Power electronics
Applications
Substation
In the regional power grid, multi-stage thyristor switched
capacitor banks are generally used to compensate system
reactive power and improve power factor. This method has the
following disadvantages:
1. It can only provide capacitive reactive power, and it cannot
make accurate regulation along with the changes of loads.
2. It can easily over-compensate the system in light load,
increase the bus voltage, and damage the stability of the electric
equipment and system.
SVC system can accurately make capacitive and inductive
reactive power compensation, which helps to solve the over-
compensation problems thoroughly and conveniently while
stabilizing bus voltage and improving power factor.
Arc Furnace
When the electric arc furnace is connected with the power
grid as the nonlinear and irregular loads, it will cause harmful
influences to the power grid, which mainly include:
1. They cause severe three-phase unbalance of the power grid,
and generate negative sequence current
2. They generate higher harmonics, usually 2nd, 4th even
harmonics and 3rd, 5th, 7th odd harmonics often co-exist
3. They cause voltage fluctuation and voltage flicker
4. They reduce power factor
SVC has fast response speed, which can quickly provide
reactive current for the electric arc furnace, stabilize the bus and
grid voltage and reduce the flicker influence. The split phase
compensation function of SVC can eliminate three-phase
unbalance, and filter can eliminate harmful higher harmonics
and provide the system with capacitive reactive power to
improve power factor.
Rolling Mill
The reactive impulse caused by rolling mill and other industrial
symmetrical loads during operation will cause the following
influences:
1. They cause voltage fluctuation of the power grid.
2. They reduce power factor
3. They generate harmful higher harmonics, which are
represented by 5th, 7th, 11th, 13th odd harmonics, causing
severe voltage distortion of the power grid.
Example 1
The valid value curve of 6kV system voltage before SVC
activation is shown in the figure. There are obvious voltage
drops during the rolling mill operation. The maximum voltage
drop is 7.3%.
The valid value curve of 6kV system voltage after SVC activation
is shown in the figure. The voltage drops are reduced during
rolling mill operation, and the maximum voltage drop is 1.9%,
which meets the national standard.
Wind Power Industry
Since the wind power cannot be constant, the power generated
by the wind farm is constantly changing, and SVC fast response
to power changes can perfectly compensate the power
generated by the wind farm.
Hoister
Hoisting machine and heavy-industry loads will influence the
power grid in the following aspects;
1. They cause voltage fluctuation of the power grid
2. They reduce power factor
3. They generate harmful higher harmonics.
Above issues can be perfectly solved after applying SVC.
P=Arc furnace power active power SVC=SVC connection
U=Arc furnace busbar voltage ORI=without compensation
Above issues can be perfectly solved after applying SVC
system, which maintains the bus voltage stability and eliminate
harmonic interference.

Electric locomotive applies single phase power supply, which
causes severe three-phase unbalance of the power grid, reduces

fluctuation, voltage flicker, harmonic and three-phase unbalance
of the power grid achieved the national standard. The successful
operation of the SVC not only ensures normal production
activities but also brings good economic benefits for users.
