SCR low pressure TSC dynamic reactive power compensation device technical parameters: ◆ standard: GB / T 15576-1995 static reactive power compensation device overall technical condition Q / HWH001-2008 "TSC dynamic reactive power compensation device Technical Specifications" ◆ Dynamic Response time: <20ms ◆ compensation capacity: (kvar): 90-810 (single set of capacity) Heilongjiang harmonic control, you can use multiple sets and switching ◆ series: 2-11 grade ◆ Cabinet protection grade: IP30 ◆ Environment Temperature: -30 ゜ C - + 50 ゜ C APF basic principle of active power filter harmonic control, is the use of modern electronic technology and new power harmonics made based on the high-speed DSP digital signal processing devices Governance special equipment. It is composed of two major parts of the circuit generated by the command current computing circuit and compensation current. Command current computing circuit current in the line real-time monitoring, and analog current signals into digital signals into high-speed digital signal processor (DSP) for signal processing, the harmonics of the fundamental separation and pulse width modulation ( PWM) signal in the form of compensation current circuit occurs to send the drive pulse frequency furnace harmonic control, drive IGBT or IPM power modules generate harmonic currents with equal amplitude, polarity opposite compensation current into the power grid, the harmonic currents compensation or offset, the initiative to eliminate power harmonics.
