配电网供电可靠性水平提升的探讨

供电可靠性是衡量对用户连续供电水平的重要指标，它由设备质量、供电安全准则、运行维护水平来保证。设备质量是影响供电可靠性的一个重要因素，存在一个从微观到宏观，从单元设备到系统构成的局部认识和整体认识问题。对设备质量的认识不足，会形成一些短期行为，造成设备寿命周期短、设备功能欠缺、设备更新过快、过于盲目等，以致造成投资的不必要浪费和可靠性水平不能得到有效提升。

Discussion on the reliability improvement of distribution network

The reliability of the power supply is an important indicator to measure the level of power supply continuity for user, which be assured by the quality of equipment, the stands of electricity supply security and the level of operating maintenance. The quality of equipment is an important factor that can influence the reliability of the power supply, which have a partially and totally understand problem from the micro （ the equipment unit） and macro （ the system）. Due to insufficient knowledge of the quality of equipment, some short - term actions will be formed, causing the short cycle of equipment, the devoid of equipment function, update too fast, too blind and so on, resulting in unnecessary waste of the investment and fail to improve the level of reliability.
