煤矿供电防越级跳闸保护系统的应用研究
|
摘要
煤矿井下供电目前存在速断过流保护定值无法整定、漏电保护难实现比较等难题,导致漏电、短路等故障发生频繁,严重威胁供电可靠性。尤其广泛存在的“越级跳闸”问题,是影响煤矿井下可靠供电的一重要因素。鉴于此,结合实际工程提出一种煤矿供电防越级跳闸保护系统的应用方案,来彻底解决存在的“越级跳闸”问题,提高供电可靠性,实现“四遥”功能,为采区变无人值守创造条件。
本文结合常村矿井下实际情况,线路主保护采用数字式光纤差动保护,对其进行理论阐述及分析;简述防越级跳闸保护系统,介绍其主要构成部分及特色;阐述常村矿井下供电目前技术现状,针对越级跳闸进行原因分析,并给出应用方案。最后在现场对系统进行调试,验证可行性。
现场应用表明:系统运行稳定、设备功能齐全、可扩展性强、组网灵活、维护巡检方便,实现了保护的选择性和快速性,有效地避免了多次越级跳闸的发生,具有较高的使用价值和广阔的应用前景。
Mine existing quick-break power supply value can not be over-current protection setting, leakage protection and so difficult to achieve more difficult, leading to leakage, short circuit fault occurs frequently, a serious threat to reliability. In particular, widespread existence of "grade trip," the issue is the impact of a coal mine an important factor in reliable power supply. In view of this, combined with the actual project proposes a coal-powered anti-grade trip protection system applied research program, to solve the widespread problem of "grade trip" problem and improve power supply reliability and power supply system to achieve the "four remote" function, for the mining area to create conditions for unattended substation.
In this paper, the actual situation of the mine often the village, the main protection line of digital fiber optic differential protection, its theoretical explanation and analysis; brief anti-grade trip protection system, introduce the main components and characteristics; describes regular village for the mine Electric current technology situation, analyzes the reason for the grade trip, and give applications. Finally, the system debugging in the field to verify the feasibility.
Application shows that: the system is stable, the device functional and scalable, flexible networking, maintenance inspection easy to achieve the protection of the selectivity and fast, effectively prevent the occurrence of grade trip several times, with high use value and broad application prospects.
