摘要
为及时排查变电站直流系统的安全隐患,需要定期对其运行状态进行全面准确的评价。基于直流系统的主要组成部分蓄电池组和直流屏,提出一种基于扣分制和熵值法的综合评价方法。通过扣分制评价蓄电池组和直流屏的设备状况,再通过熵值法评价蓄电池组和直流屏的电气性能。通过直流系统对各种问题的客观评价,避免了主观性和模糊性导致的偏差,提高了规范化和可靠性,为变电站直流系统的运行维护的标准化提供参考。
In order to find out the hidden danger of substation DC system in time, it is necessary to make a comprehensive and accurate evaluation of its operation status. According to the battery set and DC screen, which is the key component in DC system, a comprehensive evaluation method based on mark-deducting system and entropy method is put forward. The device status of the battelle set and DC screen is evaluated by the mark-deducting system, and the electrical performance of the battery set and DC screen is evaluated by the entropy method. Through the objective evaluation of various problems in the DC system, the deviation caused by subjectivity and fuzzification is avoided, and the standardization and reliability is improved.
