Low Voltage Reactive Power Dynamic Filtration Reactive Compensation Device
Application
It is widely use in the distribution system of power industry, metallurgy, railway, military, petroleum, machinery, chemical industry, light industry, building material, mineral, shipbuilding and etc, where both dynamic reactive compensation and harmonic filtration are required
General
While technology developing, plenty of electronic and power equipment are put into use, so the conflict between dynamic reactive compensation (fast tracking reactive compensation) and harmonic treatment is more and more obvious, ZM-DDL series intelligent dynamic reactive compensation equipment adopted the advanced power and electronic technology, information technology, intelligent control technology, to solve the interference of harmonic waves to the switching of shunt capacitors, also eliminate the harmonics according to the actual requirement, purify the power network, as a new generation of smart type dynamic reactive compensation and harmonic filtration complete set equipment.
Function
Effectively support system voltage, ensure the system run in normal state and keep high power factor, avoid penalty, also improve the using rate of equipment
Effectively restrict harmonics
Lessen loss and save energy
Model and implication
Main technical data
Technical Features
Large-scaled transistor current through-zero switching technology, can switch on/off capacitors at zero current, no surge, no impulse,
Fast tracking the change of load in the system, correspond dynamically to switching on/off at real time, response time <20mS
Assembled with smart detection terminal, combine the dynamic reactive compensation device with automatic system of the distribution network, realize the control of instantaneous switching, the local monitor of the related electricity quality, parameters, and remote operations as remote measurement, remote communication, remote control, meanwhile over-current, over-voltage, under-voltage, three-phase imbalance, temperature protections provided.
Principle Description
Standard tuning type:
It is mainly used in the system where has a little harmonics and the load change very quickly. Generally, the simple reactive compensation device can't be used for such system, because it has three problems: firstly shunt capacitors will amplify the harmonics, capacitor bank and system will form parallel resonance, make harmonic current to be enlarged, further the distortion of voltage and current will be more severe; Secondly the direct influence on shunt capacitors, harmonic current superimposed on basic wave, effective current rise up and lead to high temperature rise, this will shorten the service life of capacitors; thirdly it is difficult to track the quickly changed load, easy to over compensation or under compensation, then system voltage fluctuation happen. Regarding these problems, for the system with harmonic contents less than 30%, reactive compensation device shall be directly series connected with tuning reactor, make the resonance freq of this loop less than lowest power of harmonic wave, and make the current as capacitive value at power frequency namely improving power factor, and make current as inductive value at resonance freq, namely preventing resonance and amplification. Our tuning type standard ZM-DDL dynamic reactive compensation device can absorb more than 40% of 5th, 7th powers of harmonic waves
