压缩机控制装置、压缩机系统及压缩机控制方法
摘要：
该压缩机控制装置对压缩机的流量进行控制，该压缩机具有相对出口侧流路并列连接的多个叶轮和调整各叶轮的流量的流量调整部，该压缩机控制装置具备：检测出口侧流路的压力的压力检测部；检测各叶轮的流量的流量检测部；基于压力检测部的检测结果向流量调整部输出每个叶轮的流量调整指令来进行控制的控制部，控制部对作为流量的下限目标值而设定的设定点与各叶轮的流量进行比较，基于比较结果对其他叶轮的流量调整指令进行修正。
摘要（英）：

Provided is a compressor control device configured to control a flow rate of a compressor having a plurality of impellers connected to an outlet port-side flow path in parallel and a flow rate regulation unit configured to regulate a flow rate of each of the impellers, the compressor control device including a pressure detection unit configured to detect a pressure of the outlet port-side flow path, a flow rate detection unit configured to detect the flow rate of each of the impellers, and a control unit configured to output a flow rate regulation command of each of the impellers to the flow rate regulation unit and control the flow rate regulation unit based on the detection result of the pressure detection unit.
