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

Electric locomotive applies single phase power supply, which

causes severe three-phase unbalance of the power grid, reduces

the power factor and generates negative sequence current. SVC

uses split phase quick compensation function to balance the

three-phase power grid and increase the power factor.

of 35kV.Based on the voltage change features of wind power

system, G-SVC adopts advanced reliable control platform and

control algorithm to adjust the reactive power value instantly,

continuously and smoothly, suppress the voltage fluctuation

and flicker effectively, filter harmonic, and improve the system

stability as well. It has been in good operation condition since it

was put into service.

2.SVC project at Beiman Special Steel Co., Ltd. of

Northeast Special Steel Group

In July of 2008, Zhejiang Guirong Xieping Technology Co., Ltd.

made reconstructive repair for the SVC installed at a matched

220kV substation for a 90 tons ultra high power electric arc

furnace at Beiman Special Steel Co., Ltd of Dongbei Special

Steel Group. It used to be the biggest single TCR model SVC

with power supply voltage of 35kV and compensating capacity

of 127M. In April of 2008, there was a serious accident that the

main components such as capacitors and reactors etc. mostly

burned down. After checking and analyzing this malfunction,

our engineers found out the fault cause and presented the

reconstructive repair proposal according to the manufacturing

technique of electric arc furnace and actual situation of power

supply system. After more than two months of repair and

rectification, the SVC operated successfully in July of 2008. It

operated steadily and all parameter indicators such as voltage

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.
