Constant water level controller
专利汇可以提供Constant water level controller专利检索，专利查询，专利分析的服务。并且PURPOSE:The relieve the load of a dam supervisor, to prevent discharge in error by manual operation and to improve the reliability of constant water level control by providing a discharge control means even if the dam storage water level exceeds the upper limit of the constant water level control water level region. CONSTITUTION:A constant water level controller 7 has a flow calculation section 74, a discharge amount calculating section 75, and a discharge amount control section 76 and if the dam storage water level exceeds the upper limit of the constant water level control water level region, the storage water level is adjusted within the constant water level control region by controlling the discharge amount. That is, a dam water level H signal indicates the start of constant water level control in the flow where the setting water level of the upper limit of the constant water level control water level region is exceeded, a calculation section 75 calculates a gate discharge amount Q0 and a calculation section 74 calculates a flow Qi. Further, a control section 76 gives the discharge amount Q0 command to a gate discharge control section 73, from which a gate opening P command is given to a gate driver 5. Thus, the dam water level is adjusted within the control range, the load of the supervisor is retrieved, discharge in error is prevented and the reliability of the constant water level is improved.，下面是Constant water level controller专利的具体信息内容。
