摘 要: | 针对河北张河湾蓄能发电有限责任公司1号机组由抽水工况转抽水调相工况过程中出现的停机问题,从差动保护动作的原理和工况信号两方面进行分析,认为工况转换时送给保护的工况信号叠加是造成保护误动停机的原因,并提出优化机组工况代码的解决措施.

关 键 词: | 抽水蓄能机组 保护动作 工况代码 信号叠加 |
Optimizing of Unit Operating Mode Code of Pumped Storage Unit |

Abstract: | Based on the mode change failure of Hebei Zhang-hewan Storage Power Co.Ltd No.1 unit,this paper analyses the principle of current differential protection and the mistake of unit mode code.It gives the result that protection system getting a wrong mode code by superposition of signals causes this mode change failure.This paper also give an optimizing unit mode code solution for this kind of problem. |

Keywords: | pumped storage power unit protection action operating mode code superposition of signals |
