Embodiment Construction

[0025] A reservoir scheduling risk identification method, comprising the following steps:

[0026] Step 1, basic data preparation, basic data include: risk classification identification table, generalized length of river section.

[0027] Collect data, determine the risk description, risk time, risk distribution location (the river section where the risk may occur), and form Table 1.

[0028] The risk description includes: the reason for the risk and the measures to be taken.

[0029] Risk time: According to the actual situation, it can be classified by month or ten days, and the time interval is determined according to the actual situation.

[0030] Risk categories include: shipping, ecology, power generation, flood control, sediment, society, water storage, ecology / emergency / water replenishment, and others.

Abstract

A reservoir scheduling risk identification method comprises: preparing basic patterns and materials, determining risk description, risk time and a probable risk river section, and forming a table; determining the probable risk river section, and according to the length of the river section, estimating a proportion; drawing a plurality of concentric circles, and dividing the concentric circles into multiple parts; converting the generated concentric circles into a polygon; according a time calendar, combining elements in arcgis; adding a comment field in the generated polygon, and adding risk description; marking a river section control point; according to risk types, classifying generated risk maps, assigning different colors for different types; and adding legends to finish risk map creation, and identifying a reservoir scheduling risk by using the risk maps. According to the reservoir scheduling risk identification method provided by the invention, time and space elements are rapidly displayed by using a pie chart, thereby guiding the reservoir scheduling risk identification and improving the working efficiency of reservoir scheduling.

Description

technical field [0001] The invention relates to a method for identifying key factors in the field of water conservancy and hydropower, in particular to a method for identifying risks in reservoir dispatching. Background technique [0002] The reservoir operation risk has a one-to-one relationship with the reservoir operation target for each period of a hydrological year. For large mainstream reservoirs, it is necessary to solve various contradictions in flood control, shipping, power generation, sediment, ecology, and drought resistance for different river sections in different periods. With the development of the national economy, from the local to the central, the social and economic benefits of reservoir regulation are gradually paid attention to. The risk of reservoir dispatching becomes increasingly prominent when the eye-catching dispatching is met. A simple, unambiguous way of reflecting this risk in relation to time and space is needed. In order to quickly identif...
