ELECTRIC DRIVE SYSTEM
Inquire NowDescription
The ELECTRIC DRIVE SYSTEM by HH is a sophisticated solution designed to optimize the performance and efficiency of drilling operations. This system encompasses a comprehensive low-voltage electric drive setup, including an MCC system, wellsite circuit, and lighting system. With two distinct types of drives—AC drive (VFD) and DC drive (SCR)—the electric drive system offers versatility tailored to specific operational needs.
The VFD (Variable Frequency Drive) is integral to the AC rig, featuring modules such as generator control, rectifier, inverter, dynamic brake, and a PLC control system. Equipped with either ABB or SIEMENS direct torque converters and a shared DC bus, the VFD system excels in controlling drawworks, mud pumps, and rotary tables with precision. Its closed-loop control ensures high starting torque and enhances dynamic response during low-speed operations, achieving maximum output torque even at zero speed.
In stark contrast, the DC Drive (SCR) system comprises generator controls, SCR control cabinet, and similar components tailored for driving various DC motors through a single SCR cabinet. Its design allows for simple commissioning and includes a self-diagnosis function, ensuring reliability and ease of maintenance.
