Power quality problems

"To maintain the stability of power supply and keep the good power quality" is the basic principle how the power system operated. However, due to the mass consumption of non-linear loads recently and the conscientious requirements of the power quality for many precision equipments, how to minimize the bad quality power in the power supply chain is becoming a critical issue for power companies, related industries and research organizations.

There are 2 sources of power pollutions:

• When power system supplies electricity power, it will cause two types of physical phenomenal called "transient current" and "surge current". They make glitch on the sine current wave. Normally, the alternating current (AC)'s sine wave should be smooth. Therefore, the wasted power starts from here. This is power pollution.
  
  
• When the power transmits to the user end, the user end will generate a small electrical net. The old machines or motors cause a lot of "transient current" and "surge current" moved around in the small electrical net which wastes a lot of power and lower the power efficiency.

Furthermore, the problems regarding the power quality can be classified as followings.

• Transient, short time and long time low power pressure, or power interruption.
• Current wave mistakes. Such as harmonic current, Inter-harmonics, Line Voltage Notch
• Current unbalance
• Voltage flickers
• Frequency variations.
  

From the power system point of view, to keep the good power supply quality, the power company needs to maintain the stability and quality of the whole power system; the user needs to make sure the loading characteristics of consumption devices will not cause the power pollution to the power system.

From the electric equipment user's point of view, how to lower the utility waste; decrease the power interference between the equipments; and avoid the operational accidents by bad power quality when using the equipments are very crucial.

What is Power Factor?

Power factor is the percentage of electricity that's delivered to your location and used effectively, compared to what is wasted. For example, a 1.0 power factor means that all the electricity that's being delivered to your place is being used effectively for its purpose. However, most household, commercial or industrial users received less than 0. 9 power factor. This means that 90% or less of the electricity that is coming through your meter to your home or business is being used effectively, the other 10% or more is wasted by your inductive load. With a low power factor the utility has to deliver more electricity to do the same work, which means user has to pay more to get the equal electricity at power factor 1.0 they supposed to receive if they have low power factor electricity supply.

Why Improve Power Factor?

• The electricity bill will be smaller. Low power factor requires an increase in the electric utility's transmission and distribution capacity in order to handle the reactive power component caused by inductive loads. Electricity usually charge large customers with power factors less than 0.95 an additional fee. Increasing the power factor can avoid this additional fee.
• The internal electrical system's capacity will increase. Uncorrected power factor will cause increase losses in the electrical distribution system and limit capacity for expansion.
• Voltage drop at the point of use will be reduced (i.e. improved). Voltages below equipment rating will cause reduced efficiency, increase current, and reduced starting torque in motors. Under-voltage reduces the load motors can carry without overheating or stalling. Under-voltage also reduce output from lighting and resistance heating equipment.

Our Technology - to eliminate the power polluation, improve the power facor and keep good electricity quality.

The dynamometer ( reactor wave filter) is based on the theory of Micro-magnetism and the technology of Electromagnetic balance to adjust the incoming power to reach the Three-phase balance; as well as provide the proper power ratio to the power consuming equipments. In the mean time, by using the new high-tech material (Solid State Mica), the dynamometer can decrease the useless power ratio and multi-times harmonics, and eliminate the exciting currents; then series connects to the circuit of the master switch on meter. It will help all the power consumption equipments to work in a more actual power ratio environment, operate in a better power quality status and best of it, to save more power utility and customer's money.

Theory

We use the advanced technology of three-phase circuit corresponding combination to create the reactance filtering power saving effects. As shown on Figure 1, the internal electricity structure is to fix the combination of the series-connected reactor and the parallel-connected odd-even fixed circuits to a three-column core. In which core there's a filter to pass the higher harmonic voltage from the power transmission circuits. (mainly the third, fifth, seventh harmonic voltiage)

<Figure 1>

As shown on Figure 2, according to the power structure chart , when the input power goes to R-S-T end, the voltage immediately goes to the coil sets, then output voltage from the series coils and parallel coils. The magnetic coil flux in the serial coil is the magnetic flux generated by every exciting magnetic coil. Those flux will gather together on a three-column core to make the magnetic potential on the three-column core reached balance. Meanwhile, the quantity of magnetic potential is approximately equal. Therefore, the voltage and current reach balance at the output end, and the quantity is about equal and the voltage will be stablized as the nominal value.

To sum it up, by using the principle of magnetic balance and our unique technology, the power electricity can reach three phase balance. It reduce the wastes of the electricity. Shown on Figure 3.
