S-076N 3BHB009884R0021 High voltage frequency conversion framework IGCT
S-076N 3BHB009884R0021 The product in the picture is the photo of the product when it was released from the warehouse. The picture can clearly see the product situation. Because the model is relatively old, the product is older, the material is special, the weight and volume are heavier and larger, the supplier will connect the cable to do a simple product test when the product is released from the warehouse, and the goods will be sent out after ensuring that there is no problem with the product function. Also because the product is special, many enterprises lack technical wiring engineers to avoid the situation of junction box installation, so the junction box part will be placed on the frame as a reference;
The high-voltage S-076N 3BHB009884R0021 variable frequency regulation rack in IGCT is equipped with ABB thyristor configuration for remote offshore wind farms. The power grid connection uses high-voltage direct current technology. In order to reduce losses and maximize profitability, it is necessary to minimize semiconductor power losses. In order to select semiconductors correctly, it is necessary to estimate their losses under a large number of operating conditions. This article discusses a modeling method for calculating power loss under many such operating conditions based on measured semiconductor characteristics and selected multilevel modulation strategies. The reason for considering the case of integrated gate commutated thyristors is that, for a given device rating, an integrated gate commutated thyristor can be selected, which benefits from a good compromise between conduction loss and turn off loss, thereby minimizing power loss at both end stations. With the increasing popularity of renewable energy, offshore wind farms located 50 to 80 kilometers from the coast can stably recover energy from strong winds. Due to the importance of the length of submarine cables, the connection to the onshore AC power grid is achieved through HVDC links. Over the years, modular multilevel converters (MMC) have been widely used in such applications; Nowadays, these converters can transmit power with inter electrode voltages of up to several hundred kilovolts. This topology is based on a large number of semiconductors: their characteristics are crucial for ensuring the continuous operation, efficiency, and low capital expenditure (CAPEX) of HVDC links.
