摘要(Abstract)：
以某1 000 MW机组为例,分析了西门子T-3000 DEH系统甩负荷识别功能,尤其是KU(短甩)功能和LAW(长甩)功能的详细判断逻辑、KU触发后DEH系统的控制方式,对实际运行中可能出现的问题提出了优化建议。
Taking 1 000 MW units as an example, this paper introduces the load shedding recognition of Siemens T-3000 DEH system, especially the detailed judgment logic of KU(short shedding) and LAW(long shedding) as well as the control method of DEH system after KU is triggered. The paper gives optimization suggestions on problems which may occur in actual operation.
