概述
Power electronics technology enables a new generation of FACTS devices for the power generation, transmission and distribution. SIFANG’s Static Var Compensator (STATCOM) and/or Energy Storage System response in milliseconds to compensate the active/reactive power, filter the harmonics, improve the power quality and balance the system. Depending on field-proven hardware and software platform and deep understanding of the power grid, SIFANG’s power electronic solution greatly improves the efficiency, reduces the capital investment and enhances the flexibility of your power system.
适用范围
New energy booster stations, power grid transmission and distribution, iron and steel metallurgy, rail transit, petroleum and petrochemical, mine, ports, etc. Especially applicable to comprehensive power quality control of electric furnace and rolling line.
特点
①The platform is improved safety and stability by hundreds of thousands of high voltage protection device.
②Fast regulation:closed-looped reactive current response time of up to 5ms, instantly compensates from rated capacitive to rated inductive.
③Strong compensation ability: constant and stable output ability, even when the voltage is down to 0.4pu, with high and low voltage riding through ability.
④Low harmonic: cascaded multi-level converter
⑤Strong adaption to system voltage unbalance: independent phase-locked ability in 5ms. During network unbalance fault, phase-locked error less than 5%.
⑥Perfect protection, alarms and warning signals, blocking SVG drive pulse and quit at the same time.
⑦Reactive power compensation includes AVC control, constant reactive control, constant power factor control and constant voltage control; Harmonic current compensation; Negative-phase sequence current compensation; Multi-comprehensive compensation.
⑧Ability to switch 4 FC simultaneously
