    • Disclosed is a power conversion device, wherein among the optical fiber cables used in control/communication, at least the majority of high-voltage optical fiber cables with a dielectric strength against the output voltages of a plurality of cells can be eliminated and thus a low-voltage optical fiber cable with a dielectric strength against the output voltage of one cell can be used. Furthermore, here, the length required for the optical fiber cable can be reduced. A controller of the power conversion device comprising a plurality of cascade-connected cells comprises a central controller, and a cell controller with the same potential as each cell, the cell controller being installed in the vicinity of each cell, wherein the central controller and each cell controller are daisy-chained using an optical fiber cable.

    • In a system to which a fluctuating load is connected, compensating for fluctuation in voltage harmonics at the load connecting point and fluctuation in system current harmonics has been difficult for a power converting device connected in parallel with the load. To resolve the problem, a power converting device connected in parallel with a fluctuating load includes: a Fourier series expansion unit which executes Fourier series expansion to load current by use of a reference sine wave in sync with a system and thereby outputs Fourier coefficients; and a fundamental component calculating unit which calculates a positive phase active fundamental component of the load current from the Fourier coefficients. A current instruction of the power converting device is generated by subtracting the fundamental current from the load current. With the current instruction, the fluctuations in system current harmonics and in voltage harmonics at the connecting point can be compensated for.
    • 在连接波动负载的系统中,与负载并联连接的电力转换装置难以补偿负载连接点的电压谐波的波动和系统电流谐波的波动。 为了解决该问题,与波动负载并联连接的电力转换装置包括:傅立叶级数扩展单元,其通过使用与系统同步的参考正弦波来执行傅里叶级数展开以加载电流,从而输出傅立叶系数; 以及从傅立叶系数计算负载电流的正相位有源基波分量的基波分量计算单元。 通过从负载电流中减去基波电流来产生电力转换装置的电流指令。 利用当前的指令,可以补偿系统电流谐波和连接点电压谐波的波动。
