the system monitoring terminal software and sub-station monitoring communication module are designed, through monitoring terminal can monitor and browse all the field data, through the DC system simulation diagram to observe the operation of DC equipment. And can remotely adjust and control the bus voltage state switch, observe the battery temperature and charge and discharge situation, battery voltage and current can form data graph through tabular form, check the historical data to compare. Be able to change field module parameters by monitoring software.
