直流操作电源系统是变电站中的重要设备。为满足变电站无人值守的要求,直流操作电源系统需配置微机监控装置,其主要功能是实现电源系统的自动化管理、蓄电池组的最优化管理,并具备“遥信、遥测、遥控”功能,实现数据远传。在监控装置电路的设计中,应尽可能选择标准化器件、模块化结构的典型电路,应留有余地,以备扩展。并增加抗干扰能力,使整个系统具有自诊断和自恢复的功能。
DC operating power system is an important substation equipment. In order to meet the requirements of substation unattended operation, the DC operation power supply system needs to be equipped with a microcomputer monitoring device. Its main function is to realize automatic management of the power supply system, optimal management of the battery pack, and the functions of “remote signaling, telemetry and remote control” Far from the data. In the monitoring device circuit design, should try to choose a standardized device, modular structure of the typical circuit, should leave room for expansion. And increase anti-interference ability, so that the entire system with self-diagnosis and self-recovery function.
