Abstract

The invention discloses a reservoir flood season operation water level dynamic control method and system based on a typhoon path, and the method comprises the steps: predicting the path length of a typhoon center and a reservoir through calculating the typhoon path, and predicting the time for the typhoon center to reach the reservoir according to the path length and the typhoon operation speed; according to the relation between the typhoon distance and the rainfall intensity, the pre-drainage time duration of the reservoir is predicted; solving the maximum operating water level of the reservoir, and dynamically determining the maximum operating water level of the reservoir according to the predicted period length and the pre-discharge capacity; and finally, dynamically controlling the water level of the reservoir according to the dynamically determined highest operating water level of the reservoir. According to the method, typhoon information is considered, the prediction period of dynamic control of the running water level in the flood season is prolonged, the calculation result is closer to the actual reservoir dispatching, and the reservoir flood resources are utilized to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of reservoir dispatching, and relates to a method and system for dynamic control of the water level in the flood season of the reservoir, and in particular to a dispatching operation problem for coastal typhoon-based reservoirs, estimating the length of the rainstorm forecast period based on the typhoon path, and then developing the reservoir Method and system for dynamic control of operating water level in flood season. Background technique [0002] The implementation of dynamic control of the water level of the reservoir during the flood season can tap the power generation benefits of the reservoir and improve the comprehensive benefits of the reservoir without increasing the risk of flood control. At present, the dynamic control of the operating water level of the reservoir group in the flood season still uses a single inflow runoff forecast as the main input information, lacking the ability to further an...
