The Synchronous Condenser (SC) dynamically provides
power factor correction without the use of static components. As it is dynamic,
the precise operation of the Synchronous
Condenser (SC) excitation field will produce the required
pf VAR needed to correct the power factor to the set level or desired amount
without switching transients. Also, as it is a Dynamic device, there is
no problem with harmonic currents produces by (VFD's), dirty loads or static
(solid state) drives. The Synchronous Condenser (SC) uses
rotary technology which improves overall power quality by reducing voltage
transients and eliminating problems associated with harmonic distortion
which exist in all manufacturing processes.
How It Works
A Series SC is an unloaded or lightly loaded synchronous machine that will deliver the required reactive power dynamically. The SC is connected to the power line and is intentionally run in an overexcited condition. The level of excitation is dependent on the amount of power factor correction desired and the amount of power factor sensed by the condenser controls. The condenser will adjust the excitation level automatically to maintain the power factor at the correct setting. Once the Series SC is installed, it continuously monitors the power factor and produces the right amount of VAR needed to correct any power factor without switching transients and is not troubled by harmonic currents produced by solid state motor drives. The Series SC also helps overall power quality by reducing voltage transients and by reducing the problems associated with harmonic distortion found in many manufacturing process. The Series SC is available from 100 kVAR to 10,000 kVAR modules,
from 480 volts up to 15 KV.
Applying a synchronous condenser for power factor correction provides many advantages with no risks. Correcting power factor with a condenser is much smoother and will not adversely affect a system loaded with current harmonics. The condenser is a low impedance source and appears inductive to loads. In addition the Series SC is easy to maintain (a simple annual lubrication) and adapts easily to a plant's changing loads. (Dynamic Correction) The SC has many user friendly features such as the automatic restart after power loss. The SC also has a state-of-the-art integrated touch screen display and control interface. The controls are designed to be friendly and easily understood so that the user can control the SC from this panel. The touch screen will display voltage, current, power factor, and power information as a minimum.
