北二35kV变电站相关二次设备运行可靠性分析
|
摘要
变电站二次设备运行可靠性能够很大程度上影响整个系统的稳定运行。当前,电力系统处于飞速发展时期,由于对经济性的考虑,有可能导致设备常处于过负荷运行性条件下。如果对应的二次系统不能做出正确动作,尤其线路随意跳闸的误动作,会使系统的故障影响范围扩大化,严重时会影响到大电网的稳定运行。本文以北二35kV变电站中的6kV改造柜为出发点,对变电站结构进行分析,重点分析变电站改造后二次设备对系统可靠性运行的技术研究和成果检验,对6kV改造柜稳定运行涉及到的可靠性理论、计算方法和运行策略进行研究,提出对应的可靠运行策略。
Secondary substation equipment operation reliability can significantly affect the stable operation of the entire system.At present, the power system is in a period of rapid development, because of economic considerations, it may lead to equipment often under overload operating conditions. If the corresponding two times system can not make the correct action, especially the line random tripping of the wrong action, will make the system fault impact range expanded, serious will affect the stable operation of the large power grid.In this paper, the 6 KV transformation cabinet in the 35 KV substation in the north is the starting point, and the structure of the substation is analyzed, and the technical research and results test of the reliability operation of the system after the transformation of the substation two times are analyzed emphatically.The reliability theory, calculation method and operation strategy involved in the stable operation of 6 KV retrofit cabinet are studied, and the corre sponding reliable operation strategy is put forward.
