Features：

◆ The electronic control system includes an AC variable frequency system (VFD) and a direct current drive system (SCR).

◆ The electronic control system includes an AC variable frequency system (VFD) and a direct current drive system (SCR).The DC drive (SCR) system consists of generator control cabinet, SCR control cabinet, PLC control cabinet and MCC control cabinet. The system adopts AC-SCR-DC electric drive mode, which can realize one-to-one or one-to-many control mode, with modular structural rectification assembly, maintenance is much easier.The AC variable frequency (VFD) system consists of generator control, rectification inverter system, energy consumption braking, PLC unit and MCC system. The system adopts AC-VFD-AC electric drivesystem mode, The frequency conversion control is highly precision and flexible. The winch frequency conversion speed control adopts speed closed-loop control to ensure that the system can generate high starting torque and winch zero rotary speed output maximumtorque (hover function).

◆ The system adopts optimized design and reasonable layout, which makes the operation simple and reliable. It adopts real-time monitoring to indicate, alarm and protect timely whenever the malfunction occurs; In the internal device arrangement, it adopts special modular structure for quick disassembly and installation, so that reduce maintenance time and system down time.
