3BSE002348R1/SB511 ABB Standby Power Module Performance Parameters

Description

Integration gate in SB511 electronic integrated system (PEBB)
Based on the semiconductor components of pole commutated thyristors.
➔ 6。 In the power electronics integration system, integration
There are transducers. As per Avc ˇ E For pumped storage power plants
Engineering requirements, PCS 8000 AC excitation system
Set as follows: On the active rectifier unit (ARU),
Install two three-phase systems; In inverter device
A three-phase system is installed on (INU), and a single
Connect to the DC link ｜ 7. This structure is called
Make “12 pulse ARU active rectifier topology”
Structure “, in terms of harmonic processing performance

Great advantage. SB511 inverter device INU has four
Circuit parallel output, meeting the rotor required for rated operation
The current also includes the reserved power to meet the transient demand
Stream. Two voltage inverters pass through a DC link
Road connection ensures high flexibility during operation. both sides
The frequency, voltage and power factor of
And it is unnecessary to provide reactive power for the excitation system
Rate. The DC link is equipped with a voltage limiter (VLU).
The function of the voltage limiter is to ensure the
The voltage remains within the limits.
Integrated gate commutated thyristor IGCT semiconductor element
Is an advanced technology used in high-power converters
Technology equipment, which integrates turnoff thyristors
(GTO) and insulated gate bipolar transistor (IGBT) half
Advantages of conductors. Its conductive loss is low, like
GTO ； The state changes quickly, just like IGBT. take
IGBT and GTO are integrated, so there is thyristor

Flexible access to electricity 31
SB511 is not only related to the surrounding natural environment
The natural environment has also created considerable economic income
The Benefits of 8. It transforms the electric energy at the time of low power consumption
Peak energy for power station operators to operate freely
The flexible operation of the electricity market provides conditions.
At the same time, it also ensures the transmission lines in the surrounding areas
Stability, providing power grid control service providers with
Important reserve power. Av e pumped storage power
Double fed induction motor installed in the station, due to
And water pump mode, so even in
When not connected to the grid, power grid operators can also
As a standby unit, in case of sudden instability of the power grid
Start immediately when. The Shangku area is beautiful, and
The surrounding natural landscape is integrated, attracting countless
Tourists come for sightseeing. Of pumped storage power station
Construction, driving the development of local tourism
The region has created a lot of economic benefits.
