摘要随着电网结构的逐步增强,为了降低日益增大的220kV电网短路电流水平,必须逐步采取开环运行方式。但在220kV和110kV局部电网结构尚不完善的情况下,解环运行往往难以实现。在此过渡时期可以采取弱开环方式,以天富热电电网为例,通过分析论证,得出在电网结构不完善的过渡时期,采用弱开环方式将优于完全开环方式的结论,这可为电网安全可靠运行提供一种新的方式。

Abstract：With the development of power grid structure is gradually increased, in order to reduce the increasing 220 kV power system short-circuit current level, must gradually adopt open loop operation mode. But in 220kV and 110kV local power grid structure is not perfect situation, hydrolysis of cyclic operation is often difficult to achieve. During this transitional period can take weak open-loop mode, the thermoelectric power grid for example, through the analysis, obtains in the grid structure is not perfect in the period of transition, the weak open-loop mode will be superior to completely open loop way conclusion, which can provide safe and reliable operation of power grids to provide a new way.

Key words： power system short circuit current open loop operation 220kV/110kV grid partition weak open-loop mode
