On October 29, 2018, the project titled "Study on the Comprehensive Defense System of Megacity Power Grid under Sudden Extreme Faults," led by the Stabilization Company, successfully passed the on-site acceptance organized by Shenzhen Power Supply Bureau Co., Ltd. in Shenzhen, Guangdong. This milestone marks a significant step forward in enhancing the resilience of power grids in large cities against unexpected and extreme events.
As China's economy continues to grow and urbanization accelerates, the scale and number of megacities are increasing rapidly. According to long-term forecasts, the power demand in many large and medium-sized cities will surge over the next decade or two. With this growth comes an urgent need for more robust and reliable power systems.
However, sudden extreme faults—such as typhoons, heavy storms, and other natural disasters—can cause widespread power outages with severe consequences. Establishing a comprehensive defense system for megacity power grids is therefore essential for maintaining economic stability and social well-being.
In response, the Shenzhen Power Supply Bureau launched a tender in 2017 for a research project focused on developing a comprehensive defense system for power grids facing sudden extreme faults. The project aimed to explore key technologies such as network model integration, automatic fault set generation, real-time safety analysis, and decision support systems.
After one year of intensive research, the State Grid Nanrui Stabilization Company developed a comprehensive framework for managing power grid risks during extreme events. Their work included risk assessment, early warning systems, and advanced data integration techniques that enhance situational awareness and decision-making capabilities.
The team also introduced a multi-level scheduling data integration method, incorporating topology-based identification and safety impact analysis. They proposed an online safety and stability analysis approach tailored for typhoon-prone areas, using geographic models and weather data to predict fault probabilities accurately.
During the acceptance review, experts carefully examined the project’s findings and concluded that all objectives had been met. The results exceeded expectations and demonstrated strong potential for practical application.
This breakthrough enables better analysis, prediction, and decision support for power grid operations under extreme conditions. It helps operators respond more effectively to sudden weather-related disruptions, ultimately improving the safety and reliability of the power grid.
This achievement not only strengthens the technical foundation for grid management but also sets a new standard for smart and resilient power infrastructure in megacities. (Source: Nanrui Group Co., Ltd., Tendering Network, and News)
Designed to perform the shearing and removal of the excess of metal accumulated during the welding, leveling in a homogeneous way the portion of the welded rail. It consists of a powerful hand pump which moves two hydraulic cylinders with the mobile shearing blade applied on, that, during the removing of the material, leans against the fixed cutting blades. The cutting blades are easily replaceable so as to adapt the tool to the rail profile to be processed. Two handles are placed in a well-balanced point, allowing an easy movement of the machine.
