放水路

A detailed mathematical model for water head was constructed, which can describe relations among water volume, water discharge, water spillage, forebay elevation and tailrace elevation.

构建了描述蓄水量、发电引用流量、弃水流量、水库前池水位和放水路水位之间关系的水电站水头特性详细数学模型。

The detailed representation of cascade hydro plants, which includes water volume, water inflow, water discharge, forebay elevation, tailrace elevation and effective water head, is studied in the proposed strategy. The uncertainties, such as water inflows, electricity prices and unit status are taken into account as well.

模型全面分析了蓄水量、弃水量、前池水位、放水路水位、发电水头之间的关系，并考虑了电价、入库径流量、机组运行状况等不确定因素对梯级水电站短期优化调度问题的影响。

2 Should ensure that the cooling pond, cleaning, there must be no debris, dirt, every six months to carry out a sea of washing machines, water pipes, to remove scale, it would be specific about 25 kg of hydrochloric acid into the plastic bucket, then on the pump inlet and outlet pipe in plastic buckets together Add to the closure of machine power, a separate 15-minute run to open pumps, hydrochloric acid in the sea in circulation, remove furring.

3.2 应确保冷却水池内清洁，不得有杂物、污垢，每六个月要对机器水路进行一次清洗，除去水管内水垢，具体做法是将25kg左右的盐酸倒入塑料桶中，然后将水泵上的进水管和出水管一并放入塑料桶中，关闭机器电源，单独开启水泵运行15分钟，使盐酸在水路中循环流动，可以除去水垢。
