Power Quality Problems Residential community power grids are low-voltage power distribution networks, generally connected to large power grids by 10/0.4kV transformers. Most of the loads in the grid work at three-phase 480V and single-phase 220V voltage levels, mainly small-capacity loads, such as air conditioners, refrigerators, and televisions. Machines and other household appliances. Most house...
YTPQC-AHF Active Harmonic Filter YTPQC-AHF Active Harmonic Filter is a perfect and comprehensive solution to the power quality issues of power grid, such as harmonics, reactive power and 3 phase load unbalance. YTPQC-AHF which is in parallel to power grid can detect the harmonic wave in power grid in time, generate the reverse-phase compensation current through the converter and dynamica...
Power Factor PF Measurement The control unit calculates: The power factor per phase PFL1, PFL2, PFL3, from the phase active and apparent powers. The total power factor PF from the total active power Ptotal and the total apparent power Stotal: PF = Ptotal / Stotal NOTE: Stot is the vector or arithmetic total apparent power, depending on the setting. This indicator qualifies:...
Introduction To Capacitors And Reactors Reactance includes inductive reactance and capacitive reactance, and reactor includes inductive reactance (inductor) and capacitive reactance (capacitor). Inductance has the function of "blocking AC and blocking DC", that is, in the AC circuit, the characteristics of inductive reactance are used to "pass low-frequency DC and block high-frequency AC". The cap...

YTPQC-SVG/AHF Active Harmonic Filter and Static Var Generator Active Harmonic Filters(AHF) are new generation harmonic filters which use modern technologies and devices to provide revolutionary filtering solution.The Active filter is IGBT based harmonics generator. The active harmonic filter is connected in parallel to the load to be compensated. Static Var Generator(SVG) is IGBT (Integrated...
YTPQC-SVG Static Var Generator YTPQC-SVG (Static Var Generator / Compensator) detects load current through external current transformers (CT’s) on-line and analyzes reactive component of the load current by DSP controller, then control IGBT inverter to generate reactive current and compensates the load reactive current to meet the target of line power factor. The SVG compensates the reactive...
