摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for controlling a private power generation plant, which suppress an operation cost rise when balancing a steam load by operation of an atmospheric discharge valve of a private power generation plant. SOLUTION: A plant state quantity of the private power generation plant is read in (F101) and a differential deducting a process steam flow rate variation from a main steam flow rate variation is then calculated (F102). It is judged whether the differential is a negative value or a positive value exceeding a threshold value (F103, F107). When the differential is the negative value, a closing operation amount of the atmospheric discharge valve is calculated (F104) and the atmospheric discharge valve is controlled by the closing operation amount. When the differential is the positive value exceeding the threshold value, an opening operation amount of the atmospheric discharge valve is calculated (F108) and an operation cost when the opening operation amount is used is calculated (F109). A differential between the operation cost and an operation cost in an existing state is calculated (F110), it is judged whether or not the differential exceeds a certain threshold value (F111), and if not exceed, the atmospheric discharge valve is controlled for opening by the calculated opening operation amount.

摘要翻译：要解决的问题：提供一种用于控制私人发电厂的方法和装置，其通过私人发电厂的大气排放阀的操作来平衡蒸汽负载时抑制运行成本上升。解决方案：读取私人发电厂的工厂状态量（F101），然后计算从主蒸汽流量变化量减去过程蒸汽流量变化的差值（F102）。判断差分是负值还是正值超过阈值（F103，F107）。当差值为负值时，计算出大气排放阀的关闭操作量（F104），通过关闭操作量来控制大气排放阀。当差分值为正值超过阈值时，计算大气排放阀的打开操作量（F108），并计算使用打开操作量时的操作成本（F109）。计算现有状态下的操作成本与操作成本之间的差值（F110），判断差分是否超过某一阈值（F111），如果不超过，则控制大气排出阀打开通过计算的打开操作量。版权所有（C）2006，JPO＆NCIPI
