  • Static Synchronous Compensator For Electric Traction - China

    price: contact company for price

    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.
