Bohai No.8 Platform 2000kVA Variable Frequency Variable Voltage Power Supply Project

Shandong Boos cooperates with CNOOC to provide the Bohai 8 platform with variable frequency and variable voltage power supply solutions to power the surrounding drilling platforms, help them improve the reliability of power supply and reduce the environmental impact on the port and surrounding areas

The project is based on the demand of China's offshore oil operations, and the environmental impact caused by the need for a branch port and surrounding areas. Hold the platform to support the operation of the whole vigorous oilfield. According to the operation requirements, the support platform itself will not generate power, but the production platform will reverse power supply. Therefore, it is necessary to purchase a variable frequency and variable voltage power supply to supply power for the support platform. The power input is 10.5KV, 50Hz, and the output is 600V, 60Hz, supplying power to the platform, with a total power of 2000KVA. The power supply can be divided into two parts: power conversion main circuit and control circuit. The main circuit adopts AC-AC structure, including rectifier, DC filter, inverter, AC filter and transformer. Among them, the input is rectified by multi pulse phase-shifting to eliminate grid harmonics. Previously, the ship used diesel generators to generate electricity for the surrounding drilling platforms. Due to the large oil consumption of diesel generators, which are easy to be polluted, the pure power supply is obtained through the voltage reduction and frequency conversion of our company's shore power supply to meet the needs of the operation and life of the surrounding drilling platforms, reduce oil consumption and improve the quality of power supply.
