Introduction:



STATCOM (Static Synchronous Compensator, also known as SVG ) represents the most advanced technology in the reactive power compensation field. As an indispensable part of Flexible AC Transmission Systems (FACTS), STATCOM is a shunt device in the power grid and acts as a controllable reactive current source to provide variable reactive power in response to load reactive current instantly and continuously. In the meantime, the function of harmonic filtration can be performed by STATCOM to meet the grid code requirements further. As a result, a STATCOM system, which is capable of providing dynamic reactive power to stabilize the system voltage, PF correction and harmonic mitigation, serves as the ultimate power quality solution in the power grid.


Specifically, Hoteam LV HTSVG uses IGBTs to form a self-commutated converter, which is connected to the power grid via coupling reactors. By adjusting the amplitude and phase angle of output voltage on the AC side of the converter, or just controlling the current on the AC side directly, the circuit can absorb or generate required reactive current to fulfil the purpose of dynamic reactive power compensation.


Functions:


1.Maintaining load side voltage and improving reliability of electrical distribution system.

For load center, heavy load burden without the proper support of large capacity reactive power supply can easily lead to low grid voltage or stability accident like voltage collapse. With the STATCOM’s dynamic reactive power compensation ability, the voltage at the load side and grid stability can be raised effectively.


2.Compensating reactive power, improving power factor, lowering line loss and enhancing energy efficiency

From the point of view of electrical distribution system, large loads like induction motors, arc furnaces, rolling mills and large capacity rectification equipment, require large amount of reactive power during operation. In the meantime, the transformers and line impendence cab also generate reactive power demand. All these factors combined lower the power factor of the system. Hoteam STATCOM improve the power factor of the load by injecting suitable reactive power in the power distribution line.


3.Mitigation of voltage fluctuation and flicker

Voltage fluctuation and flicker are mainly caused by load fluctuation. This is because load fluctuation will result in current fluctuation, which in return causes voltage flicker at the load side. Typical loads causing voltage flicker are arc furnaces, rolling mills and electric locomotives.Hoteam STATCOM can provide dynamic reactive current super fast to mitigate voltage fluctuation and flicker caused by load fluctuation. To date, the most effective solution to voltage fluctuation and flicker is STATCOM.


4.Harmonic compensation

The non-linear loads prevailing in electrical distribution system, such as VFDs, rubber mixers, hoists and arc furnaces,generate large amounts of harmonics. Those harmonics distort voltage and current waveform, increase failure rate of loads and power loss throughout the distribution system, or cause system resonance and related tripping accidents.To solve the harmonic issues, H type HTSVG LV STATCOM can cancel harmonics by injecting reversed-phase harmonic current into grid. The maximum harmonic compensation capacity of H type HTSVG STATCOM is 30% of rated power.
