Recently, all five stations of HV Mobile Substation Project supplied by XJ Electric Corporation (abbreviated to XJEC) to Saudi Electricity Company (SEC) have been successfully put into operation and connected to the grid.

The integrated automation system supplied by XJEC can be called the “smart brain” that controls the entire mobile substation. The monitoring system can respond to changes in the operating status of the power system in real time and the protection, measurement and control device can flexibly edit the protection logic and functional configuration as needed.

The AC and DC power supply system supplied by XJEC can transmit stable electricity to every electrical equipment like a “heart and energy warehouse”.

The MV and secondary vehicle integration of 132kV vehicle-mounted mobile substation completed by XJEC achieves qualitative transformation from fragmented devices to an integrated system organism through precision coupling of core components. MV switchgear operates with surgical precision like “steady hands”,  empowering this “steel giant” to deliver full-capacity operation in 55℃ scorching desert heat.

33kV + 13.8kV “Dual Voltage”

In response to the actual needs of SEC, the gas-insulated switchgear and station transformer upgraded by XJEC innovatively realize “two voltages for one set of equipment”, which can meet the operation requirements of 33 kV and 13.8 kV at the same time, effectively reducing the equipment retrofit cost for customers while achieving more flexible power grid operation and more convenient operation and maintenance. 

3D-optimized Layout Slims down the Entire Vehicle by 30%

The 3D vehicle-mounted structure maximizes vertical space utilization，integrating core units such as switchgears, control and protection equipment, and AC and DC power supply equipment. As a result, the overall length of the vehicle is shortened, the center of gravity is lowered, and the transport maneuverability is significantly improved. Moreover, modular interfaces enable plug-and-play on site, reducing the installation and commissioning time by over 40%.
