    • PURPOSE:To enable to supply a voltage to a system having a power source different in frequency in high speed respose by providing the first rotary frequency converter and the second DC stationary type frequency converter between two systems. CONSTITUTION:A power source 10 is provided at the back of a bus 1, no power source is provided at the back of a bus 34, but a variable load 6 is provided at the back of the bus 34. The buses 1, 34 are connected by a rotary frequency converter having a motor 2, a drive shaft 3 and a generator 4. The buses 1, 34 are connected therebetween via stationary DC frequency converter composed of the converters 32, 33 operated as power reactor and inverter and a DC reactor 31.
    • 目的:通过在两个系统之间提供第一个旋转频率转换器和第二个直流静止型变频器,能够高速复位具有频率不同的电源的系统。 构成:在总线1的背面设置有电源10,在总线34的背面没有电源,而在总线34的背面设有可变负载6.总线1,34是 通过具有电动机2,驱动轴3和发电机4的旋转变频器连接。总线1,34通过由作为动力电抗器和逆变器操作的转换器32,33构成的固定DC变频器和直流电抗器 31。
