在电气化铁道牵引变电站中 ,装设无功补偿电容器和谐波滤波器是提高功率因数、改善电能质量的重要手段。为保证电容器组和滤波器组的安全、有效、协调运行 ,我们研制了一种变电站无功补偿和滤波器微机监控装置 ,本文介绍该装置的工作原理及硬件设计方法
In the electrified railway traction substation, the installation of reactive power compensation capacitors and harmonic filters is to improve the power factor, an important means to improve power quality. In order to ensure the safe, effective and coordinated operation of capacitor bank and filter bank, we have developed a substation reactive power compensation and filter microcomputer monitoring device. This article describes the working principle of the device and the hardware design method
