自动低频减负荷装置定值整定探讨

Discussion on Setting for Automatic Under-frequency Load-shedding Device

自动低频减负荷装置是保证电网安全稳定运行的重要安全自动装置,属于电网三道安全防线中的最后一道防线。为有效发挥自动低频减负荷装置的重要作用,应正确进行装置定值的整定。分析了当前自动低频减负荷装置定值整定中存在的主要问题,提出了进行正确整定的方法。

Automatic under-frequency load-shedding device is an important security automation device for insuring power grid operation in safety and stably, it is the last line of the three defensive lines for power grid. For exerting the functions of the automatic under-frequency load-shedding device, setting for the device should be calculated correctly. The main problems existed in the setting calculation are analyzed, and the correct method of the setting calculation is put forward.
