Restrain voltage fluctuation and flicker
Eliminate harmonics
Improve the the stability of power transmission and power
factor
Technical Advantages
Static Synchronous Compensator has the following advantages
compared with traditional compensation methods:
Faster response speed
STATCOM response time: ≤5ms
Traditional static compensator response time: ≥10ms.
STATCOM can finish the conversion from rated capacitance var
to rated inductance var in a very short time.
This
unexampled response speed makes STATCOM very suitable for
impact load compensation.
Stronger voltage flicker restrain capability
SVC can restrain voltage flicker to 2: 1 in maximum, but
STATCOM can achieve 5: 1, even higher.
SVC cannot improve its
capability for voltage flicker mitigation even with high
capacity because of low response speed.
But STATCOM responds
fast.
When its
capacity is increased, the capability of voltage flicker
mitigation can be further improved.
Wide operation range
STATCOM can work from rated inductive power to rated
capacitive power.
So compared with SVC, STATCOM operation
range is much wider.
Furthermore, STATCOM can output rated
reactive current even under low system voltage.
Multiple compensation function
STATCOM is not only functioned as fast reactive power
compensator, but also harmonics and unbalance compensator
according
to different demands of different clients.
Low harmonic content
STATCOM utilizes PWM, 3-level and multiple technologies.
Therefore, it generates very low harmonics with compensating
load
harmonics at the same time.
Thus, STATCOM becomes a true
multifunctional compensator.
Small volume
HV big capacitors and reactors are not necessary.
STATCOM
installation area is greatly smaller than that of the same
capacity SVC, only 50% or even lower.
At the same time, Wanlida cooperates with the No.
1 Science
university in China---Tsinghua University to develop SVG,
but the most important advantage for Wanlida is that we have
many years experiences for Medium voltage variable frequency
drives technology, because the Static Var Generator has
almost structure and technology with Medium voltage variable
frequency drives, in addition, Wanlida has over 21 years
experiences for protection relays for reactor, capacitor
etc.
Technical Features
Provides fast smooth dynamic compensation from inductive to
capacitive in reactive power, also eradicates reactive power
delivery to power grid, it can meet the maximum request to
compensate power factor and keep power factor close to 1.0
anytime.
Low power loss, more better economical operation.
Has powerful capability to support voltage and ability to
continuously operate under the 1.1 times of overload.
More fast response time and better effect for restraining
flicker.
Produce no harmonic and and compensate nearly all load
harmonics without amplifying them and without generating
harmonic resonance, it has more safety, stability and
reliability because it is not sensitive to the system power
parameters.
Modular design.
All power units are the same in structure
and electric performance, thus they are interchangeable,
which is easy for installation and maintenance.
Redundant
N+1 structure provides more higher reliability.
