Solutions-GoLead Intelligent

Background and Challenges

The petrochemical industry places extremely high demands on the stability and reliability of power systems, facing the following key challenges:

High Risk of Power Interruptions

Instability in power supply—including outages or fluctuations—can directly lead to production line shutdowns and generation of off-spec products or waste materials, while also posing risks of physical damage to production equipment. This significantly increases subsequent maintenance and replacement costs, resulting in substantial economic losses.
Frequent Load Fluctuations

The petrochemical industry involves various high-power impact loads, such as drilling rigs and water injection pumps, which generate large transient currents during startup. These conditions easily cause voltage fluctuations and inrush current issues, requiring power systems with fast dynamic response capability.
Complex Operational Conditions

Power systems in the oil and petrochemical sector must deliver high reliability and maintain safe, stable operation under complex and demanding electrical environments.

Key Technologies

High-Precision Automatic Synchronization and Grid-Connection Control

The solution provides high-precision automatic synchronization control with a phase angle deviation of ≤ 0.5°, ensuring accurate and reliable grid connection of generator units and meeting the petrochemical industry’s stringent requirements for power supply stability. In alignment with localization initiatives, GoLead Intelligent has independently developed fully reliable, domestically engineered synchronization devices, ensuring long-term stability, controllability, and compliance with localization requirements.
Millisecond-Level Seamless Fast Transfer

Featuring stable and highly reliable fast transfer technology supported by multiple patented innovations, the solution supports various transfer modes and achieves an end-to-end switching time of ≤ 20 ms (detection ≤ 5 ms, opening ≤ 5 ms, closing ≤ 10 ms), far outperforming conventional automatic transfer schemes with response times of around 500 ms. This millisecond-level, disturbance-free transfer capability ensures uninterrupted power supply to critical petrochemical loads during power source switching, maintaining overall system stability.
Smart Inrush Current and Overvoltage Suppression

By adopting smart phase-controlled devices, the solution effectively suppresses magnetizing inrush currents and switching overvoltages generated during breaker closing, significantly reducing electrical stress on power lines and equipment. Optimized phase-selection control further minimizes the risk of arc restrike, protects sensitive petrochemical equipment, and extends overall equipment service life, ensuring stable and reliable system operation.
Deep Integration of Primary and Secondary Equipment

Through deep integration and coordinated control of primary and secondary equipment—such as high-speed circuit breakers working in conjunction with fast transfer devices—the solution achieves a fully optimized power switching process with an overall transfer time of ≤ 20 ms. This integrated architecture significantly enhances system response speed, coordination efficiency, and operational reliability, delivering a robust and smart power system tailored to complex petrochemical operating environments.

Application Results and Cases

In an application at a large petrochemical enterprise, the solution significantly improved overall power system performance by achieving 100% power supply continuity for critical loads, effectively eliminating equipment shutdowns caused by power source switching. Through advanced inrush current suppression and overvoltage protection, the equipment failure rate was reduced by 30%, extending service life and enhancing long-term reliability. In addition, smart monitoring and diagnostic functions reduced the frequency of manual inspections, resulting in higher operation and maintenance efficiency.
