Method for dispatching flood gate of transformer substation

Abstract

The invention discloses a method for dispatching a flood gate of a transformer substation, and belongs to the field of electric power engineering and flood control project. The method includes the following steps that a coupling model of a rainfall runoff model, a one-dimensional hydrodynamic model and a two-dimensional hydrodynamic model of an area where the transformer substation is located is established; rainfall forecast data within the preset time are obtained, a time series file is made and input into the rainfall runoff model, the rainfall runoff model serves as the boundary conditionof the one-dimensional hydrodynamic model, and the coupling model operates to obtain a forecast result of the one-dimensional hydrodynamic model for the water level of a flood diversion gate and a forecast result of the two-dimensional hydrodynamic model for the highest flood discharge water level in the transformer substation area; and the forecast results are analyzed, and it is judged that whether the flood gate of the transformer substation needs to be closed or not. According to the method, the possibility of flood occurring in the area where the transformer substation is located is estimated in advance, thus it is ensured that the flood gate of the transformer substation has sufficient time to be closed, and the loss caused by untimely closure of the flood gate is avoided.

Description

technical field [0001] The invention relates to a method for dispatching a substation flood control gate, which belongs to the field of electric power engineering flood control engineering. Background technique [0002] Restricted by the environment, more and more substation projects are currently located near rivers, lakes or even within flood discharge areas, which are directly affected by flooding. When the design elevation of the substation site in the flood discharge area cannot meet the design flood level corresponding to the corresponding flood control standard, flood control measures must be taken to ensure the safety of the project's flood control. The current flood control measures mainly adopt the method of setting a flood control wall under the fence and setting a flood control gate at the gate. [0003] At present, the dispatching mechanism of the flood control gate of the substation located in the flood discharge area is as follows: after the actual flood occur...

Problems solved by technology

However, the flood rises and falls steeply, and the confluence speed is fast. When the actual flood occurs, the closure of the flood control gate is often dispatched due to the short time and too little time to close the flood control gate, causing the flood to pour into the substation, causing devastating flood disasters.
