Second-level runoff adjustment and scheduling map drawing method of reservoir mainly used for urban and rural water supply and irrigation

Abstract

The invention discloses a second-level runoff adjustment and scheduling map form of a reservoir mainly used for urban and rural water supply and irrigation, a drawing method of the graph and a method for calculating second-level runoff adjustment of the reservoir by using the scheduling map. The scheduling map comprises a flood control region, a water supply increase region, a region for guaranteeing water for urban and rural water supply and irrigation, a region for guaranteeing water for urban and rural water supply and reducing water for irrigation and a region for reducing water for urban and rural water supply and irrigation, and the regions are partitioned according to a flood control limit line R and reservoir scheduling lines r1, r2 and r3. According to the second-level runoff adjustment and scheduling map drawing method of reservoir mainly used for urban and rural water supply and irrigation, the second-level runoff adjustment and scheduling map form of the reservoir mainly used for urban and rural water supply and irrigation is provided at the first time; the reservoir region is partitioned on the scheduling map into 5 operating regions such as the flood control region, the water supply increase region, the region for guaranteeing water for urban and rural water supply and irrigation, the region for guaranteeing water for urban and rural water supply and reducing water for irrigation and the region for reducing water for urban and rural water supply and irrigation; the 5 operating regions are partitioned according to 3 reservoir scheduling lines r1, r2 and r3 and the flood control limit line; and the urban and rural water supply amount and the irrigation water amount of the reservoir in each region in the reservoir scheduling map are prepared.

Description

technical field [0001] The present invention relates to the form and drawing method of reservoir secondary runoff regulation and reservoir dispatching diagram, specifically refers to a kind of reservoir secondary runoff regulation dispatching diagram form and its drawing method based on urban and rural water supply and irrigation and the use of dispatching diagram to control the reservoir The method by which secondary runoff regulation is calculated. Background technique [0002] 1) Technology Status [0003] my country has always attached great importance to urban and rural water supply and agricultural irrigation, and has built a large number of reservoirs focusing on urban and rural water supply and irrigation. In the engineering design and reservoir operation management of the reservoirs, what is the reservoir scheduling diagram like? The form and how to draw it, how to calculate the reservoir runoff regulation, and so far there is no perfect reservoir regulation diagram...

Problems solved by technology

[0005] 2) Difficulties in technical research

This method is still feasible in the planning stage, but it is difficult to apply in the actual operation and scheduling of the reservoir, because in the actual operation and scheduling of the reservoir, it is impossible to determine in advance the annual runoff of the reservoir, whether to reduce it and how to reduce irrigation water consumption
