Hande launched the third-generation electric control system for electric oil drilling with DC transmission and AC drive. The main structure of the system power transmission is DC-AC control system; DC power generation, DC transmission, and AC drive system. The key core technology of electronic control has seven patents, filling the gap of intelligent and modern advanced drilling rig control technology in the petroleum system.

System advantages:

(1) Eliminate the influence between the prime mover's speed and the bus frequency, and improve the stability of the parallel generator set

(2) The use of DC generator and DC transmission system with capacitive storage equipment eliminates the influence of harmonics

(3) The energy generated when the winch is lowered or the motor is decelerated is recovered through the energy recovery system, which improves the energy utilization rate

(4) Equipped with a super capacitor energy compensation system to improve the stability of the system when the load changes suddenly, and improve the system's anti-shock ability
