摘要
为寻求适合乌江梯级水库群最大发电效益的联合调度方式,对常用的梯级水库联合调度方式、模型建立进行了综合分析,提出以梯级蓄能调度图为指导,辅以水库蓄供水控制线为约束的联合调度方式,并给出了绘制梯级蓄能调度图的方法和步骤。实例分析结果表明,该方法不仅能合理控制水库蓄放水次序和蓄放水量,且调度条件简单,运行灵活,可有效增加梯级总发电效益,具有较好的实际应用前景。
In order to seek suitable joint operation scheme for Wujiang River cascade reservoirs, we analyze the commonly used joint operation scheme and the model establishment of cascade reservoirs comprehensively. It is proposed that the cascade pumped storage graph should be adopted as a guide, while supplemented by restriction of water storage and supply control line of reservoirs. The drawing method and process for cascade pumped storage graph is presented. The analysis of engineering example shows that this reservoir release order and water storage and release amount can be controlled by the method reasonably. The operation conditions of this method are simple and flexible, which can effectively increase total generation benefit of the cascade.
