变电站站用不停电改造技术
|
摘要
常规交直流系统改造时,若停用任一台站用变,尤其是对双电源系统的重要负荷的站内用电,可靠性都将大幅下降。针对变电站站内交直流电源系统改造期间的站内设备停电问题,根据站内电源和负荷特点,提出新型站用电停电改造方案。通过构建负荷转移平台,满足站内电源改造时站内负荷短时停电或不停电的需求。同时,通过该平台无线数据采集器的电源监视和报警功能,保障平台运行和维护的可靠性。
In the transformation of conventional AC/DC systems,if any substation is stopped,the reliability of the substation power consumption,especially for the important load of the dual power supply system,will be greatly reduced.Aiming at the short-term or long-term power outage of equipment in substation during the transformation of AC/DC power supply system,according to the characteristics of power supply and load in substation,a new power outage transformation scheme for substation is put forward. By constructing a load transfer platform,the short-term power outage or non-outage of load in substation during the transformation of power supply in substation can be satisfied.At the same time,the reliability of operation and maintenance of the platform can be guaranteed through the power monitoring and alarm function of wireless data acquisition on the platform.
