Introduction of Functions

Harmonic Filter: HTQF is composed of command current computing circuit and compensation current generating circuit. Command current computing circuit conducts real-time monitoring of current in circuit; switch the analogue current signals into digital signals, and send the signals into DSP for handling; separate harmonics and fundamental wave, send drive pulse in form of PWM signals to compensation current generating circuit; drive IGBT power module, produce compensation current input network which has the same amplitude as harmonic amplitude and inverse polarity; compensate or balance out harmonic current, eliminate power harmonics actively, and thus realize the dynamic quick and complement treatment of power harmonics.

Dynamic reactive power compensation: While filtering harmonics, according to detected need for reactive power compensation, HTQF command current computing circuit can control internal capative and inductive fundamental current of compensation current generating circuit, conduct real-time compensation, set the target value of reactive power compensation through operation board. There are 4 working modes for choice, namely, “filter priority”, “reactive power priority”, “harmonic filter only”, “and reactive power compensation only”. The working mode should be selected according to specific conditions of power distribution system.

Correct unbalanced 3 phases: HTQF can compensate the unbalanced 3 phases respectively. It can conduct phase adjustment of active power through DC Energy Storage Systems shared by 3 phases, thus to correct unbalanced load of 3 phases. The operation of this function can also be set by operation board.

 

The advantages of Hoteam active power filter

1,The main components are all imported famous brands, such as:ABB circuit breaker,Schneider air breaker,German EPCOS DC capacitor,Fuji contactor,Germon Infineon IGBT,USA TI control(DSP)chip and so on, high quality components improved safety and reliability, guaranteed the quality of active power filter.

2,Adopt ripple cancellation converter patent technology(China patent:200910019887.8 ,201010180701,201010503315.X ), high current tracking speed,low ripple wave and power loss.

3,higher stable structure and advanced control method(China patent:201010275272.4 ),this make sure APF can be running steadily in a varity of complex sites.

4,multiple frequency 150MHz 32 bit high speed DSP (TMS320F2812) cooperative work, complete order current operation and system control function in real-time, high control precision,fast speed.

5,DC energy storage capacitor adopts multiple measures, from multi-angles of Brand select,working voltage,over voltage protection,electric buffer resistance,install position to guarantee safe operation and reliability, can effectively prevent from over voltage,over current and over temperature problems, the annual average working temperature of capacitor is under 30°C.

6,Perfect fault detection and protection system, including self-test after power on,alarm and protection of various faults or abnormal events,history event record function, furthest guarantee the safe and steady operation of equipment.

7,add transient voltage suppressor at input circuit, meet requirement of lightning protection.

8,fiber optics drive, safe,reliable,high anti-interference ability.

9,RS485 port, standard MODBUS communication protocol, computer remote control function.

10,can realize dynamice split phase reactive power compensation and three phase unbalance correction function.
