In recent years

with the rapid increase of the number and installed capacity of hydropower stations in Sichuan

the impact of simultaneous shutdown and peak averting measures of the centralized large-scale hydropower generator group on the safe operation of power grid has become increasingly prominent. Combined with the actual situation of hydropower station operation

hydropower dispatching management and power grid operation in Sichuan

it is defined that the main factors causing shutdown and peak averting in hydropower station are flow

sediment and impurities

and the impact of shutdown and peak averting of the centralized largescale run-of-river hydropower stations on power grid dispatching is analyzed. The distribution characteristics of shutdown and peak averting is studied from two dimensions of time and space (watershed)

and the flow and water quality are proposed as a feasible judgment method to predict whether the hydropower station will shut down and avoid peak load. Finally

the design idea for shutdown and peak averting management system of the centralized large-scale hydropower generator group is introduced from the aspects of prediction method

real-time monitoring and system architecture. The practical application of the management system in Sichuan power grid shows that the proposed system can improve the organization ability of power grid dispatching to control the real-time shutdown and peak averting

help to assist the safe and stable operation of power grid in flood season

and provide a reference for the shutdown and peak averting management of the regional power grid and hydropower plants.
