Improved algorithm of water energy utilization improvement rate and cascade hydropower station dispatching benefit evaluation system

Abstract

The present invention relates to an improved algorithm of water energy utilization improvement rate and cascade hydropower station dispatching benefit evaluation system, comprising the following steps: according to the monthly average water level of the actual operation of the reservoir in the past ten years, the dead water level of the reservoir design, the normal high water level of the reservoir design, and the reservoir dispatching diagram Data, calculate the monthly assessment index of the reservoir water level control coefficient, and inversely find the water level control target; calculate the actual power generation; calculate the assessment power generation according to the initial water level, interval flow, water level control target, and dispatching rules of the actual operating water level control coefficient of the reservoir; calculate the storage capacity Differential power; calculate the improvement rate of water energy utilization based on actual power generation, assessment power generation, and storage capacity difference power. The invention can improve the stability and adaptability of the electricity calculation results of the cascade hydropower station group assessment, and can avoid the situation that the water level will drop to the stagnant water level when the inflow of water is less at the beginning of the year, according to the dispatching chart. to good guidance.

Description

technical field [0001] The invention relates to an improved algorithm for increasing the utilization rate of water energy and a dispatching benefit evaluation system for cascade hydropower stations, and belongs to the technical field of optimal dispatching of cascade hydropower station groups in a river basin. Background technique [0002] The improvement rate of water energy utilization is an important index to measure the effectiveness of optimal dispatching of hydropower stations. The assessment of the improvement rate of water energy utilization is of great significance for promoting water regulation work and making full use of water energy resources. The improvement rate of water energy utilization is the ratio of the water-saving and increased power generation of hydropower stations to the assessed power. The assessment electricity is calculated according to the actual water flow in the statistical period and according to the design standards of the hydropower station;...

Problems solved by technology

On the one hand, the dispatching chart only depends on the current water level when used, but in the actual dispatching process, the formulation of the dispatching strategy should not only consider the current water level situation, but also the future water inflow situation, and the upper and lower basic dispatching lines of the dispatching map The range in the middle is relatively large, and it is not reasonable enough to calculate the assessment power based on the scheduling chart
