Maerblock Hydropower Station is the highest hydropower station under construction in the upper reaches of the Yellow River with the largest installed capacity, one of the backbone power points of the national "West-east power transmission" and "Qingyuan-DC" supporting stations, and the core project of the "water-light savings" multi-energy complementary integration of 10 million kilowatts of clean energy base built by Qinghai Province. It is also a milestone project in the development and manufacturing of large mixed-flow units in high altitude areas of Dongfang Electric. The total installed capacity of the power station is 2320 MW. It is planned to build 4 units with a capacity of 550 MW and 1 unit with a capacity of 120 MW. All units are developed and supplied by Dongfang Electric.

Maer hydropower station unit is a new generation hydropower unit developed by Dongfang Electric to adapt to the integrated operation of water landscape (storage). In recent years, the construction of new power systems has been accelerated, wind power, photovoltaic and other new energy sources have developed rapidly, Dongfang Electric combined with the new requirements for hydropower units under the integrated operating conditions of water landscape (storage), and applied new design concepts to develop a new generation of intelligent hydropower units with high hydraulic stability, high structural reliability and high system safety. To build a multi-energy, complementary and integrated clean energy base in Qinghai Province and to serve national energy security, inject "eastern strength".

Dongfang Electric applied a large number of unit intelligent technologies in the Marblock project to effectively support users to build smart power stations. For the first time in the industry, the innovative edge distributed intelligent acquisition system is adopted to achieve all platinum thermal resistance temperature sensor signals in situ acquisition, edge computing and configuration logic output, greatly reducing the total amount of cables, while avoiding signal interference along the way, improving data reliability and real-time. The all-fiber temperature monitoring system is innovated for the first time to realize stator replaceable temperature measurement and rotor temperature all-fiber monitoring, which solves the defects of traditional resistance sensors such as jump and high breakage rate, and eliminates the blind spot of rotor temperature monitoring. In addition, it is equipped with advanced monitoring technologies such as rotor visual recognition, infrared thermal imaging system and voicing monitoring system to realize comprehensive online monitoring of key indicators of unit operation, providing a rich data basis for unit health assessment and fault diagnosis.
