The invention discloses a
water level prediction analysis and control method of a
hydropower station reservoir, comprising the following steps: 1) acquiring real-time operation information of a
cascade hydropower station group; 2) calculating the change amount of the
water storage flow in the reservoir; 3) analyzing and predicting that trend of the
reservoir water level, and drawing a water levelchange trend map; 4) calculating the suggested open degree of the gate adjustment, and automatically adjusting the opening degree of the gate; 5) when the gate adjustment needs to increase the
discharge, automatically communicating the automatic linkage flood release
warning system to send the flood release warning information to the person in charge of the downstream
flood control in a timely manner. The invention can accurately predict the short-term change trend of the
water level of the reservoir of the
hydropower station, and further adjust the gate so as to reduce the operation frequencyof the gate, improve the gate adjustment precision and realize the purpose of maximizing the utilization of
water resources for generating
electricity. At the same time, when the
discharge of the gate is increased, the flood release warning information can be transmitted in time through communication with the flood release
warning system, so as to ensure the safety of the life and property of people in the downstream.
