It is common in applications mainly in the chemical industry for compressors and fans to be driven by steam turbines. Against the backdrop of improving energy efficiency and reducing carbon emissions, the need to convert from steam turbine drives to electric motor drives is becoming increasingly urgent. Due to differences in physical principles, starting from the thermal power input end, the efficiency of electric motor drives powered by the grid is much higher than that of small steam turbine drives. In recent years, with the advancement of high-power motors and drive control technology, this advantage has become even more significant. As the proportion of renewable energy connected to the grid continues to increase, the carbon emission levels of systems using electric motor drives will further decrease in the future. Wolong Electric Drive (600580) has decades of operating and service experience in the chemical industry, and its extensive product line has been widely applied in various process power systems. In response to the trend of converting steam to electric, Wolong, based on a deep understanding of industry needs and combining years of technical accumulation and product iteration, has launched a complete system solution covering different power levels and application requirements, from electrical, drive, motor to automation. Depending on the scope of different requirements, various types of complete solutions can be provided, capable of meeting load drive requirements below 80,000 kW or speeds below 20,000 rpm/min, matching different compressor load process needs. The motor drive system mainly consists of motors, frequency converters, transformers, and control systems, replacing the steam turbine and its water, oil, steam, and other systems in the original steam turbine unit, making the structure simpler and maintenance more convenient. The new steam-to-electric drive control system features an integrated design of motor and control system, meeting the needs for high efficiency, energy saving, and safety. Its main functions include: l Highly integrated, multiple protections, friendly human-machine interaction, worry-free operation. Multiple safety protection functions can be set, such as overvoltage, overcurrent, undervoltage, phase loss, short circuit, stall (for synchronous motors), reverse, overload, overheat, instantaneous power failure, and communication faults. l No harmonic interference to the motor and grid, no cable length limit, and the motor is less affected by common-mode voltage and dV/dt stress. l The control unit does not cause motor resonance, with torque ripple less than 0.1%; vector control and logic control can be achieved. l High efficiency and energy saving, reducing carbon emissions, with overall system efficiency improved by 10% to 40%. The system is simple, occupies less space, has fewer failure points, is easier to maintain, features intelligent control, good starting performance, and high operating efficiency. Provide users with a full range of EPC turnkey services from system design, scientific implementation, to thoughtful delivery, achieving one-stop service for users.
