摘要
随着智能变电站逐渐在电网公司推广和应用,变电站直流系统也亟需实现远程控制充放电。针对上述问题,文中基于并网逆变技术原理,协同通信技术以及信息化技术,研究变电站直流系统的远程充放电控制策略。文中所提出的控制策略改变了人工使用电阻箱的方法,实现了充放电的远程控制和在线实时监测。该策略符合智能化与信息化的要求,为推广远程充放电技术提供了有力保障。
As smart substations are gradually promoted and applied in power grid companies,substation DC systems are also in need of remote control charging and discharging. In view of the above problems, this paper studies the remote charge and discharge control strategy of substation DC system based on the principle of grid-connected inverter technology,cooperative communication technology and information technology. The control strategy proposed in this paper changes the method of manually using the resistance box,realizing the remote control of charging and discharging and online real-time monitoring. The strategy meets the requirements of intelligence and information,and provides a powerful guarantee for promoting remote charging and discharging technology.
