摘要
分析不同涌水量条件下,涌水充满水仓和用电峰谷的时间,提出半躲峰和完全躲峰的概念,以安全水仓水位控制为前提和以排水能耗最小为目标,实现煤矿井下排水系统的自动化.建立矿井水仓容量、涌水量、水泵运行台数与电价等相关参数间的数学模型,确定出自动排水系统的控制策略,给出多台水泵启、停台数运行的相应时段及时间,通过实例验证,该控制策略能减少5.1%的排水用电费用.
The time of full inflow into water storage and peak and valley time of electricity consumption were analyzed in the case of different water inflow.The concept of half escape peak and complete escape peak was advanced.Taking the safety control of water bunker level as premise and the drainage minimum energy consumption as objective,a mathematical model of correlative parameters such as about mine the sump capacity,water inflow,running number of water pump and electricity price etc was established to realize automation of drainage system under coal mine.The control strategy of automatic drainage system was determined and the number of pump sets running with multi-pump starting-stopping as well as their running time were given.It was verified by an actual example that with this control strategy,the power consumption cost for water drainage could be decreased by 5.1%.
