综合利用小水库群简易优化调度

A Simplified Optimal Operation Model for Comprehensive Utilization Multiple Reservoir System

提出一种以弃水量最小为目标函数的水库群简易优化调度方法──动态空库系数法。任一时刻某水库的空库系数反映该水库在该时刻的蓄水能力和供水能力。本法用时段初各水库空库系数的大小决定水库群的蓄放水次序，在满足约束条件下，时段末保持各水库的空库系数相等，由此尽可能地拦蓄径流，使弃水量最小。

A simplified optimal operation model for multiple reservoir system, dynamic emptying storage coefficient method, is introduced by least surplus water in this paper. The emptying storage coefficient of a reservoir at any time indicates the ability of water storage and supply of the reservoir at that time. Based on this method, the storage and draft orders of a multi-reservoir system are determined by the factors of every reservoir of the system in the initial of a time interval, and the emptying storage coefficients of every reservoir are kept equal at the end of the interval under constraints. In this way, the runoff can be retained in reservoirs as much as possible and waste water will be minimized. The model is simple and easy, and can be used for small multiple reservoir system with multi-purpose.
