近年来,随着采油厂的四化建设的不断推进,油井控制设备对电压质量的要求也越来越高。因电压瞬时暂降造成油井大面积停井的故障频繁发生,影响油井开采的连续性,严重时造成油井杆卡,影响输油油水流度比,停井的时间不长,但需要较长时间来... 近年来,随着采油厂的四化建设的不断推进,油井控制设备对电压质量的要求也越来越高。因电压瞬时暂降造成油井大面积停井的故障频繁发生,影响油井开采的连续性,严重时造成油井杆卡,影响输油油水流度比,停井的时间不长,但需要较长时间来恢复油井产能。通过现场调研分析,油井四化设备和变频器控制器自带保护与线路保护定值缺少配合,未能躲过电压暂降周期,从而造成油井停井。针对这一问题,通过优化电网运行方式,提高电网运行可靠性,优化油井设备保护定值,来降低电压暂降对油井运行的影响。 展开更多

The paper presents the methods proposed by the authors to be applied in operation of substations. The substations taken in consideration were rehabilitated by replacing the existing equipments by new equipments, the last generation. The methods consist in study of equipment's failures, study of equipment's behaviour, study of substation architecture and study of systems operation. Paper presents new equipments on their architecture and performances. The parts of method exposed in this paper are based on the operational reliability. The mathematical methods and new analyses methods are given for resolving the issues on operation of substations. The results of this study will be used to obtain the best solution for operation of the substations. The results of the analysis were applied to some substation from the Transmission Power Grid. 展开更多
