• Energy storage application of Changqing underground drilling left grid power

  During drilling operations, the applied capacity of grid power is 2500 ~ 4000kVA, and the voltage deviation is ±10%, which usually cannot meet the quantity requirements of power-driven fracturing and quality requirements of electric energy. Therefore, it's necessary to re-wire, resulting in an increase in electricity cost. Through the access of energy storage, the energy time shifting and power adjusting functions of energy storage and the left grid power in drilling operations are used to drive about 3 sets of power-driven fracturing machines to carry out oil gas fracturing operations, which can reduce the cost of transmission line construction and provide the power-driven proportion of fracturing operations.

  
  

  

• Solar power and diesel power storage system of camping house
