    • A turbomachinery driving apparatus using a dual inverter system and a method of controlling the same, wherein a main control unit for controlling the two inverters is omitted, and an external communication unit for transmitting signals representative of the mutual operational conditions of the inverters is made unnecessary, the exchanging of these signals being done simply, whereby the size, weight, manufacturing cost and the number of parts of the apparatus are reduced. First and second earth leakage breakers (ELB1, ELB2), inverters (INV1, INV2), pumps (4-1, 4-2) and motors (5-1, 5-2) constitute a full duplex feed water system. The inverters (INV1, INV2) are connected to each other by signal lines (S3) and adapted to exchange signals representative of their respective operational conditions and failure conditions and requirements for the operations of the partner systems. Out of the load condition detecting sensors, respective flow rate signal transmitting signal lines (S4, S5) are connected to the inverters directly, and pressure signal transmitting signal lines (S6, S7) in common.
    • 使用双逆变器系统的涡轮机械驱动装置及其控制方法,其中省略了用于控制两个逆变器的主控制单元,并且不需要用于发送代表逆变器的相互操作条件的信号的外部通信单元 这些信号的交换简单地进行,从而减小了装置的尺寸,重量,制造成本和部件数量。 第一和第二漏电断路器(ELB1,ELB2),逆变器(INV1,INV2),泵(4-1,4-2)和电动机(5-1,5-2)构成全双工给水系统。 逆变器(INV1,INV2)通过信号线(S3)彼此连接,并且适于交换表示其各自操作条件的信号和故障条件以及对方系统的操作的要求。 在负载条件检测传感器中,相应的流量信号发送信号线(S4,S5)直接连接到逆变器,压力信号发送信号线(S6,S7)共同连接。
