BRIEF INTRODUCTION SFR-APF active power filter is a new type of power quality improvement production for dynamically filtering harmonics and compensating As great amount of the nonlinear load was applied in the power system,the harmonic distortion accounts a big proportion of the grid. It increased the line loss of the power supply and interfered the running of the protection devices of the power substation and automation devices of the industrial control system. reactive power. It can filtering and compensate harmonic (variable in orders and frequency) and dynamic reactive power in real time....

The APF acquires the current signal of the load by the CT, separating the harmonic by the intelligent FFT(Fast Fourier Transform) by the DSP than send to the internal IGBT by the PWM signal. The APF will generate generate the compensation current with the same value but opposite phase as the system harmonic in order to achieve the real-time dynamic filtering function.

MAIN FEATURES SFR-APF is applied to realize dynamic tracking compensation and on-demand allocation of active filtering, reactive power compensation and unbalanced current compensation. EXCELLENT PROTECTION FOR EQUIPMENT AND SYSTEM Device internal fault protection Device external electrical fault protection Automatic derating if the working environment exceeds the limits FLEXIBLE APPLICATION SCHEME Support current limiting through software and hardware Modular design, easy to expand, up to 8 modules can be connected in parallel. Resonance avoidance Plug-in frame or wall-mounted installation,...
